v0.1.6 beta — New player names (callnames), Switch optimizations on PC, lighter graphics

Beta. Expect bugs. Windows 10/11 x64 (Linux and Steam Deck: build it yourself, see below).

🎬 Screenshots and the technical story (how the game's voice banks and name lists work, and which Switch optimizations paid off on PC) are in the v0.1.6 discussion.

What's new

New player names for the commentators (callnames, experimental)

Players the game never knew (Acuña Jr., Chourio, Ohtani, Yamamoto…) can now have their name called in the booth.

• A callname mod adds up to three recordings per name: the main commentator saying the name, the same name excited, and the color commentator saying the full name. Missing variants use the normal one.
• Bring your own audio: WAV or MP3, up to 5 seconds. Nothing of the game's audio is involved; use recordings you made or are allowed to use.
• SETTINGS > TOOLS > CALLNAME EDITOR creates them without writing files by hand: pick or create a mod, Add, type the name as the game will list it (it shows how it will look), choose the audio files, Listen, Save. Voice numbers (7223–10239, about 3,000 free slots) are picked for you.
• New names show up in the game's own editor (Arrange › VOICE SETUP › Select Type) and in PowerUp+ (MODS › EDIT ROSTER) as Callname , so you can give them to any player.

See docs/en/callname-studio.md and the Callnames section of docs/en/mods.md.

Faster on the CPU: Switch optimizations brought to PC

The work that took the Nintendo Switch port to 60 fps now runs on PC too: native versions of the game's helmet and bat reflection math, per-mesh light colors, reverb and math routines (each one checked to give exactly the same result as the original), a faster translator output, faster graphics command handling and faster mipmap creation.

On the test PC (Ryzen 5 5500) the game thread does 13% less work per frame (6.16 → 5.38 ms) and the worst frames are a little steadier. Frame rate stays at 60 fps (it was already there); the gain is headroom for modest PCs and the Steam Deck.

Lighter graphics options (SETTINGS > VIDEO, experimental)

• PLAYER SHADOWS: Full (original), Simple (a round patch under each player) or Off.
• CROWD: Full (original), Less or Off.
• PLAY CAMERA: field of view of the camera that follows the ball after it is hit, 100% (original) down to 60%. At low values a fielder can end up near the edge of the picture.
• REFLECTIONS: the shine on helmets and the bat, Full (original) or Off.

All of them are as the original game by default and only change how the game looks, never how it plays.

Fixed

• MLB Life, creating a two-way player (Pitcher + second position, Ohtani rule on): he now stays a pitcher after creation, and you also pick two batting advantages and one batting disadvantage after the pitching ones (B goes back). Both sets are applied to the new player.
• Windows Defender: the Setup and the launcher no longer start programs in a way antivirus heuristics flag, and the Setup now carries version information. One player's Defender had quarantined the v0.1.5 Setup during an update.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.6.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL (about 4–5 minutes on a 12-thread CPU), then PLAY.

Coming from an older version? After installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

Linux / Steam Deck: download the kit for your system and run its installer; it compiles the game from your own copy (see docs/en/linux.md). The Blender stadium add-on is unchanged (powerpros_stadium-0.8.2.zip, attached again).

Known issues

• Callnames are new and experimental: tested in Exhibition matches; MLB Life uses the same commentary code but has not been checked by ear yet. Names in the game's list are up to 15 characters, without accents.
• Linux / Steam Deck: the Callname Editor is Windows only for now; on Linux write callnames/callnames.toml by hand (see docs/en/mods.md) or make the mod on Windows and copy it.
• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500).
• New stadiums appear only in Exhibition.
• The game can occasionally hang at startup: close it and open it again.

If something goes wrong, please open an issue with your CPU, GPU and UserData\Logs\<latest>\console.log; for MLB Life or Season, your save helps a lot.

🎬 Capturas y el apartado técnico (cómo funcionan los bancos de voz y las listas de nombres del juego, y qué optimizaciones de Switch sirvieron en PC) están en la discusión de la v0.1.6.

Beta. Puede tener errores. Windows 10/11 de 64 bits (Linux y Steam Deck: compílalo tú).

Nombres de jugador nuevos para los comentaristas (callnames, experimental): jugadores que el juego no conocía (Acuña Jr., Chourio, Ohtani, Yamamoto…) ya pueden tener su nombre en la narración. Cada nombre lleva hasta tres grabaciones: el comentarista principal diciéndolo, el mismo nombre emocionado y el comentarista de fondo con el nombre completo (si falta alguna se usa la normal). El audio lo pones tú (WAV o MP3, hasta 5 segundos). AJUSTES > HERRAMIENTAS > EDITOR DE CALLNAMES los crea sin escribir archivos a mano (elige números de voz libres entre 7223 y 10239). Salen en el editor del juego (Arrange › VOICE SETUP › Select Type) y en PowerUp+ (MODS › EDITAR ROSTER) como Callname .

Más ligero en la CPU: las optimizaciones que llevaron la Switch a 60 fps ahora también están en PC (nativas exactas de los reflejos de cascos y bate, colores de luz por malla, reverb y rutinas matemáticas; traductor, comandos gráficos y mipmaps más rápidos). En la PC de prueba el hilo del juego trabaja un 13 % menos por cuadro (6,16 → 5,38 ms). Sigue a 60 fps; la ganancia es margen para PCs modestas y la Steam Deck.

Opciones gráficas más ligeras (AJUSTES > VIDEO, experimental): SOMBRAS DE JUGADORES (completas, simples o sin sombras), PÚBLICO (completo, menos o sin público), CÁMARA DE JUGADA (del 100 % original al 60 %) y REFLEJOS (con o sin el brillo de cascos y bate). Por defecto todo es como el original y solo cambia cómo se ve.

Corregido: MLB Life, crear un jugador de dos vías (Pitcher + segunda posición, con la regla Ohtani): ahora sigue siendo pitcher tras la creación y también eliges dos ventajas y una desventaja de bateo después de las de pitcheo (B vuelve atrás); se aplican las dos tandas. Además, el Setup y el launcher ya no arrancan programas de una forma que marcan las heurísticas de los antivirus, y el Setup lleva información de versión (Defender había puesto en cuarentena el Setup v0.1.5 de un jugador).

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.6.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de una versión anterior, copia UserData\NAND, UserData\ModSaves y la carpeta mods de la instalación vieja a la nueva.

Problemas conocidos: los callnames son nuevos y experimentales (probados en Exhibición; en MLB Life usan el mismo código pero no se han escuchado todavía; en la lista del juego, hasta 15 caracteres y sin acentos); en Linux y Steam Deck el Editor de callnames aún no existe (escribe callnames/callnames.toml a mano o crea el mod en Windows y cópialo); se probó sobre todo en una PC; los estadios nuevos solo salen en Exhibición; a veces se cuelga al arrancar.

v0.1.5 beta — Two-way players (Ohtani rule), AI texture upscaling

Beta. Expect bugs. Windows 10/11 x64 (Linux and Steam Deck: build it yourself, see below). Thanks to everyone who reported the v0.1.4 controller bug so quickly.

🎬 Video, screenshots and the technical story (how MLB Life decides who pitches, the manager's dialogue scripts, texture names vs. Dolphin) are in the v0.1.5 discussion.

What's new

Two-way players (the "Ohtani rule", experimental)

Turn it on in SETTINGS > ENHANCEMENTS > OHTANI RULE.

• A starting pitcher can also be the DH and keep batting after he leaves the mound, as in the majors since 2022. In the lineup, on PITCHER, make the player who is the DH the starter (Ohtani, say): he keeps both spots and the team's former starter goes to the bullpen. Works in every mode with the DH.
• Automatic lineups know two-way players (Season, MLB Life, CPU teams): a pitcher who can also hit (aptitude 4+ at a fielding position, or a hitter's batting, like Ohtani in updated rosters) is the DH on the days he does not start, and P and DH on the day he does.
• MLB Career: choosing Pitcher when creating a player now asks Select Second Position, like Pawapuro's two-way players.
• MLB Life with a two-way player:
  • He starts every fifth game of his team (by the real schedule; off days do not count) and is the DH in the others. Without the DH, he starts and bats as the pitcher.
  • Talk to the manager (FREE > CHAT > STAFF > MLB Manager > About my two-way role.) to choose Two-way player, Batter only (DH every game) or Pitcher only. It is saved and you can change it again any time.
  • X on the practice list switches between pitcher and batter drills, and the bottom panel shows the matching abilities.
  • X on the MLB Life menu switches the stats panel between ERA, W-L, K, SV and AVG, HR, RBI, SB.
  • The look back after a game and ability growth follow what he did that day: pitched, or only batted.

Texture Studio

• Upscale with AI: pick a category (menus, a stadium…) or one texture, press it, and it upscales them x2 or x4 on your graphics card (Real-ESRGAN; AnimeSharp by default) and imports them into your mod. The first time it downloads the engine and the model from their authors (about 80 MB; nothing of it comes with the game). Works on AMD, NVIDIA and Intel.
• Dolphin pack...: import a Dolphin texture pack for MLB Power Pros 2008 (folder or .zip) as it is. Our texture names are Dolphin's, so packs made for Dolphin work here.

See docs/en/texture-studio.md.

Fixed

• MLB Life: History no longer crashes when a season pack (start year, schedules) is enabled.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.5.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL (about 4–5 minutes on a 12-thread CPU), then PLAY.

Coming from an older version? After installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

Linux / Steam Deck: download the kit for your system and run its installer; it compiles the game from your own copy (see docs/en/linux.md). The Blender stadium add-on is unchanged (powerpros_stadium-0.8.2.zip, attached again).

Known issues

• Two-way players are new and experimental: the MLB Life rotation is a fixed five-game turn (it does not follow fatigue), "Pitcher only" sits him out on the other days, and a batter with pitching ability is not offered the two-way role yet.
• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500).
• Copy / Paste / Import / Export of passwords use a mouse or a GameCube-style controller; not the Wii Remote yet.
• New stadiums appear only in Exhibition.
• The game can occasionally hang at startup: close it and open it again.

If something goes wrong, please open an issue with your CPU, GPU and UserData\Logs\<latest>\console.log; for MLB Life or Season, your save helps a lot.

🎬 Vídeo, capturas y el apartado técnico (cómo decide MLB Life quién lanza, los guiones de diálogo del mánager, los nombres de textura frente a Dolphin) están en la discusión de la v0.1.5.

Beta. Puede tener errores. Windows 10/11 de 64 bits (Linux y Steam Deck: compílalo tú).

Jugadores de dos vías («regla Ohtani», experimental): se activa en AJUSTES > MEJORAS > REGLA OHTANI.

• Un pitcher abridor también puede ser el DH y seguir bateando al dejar el montículo. En la alineación, en PITCHER, pon de abridor al jugador que está de DH (por ejemplo Ohtani). Sirve en todos los modos con DH.
• Las alineaciones automáticas (Temporada, MLB Life, equipos de la CPU) ponen a un pitcher de dos vías de DH los días que no abre y de P y DH el día que abre.
• MLB Career: al crear un pitcher, el juego pregunta Select Second Position.
• MLB Life: abre cada cinco partidos de su equipo y es el DH en los demás; habla con el mánager (FREE > CHAT > STAFF > MLB Manager > About my two-way role.) para elegir dos vías, solo bateador o solo pitcher (se guarda y se puede cambiar); X en el entrenamiento cambia entre ejercicios de pitcher y de bateador con su panel; X en el menú cambia las stats entre ERA, W-L, K, SV y AVG, HR, RBI, SB; la evaluación y el crecimiento siguen lo que hizo ese día.

Texture Studio: Escalar con IA (elige una categoría o una textura y la escala ×2 o ×4 en tu tarjeta con Real-ESRGAN y AnimeSharp; la primera vez descarga el motor y el modelo de sus autores) y Pack de Dolphin... (importa packs de texturas de Dolphin tal cual: los nombres son los mismos).

Corregido: el History de MLB Life ya no se cuelga con un pack de temporada activo.

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.5.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de una versión anterior, copia UserData\NAND, UserData\ModSaves y la carpeta mods de la instalación vieja a la nueva.

Problemas conocidos: las dos vías son nuevas y experimentales (turno fijo de cinco partidos que no sigue el cansancio; «solo pitcher» no juega los otros días; un bateador con habilidad de pitcher aún no puede ser dos vías); se probó sobre todo en una PC; Copy/Paste/Import/Export no funcionan todavía con el Wii Remote; los estadios nuevos solo salen en Exhibición; a veces se cuelga al arrancar.

v0.1.4.1 beta — Controller fix

Hotfix for v0.1.4. Windows 10/11 x64.

Fixed

• Controllers did not work in v0.1.4. No button reached the game, so it stayed on the demo and the "You can use the following Controllers" screen. A build step bound the game's controller reading to the wrong place; controllers work again, as in v0.1.3. Thanks for the quick report.

Nothing else changed: this is v0.1.4 with only this fix. Everything new in v0.1.4 (real MLB schedules, Season Editor, DH in both leagues, 15/15 leagues, player passwords) is described in the v0.1.4 notes.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.4.1.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy, then INSTALL and PLAY.

Coming from v0.1.4 or older: after installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

About the controller settings: the Wii "+" button is START in the remapping list (the game sees a GameCube controller). If a controller still shows up as a Wii Remote after unchecking the Wii Remote option, please tell us in the issue, with your controller model.

Corrección de la v0.1.4.

• Los controles no funcionaban en la v0.1.4. Ningún botón llegaba al juego, así que se quedaba en el demo y en la pantalla «You can use the following Controllers». Un paso del armado enganchaba la lectura del control del juego en el lugar equivocado; los controles vuelven a funcionar como en la v0.1.3. Gracias por el aviso rápido.

No cambia nada más: es la v0.1.4 con solo este arreglo. Lo nuevo de la v0.1.4 está en sus notas.

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.4.1.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de una versión anterior, copia UserData\NAND, UserData\ModSaves y la carpeta mods de la instalación vieja a la nueva.

En los ajustes de controles, el botón «+» del Wii es START en la lista (el juego ve un mando de GameCube).

v0.1.4 beta — Real MLB schedules, DH and 15/15 leagues, player passwords

Beta. Expect bugs. Windows 10/11 x64 (Linux and Steam Deck: build it yourself, see below). Thanks to everyone who tried v0.1.3 and asked for these.

📸 More details and screenshots of everything new (Season Editor, real schedules, DH, 15/15 leagues, player passwords) and how it was done: Progress update #3 in Discussions.

What's new

• Real MLB schedules in Season mode and MLB Life (experimental). The new Season Editor (launcher: SETTINGS > TOOLS > SEASON EDITOR) downloads the real major-league schedule of any year from 2002 to 2026 (not 2020) into a mod, shows it month by month by team, and sets which year a new game starts in. The game plays those games on those dates; a season moves to the next year's schedule when the year rolls over. The All-Star Game goes to that year's real break (it is always a Tuesday in mid-July; the game put it on the third Tuesday, on top of real games). See docs/en/season-studio.md.
• Start in any year (start_year): a new Season or MLB Life game can start in 2026 instead of 2008, with the calendar, the draft, paydays and players' ages following it (roster_year sets which year the roster is from, so ages come out right with modded rosters). In MLB Career the birth-date picker offers the matching years (2000 and later).
• DH in both leagues (experimental): SETTINGS > ENHANCEMENTS > DH IN BOTH LEAGUES, or dh = "both" in a mod. Season mode and MLB Life; Exhibition is unchanged.
• 15 and 15 leagues (experimental): SETTINGS > ENHANCEMENTS > 15 AND 15 LEAGUES, or [divisions] in a mod: Houston plays in the AL West, with a 162-game schedule in today's format. The game's own Custom League screen (Season > Start) accepts it too.
• A mod can also say "original" for its DH and leagues, to keep what the Wii game does.
• Success players as text, files or with a controller. On My Data > Password Display, COPY puts a player's 156-character password on the clipboard and EXPORT saves it as a file named after the player. On Password Input, PASTE and IMPORT load one. No more copying passwords from a photo. With a controller: X and Y, and Import shows a list you move through with the D-pad. The buttons are drawn in the game's style. See docs/en/modding-guide.md.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.4.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL (about 4–5 minutes on a 12-thread CPU), then PLAY.

Coming from an older version? After installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

Real schedules, the start year, DH and 15/15 apply to new Season and MLB Life games; games already started stay as they were. The Blender stadium add-on is unchanged (powerpros_stadium-0.8.2.zip, attached again).

Known issues

• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500).
• The Season Editor is new and has not been tried on Linux yet.
• Copy / Paste / Import / Export use a mouse or a GameCube-style controller; not the Wii Remote yet.
• Season mode past 10 seasons: the farewell after season 20 still says "10 years", "Annual Results" has no year title after 2017, and archived years have no screen yet.
• New stadiums appear only in Exhibition.
• The game can occasionally hang at startup: close it and open it again.

If something goes wrong, please open an issue with your CPU, GPU and UserData\Logs\<latest>\console.log; for Season mode, your save helps a lot.

📸 Más detalles y capturas de todo lo nuevo (Editor de temporada, calendarios reales, DH, ligas de 15 y 15, contraseñas de jugadores) y de cómo se hizo: Progress update #3 en Discussions.

Novedades:

• Calendarios reales de MLB en el modo Temporada y en MLB Life (experimental). El nuevo Editor de temporada (launcher: AJUSTES > HERRAMIENTAS > EDITOR DE TEMPORADA) descarga el calendario real de las Grandes Ligas de cualquier año de 2002 a 2026 (menos 2020) en un mod, lo muestra mes a mes por equipo y elige en qué año empieza una partida nueva. El juego juega esos partidos en esas fechas y, al cambiar de año, pasa al calendario del año siguiente. El Juego de Estrellas va al descanso real de ese año (siempre un martes a mediados de julio; el juego lo ponía el tercer martes, encima de partidos reales).
• Empezar en cualquier año (start_year): una partida nueva de Temporada o MLB Life puede empezar en 2026 en vez de 2008, y el calendario, el draft, los pagos y las edades lo siguen (roster_year dice de qué año es el roster, para que las edades salgan bien con rosters de mods). En MLB Career el selector de fecha de nacimiento ofrece los años que tocan (2000 en adelante).
• DH en ambas ligas (experimental): AJUSTES > MEJORAS > DH EN AMBAS LIGAS, o dh = "both" en un mod. Temporada y MLB Life; Exhibición no cambia.
• Ligas de 15 y 15 (experimental): AJUSTES > MEJORAS > LIGAS 15 Y 15, o [divisions] en un mod: Houston juega en el Oeste de la Americana, con un calendario de 162 partidos al formato actual. La pantalla Custom League del juego (Season > Start) también lo acepta.
• Un mod puede decir "original" en su DH y sus ligas, para dejarlos como en la Wii.
• Jugadores de Success como texto, archivo o con control. En My Data > Password Display, COPY copia la contraseña de 156 caracteres al portapapeles y EXPORT la guarda en un archivo con el nombre del jugador; en Password Input, PASTE e IMPORT la cargan. Ya no hay que copiarla de una foto. Con control: X e Y, e Import muestra una lista que se recorre con la cruceta. Los botones tienen el estilo del juego.

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.4.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de una versión anterior: después de instalar, copia UserData\NAND y UserData\ModSaves (tus partidas) y la carpeta mods de la carpeta MLB Power Pros 2008\Game vieja a la nueva, y luego borra la instalación vieja. Los calendarios, el año de inicio, el DH y el 15 y 15 valen para partidas nuevas.

Problemas conocidos: se probó sobre todo en una PC; el Editor de temporada aún no se probó en Linux; Copy/Paste/Import/Export no funcionan todavía con el Wii Remote; con más de 10 temporadas siguen los detalles de la v0.1.3; los estadios nuevos solo salen en Exhibición; a veces se cuelga al arrancar.

v0.1.3 beta — Season mode past 10 seasons, Linux and Steam Deck

Beta. Expect bugs. Windows 10/11 x64 (Linux and Steam Deck: build it yourself, see below). Thanks to everyone who tried v0.1.2 and reported back.

What's new

• Season mode past 10 seasons (experimental). The Wii game ends Season mode after 2017. In the launcher, SETTINGS > ENHANCEMENTS > SEASONS can now be 20 (to 2027) or No limit (never ends; the game keeps the 20 most recent years). It stays at 10 (original) unless you change it. Tested by simulating a whole season in 2029 with real games, through the postseason and World Series, into 2030: standings, finances, the draft, awards, the calendar and its real year, and save and load. Past the original 10 years several of the game's tables had to be extended (finances, team records, the luxury tax, the calendar's year), so please tell us if anything looks wrong.
• New ENHANCEMENTS tab in the launcher, for everything the Wii game does not have. Each option starts as on the Wii; the ones still being tried are tagged EXPERIMENTAL.
• Saves on a new install fixed. With a fresh install and no mods, saving said "Save failed" (the game expects its save folder to exist already, as on a console). Found by the Linux port; thanks @CalenCyr.
• Roster editor (PowerUp+): 2008's extra skin tone. The tone 2008 added is offered as 2.5 (2008), between 2 and 3, and exports to the game. Re-import the 2008 roster to give it back to the 27 players who have it. Asked for on Reddit.
• Linux and Steam Deck (experimental, community contribution by @CalenCyr): a native build made on your own PC from your copy of the game with tools/linux/build.sh, including a portable build for the Steam Deck. 60 FPS on a Fedora PC and on a Deck in the test match. See docs/en/linux.md. The Linux and SteamDeck kits attached here are this repository plus a one-command installer (install.sh / install-steam-deck.sh); as on Windows, they hold nothing from the game: it is built from your disc on your machine.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.3.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL (about 4–5 minutes on a 12-thread CPU), then PLAY.

Coming from an older version? After installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

The Blender stadium add-on is unchanged (powerpros_stadium-0.8.2.zip, attached again).

Known issues

• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500).
• Season mode past 10 seasons: the farewell after season 20 still says "10 years" (fixed game text), "Annual Results" has no year title after 2017 (the game only has those pictures), and archived years (past the latest 20) are kept in the save but there is no screen to view them yet.
• New stadiums appear only in Exhibition.
• The game can occasionally hang at startup: close it and open it again.

If something goes wrong, please open an issue with your CPU, GPU and UserData\Logs\<latest>\console.log; for Season mode, your save helps a lot.

Beta. Puede tener errores. Windows 10/11 de 64 bits (Linux y Steam Deck: compílalo tú, ver abajo).

Novedades:

• Modo Temporada más allá de 10 temporadas (experimental). En la Wii, el modo Temporada acaba en 2017. En el launcher, AJUSTES > MEJORAS > TEMPORADAS puede ser ahora 20 (hasta 2027) o Sin límite (no acaba nunca; el juego guarda los 20 años más recientes). Sigue en 10 (original) si no lo cambias. Probado simulando una temporada entera en 2029 con partidos reales, con la postemporada y la Serie Mundial, hasta 2030: clasificación, finanzas, draft, premios, el calendario con su año real, y guardar y cargar. Pasados los 10 años originales hubo que ampliar varias tablas del juego (finanzas, registros de equipos, impuesto de lujo, año del calendario): avísanos si ves algo raro.
• Pestaña MEJORAS en el launcher, para todo lo que el juego de la Wii no tiene. Cada opción empieza como en la Wii; las que aún se están probando llevan la etiqueta EXPERIMENTAL.
• Arreglado guardar en una instalación nueva. Con una instalación limpia y sin mods, guardar decía «Save failed» (el juego espera que su carpeta de partidas ya exista, como en la consola). Lo encontró el port a Linux; gracias, @CalenCyr.
• Editor de rosters (PowerUp+): el tono de piel extra de 2008. El tono que añadió 2008 sale como 2.5 (2008), entre el 2 y el 3, y se exporta al juego. Vuelve a importar el roster de 2008 para que lo recuperen los 27 jugadores que lo tienen. Lo pidieron en Reddit.
• Linux y Steam Deck (experimental, contribución de @CalenCyr): una compilación nativa hecha en tu PC desde tu copia del juego con tools/linux/build.sh, incluida una compilación portable para la Steam Deck. 60 FPS en un PC con Fedora y en una Deck en el partido de prueba. Los kits Linux y SteamDeck de esta release son el repositorio con un instalador de un comando (install.sh / install-steam-deck.sh) y no traen nada del juego. Ver docs/linux.md.

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.3.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de una versión anterior: después de instalar, copia UserData\NAND y UserData\ModSaves (tus partidas) y la carpeta mods de la carpeta MLB Power Pros 2008\Game vieja a la nueva, y luego borra la instalación vieja.

Problemas conocidos: se probó sobre todo en una PC; con más de 10 temporadas, la despedida tras la temporada 20 sigue diciendo «10 years», «Annual Results» no tiene título de año pasado 2017 y los años archivados se guardan pero aún no hay pantalla para verlos; los estadios nuevos solo salen en Exhibición; a veces se cuelga al arrancar.

v0.1.2 beta — commentary fix, saves in use, stadium tools

Beta. Expect bugs. Windows 10/11 x64 only. Thanks to everyone who tried v0.1.1 and reported back.

What's new

• Commentary no longer breaks when the window is hidden. On Windows 11, while the game's window was minimized or covered by another window, Windows slowed the game's timers down, and the commentator and PA could play wrong or broken lines for a while. The game now asks Windows not to do that.
• See which saves are in use. Roster mods keep their own saves, so a season started with one roster never mixes with another. Switching mods could make your saves look gone. In the launcher, MODS now starts with SAVES IN USE (Normal, or the roster mods that are on); press it to open that save folder. Switching a roster mod on or off tells you that set has its own saves and the others stay saved. Nothing is ever deleted.
• Sharper textures and anti-aliasing. The game's textures get mipmaps generated on load (cleaner at a distance), and there is a new ANTIALIASING option (VIDEO tab).
• Bigger custom stadiums. Stadium packs up to 80 MB now load (about 21 MB before).
• Blender stadium add-on 0.8.2 (powerpros_stadium-0.8.2.zip):
  • View in game: opens the game straight into the stadium you are making, with a free camera and the real match cameras. Key C draws the stadium's collision over the picture, coloured by kind, with a box per kind to show or hide it.
  • New stadium from scratch: build a stadium with no base stadium: each object gets a role (ground, stand, fence, crowd with the game's animated people, flags that move with the wind, transparent, glow). The game's bases, plate and mound come in place.
  • Collision by kind: fences, stands, foul poles, invisible walls… each in its own object, named and coloured, and Make collision turns any mesh into collision.
  • HD textures, menu photo, textures painted over plain faces kept, and several fixes.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.2.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL (about 4–5 minutes on a 12-thread CPU), then PLAY.

Coming from an older version? After installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

Known issues

• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500).
• New stadiums appear only in Exhibition.
• Season mode still ends after 10 seasons (being worked on).
• The game can occasionally hang at startup: close it and open it again.

If something goes wrong, please open an issue with your CPU, GPU and UserData\Logs\<latest>\console.log.

Beta. Puede tener errores. Solo Windows 10/11 de 64 bits.

Novedades:

• El comentario ya no se rompe con la ventana oculta. En Windows 11, con la ventana del juego minimizada o tapada por otra, Windows frenaba los temporizadores del juego y el narrador y el locutor podían decir frases equivocadas o cortadas un rato. Ahora el juego le pide a Windows que no lo haga.
• Qué partidas se están usando. Los mods de roster tienen sus propias partidas, para que una temporada empezada con un roster no se mezcle con otro. Al cambiar de mods podía parecer que tus partidas habían desaparecido. En el launcher, MODS empieza ahora con PARTIDAS EN USO (Normales, o los mods de roster activos); al pulsarla se abre su carpeta. Al activar o desactivar un mod de roster te avisa de que ese conjunto tiene sus propias partidas y de que las otras siguen guardadas. Nunca se borra nada.
• Texturas más nítidas y antialiasing. Las texturas del juego reciben mipmaps al cargar (más limpias de lejos) y hay una opción nueva, ANTIALIASING (pestaña VIDEO).
• Estadios propios más grandes: cargan packs de estadio de hasta 80 MB (antes, unos 21 MB).
• Complemento de Blender 0.8.2 (powerpros_stadium-0.8.2.zip): «Ver en el juego» con cámara libre y las cámaras del partido (tecla C: la colisión del estadio por colores, con una casilla por tipo); estadios desde cero con un papel por objeto (público animado del juego, banderas con viento…); colisión por tipo, con nombre y color, y «Convertir en colisión» para cualquier malla.

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.2.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de una versión anterior: después de instalar, copia UserData\NAND y UserData\ModSaves (tus partidas) y la carpeta mods de la carpeta MLB Power Pros 2008\Game vieja a la nueva, y luego borra la instalación vieja.

Problemas conocidos: se probó sobre todo en una PC; los estadios nuevos solo salen en Exhibición; el modo Temporada sigue acabando a las 10 temporadas (en ello); a veces se cuelga al arrancar.

v0.1.1 beta — true 16:9, fill screen, frame interpolation

Beta. Expect bugs. Windows 10/11 x64 only. Thanks to everyone who tried v0.1.0 and reported back.

What's new

• True 16:9. The game now really draws in widescreen. In v0.1.0 it always drew 4:3, and "Force 16:9" only stretched that image (round things looked oval). Fixed by answering the game's widescreen query (SCGetAspectRatio) from the video settings.
• Fill screen (no black strips). The game draws its image inside a black border at the top and bottom. On a CRT TV that edge was hidden; on a monitor it showed up as two black strips. The new FILL SCREEN option (VIDEO tab, on by default) cuts that border off, so the image fills the window. On a 16:9 screen the image ends up 8% taller than on the Wii; turn it off if you prefer the exact proportions.
• Frame interpolation (experimental). FRAME INTERPOLATION (VIDEO tab): No / 120 / 180 FPS. The game still runs at 60 and the in-between images are generated for 120 Hz+ screens. On a Radeon RX 5500 at 1x, 120 FPS took the GPU from about 30% to 55%, and 180 FPS to 65%. Fast motion may show glitches; please report what you see.

Install / update

1. Download MLB-Power-Pros-2008-Setup-v0.1.1.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL (about 4–5 minutes on a 12-thread CPU), then PLAY.

Coming from v0.1.0? After installing, copy UserData\NAND and UserData\ModSaves (your saves) and the mods folder from the old MLB Power Pros 2008\Game folder into the new one, then delete the old install.

The Blender stadium add-on is unchanged (powerpros_stadium-0.4.0.zip, attached again). Everything else is as in v0.1.0, including the recommended roster and uniform mods.

Known issues

• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500).
• One player hears the commentator and PA play wrong or broken lines after the first inning; not reproduced yet. If it happens to you, please open an issue with your CPU, GPU and UserData\Logs\<latest>\console.log.
• New stadiums appear only in Exhibition, and the walls generated for them don't follow the visible stands yet.
• The game can occasionally hang at startup: close it and open it again.

Beta. Puede tener errores. Solo Windows 10/11 de 64 bits.

Novedades:

• 16:9 real. Ahora el juego dibuja de verdad en panorámico. En la v0.1.0 siempre dibujaba en 4:3 y «Forzar 16:9» solo estiraba esa imagen.
• Llenar pantalla (sin franjas negras). El juego dibuja su imagen dentro de un borde negro arriba y abajo, que en una tele de tubo no se veía. La opción LLENAR PANTALLA (pestaña VIDEO, activada por defecto) lo recorta y la imagen ocupa toda la ventana. En una pantalla 16:9 queda un 8 % más alta que en la Wii.
• Interpolación (experimental). INTERPOLACIÓN (pestaña VIDEO): No / 120 / 180 FPS. El juego sigue a 60 y se crean imágenes intermedias para pantallas de 120 Hz o más. Pide más GPU y puede verse algún defecto en lo que se mueve rápido.

Instalar o actualizar: descarga MLB-Power-Pros-2008-Setup-v0.1.1.zip, descomprímelo, abre MLBPowerPros2008-Setup.exe, elige tu disco y pulsa INSTALAR. Si vienes de la v0.1.0: después de instalar, copia UserData\NAND y UserData\ModSaves (tus partidas) y la carpeta mods de la carpeta MLB Power Pros 2008\Game vieja a la nueva, y luego borra la instalación vieja.

Problemas conocidos: se probó sobre todo en una PC; un jugador oye frases equivocadas o cortadas del narrador después del primer inning (sin reproducir; si te pasa, abre un issue con tu CPU, GPU y console.log); los estadios nuevos solo salen en Exhibición; a veces se cuelga al arrancar.

v0.1.0 beta — first release

First release (beta). Expect bugs. Windows 10/11 x64 only.

MLB Power Pros 2008 (Wii, USA, RL8E54) as a native PC program: the game's PowerPC code is translated to C++ and compiled on your PC from your copy of the game. No emulator, and nothing from the game is included in this download.

Install

1. Download MLB-Power-Pros-2008-Setup-v0.1.0.zip and unzip it into a folder of yours (not Program Files).
2. Open MLBPowerPros2008-Setup.exe, press CHOOSE DISC and pick your copy (ISO, NKit, RVZ, WBFS, WIA, GCZ or CISO).
3. Press INSTALL. It checks that the image is a clean RL8E54 dump, extracts it, translates the code and compiles it: about 4–5 minutes on a 12-thread CPU.
4. Press PLAY. You need about 2.5 GB free (900 MB for the Setup, 1.5 GB for the installed game).

What's in it

• 60 FPS on Direct3D 12 or Vulkan; internal resolution up to 4x, AMD FSR 1, anisotropic filtering up to 16x, quality presets.
• Any controller through SDL3 (DualSense, Xbox…) or keyboard and mouse, Dolphin-style remapping, up to 4 players.
• A launcher before each session for video, audio, controls, mods and tools. The launcher, Setup and tools are in English and Spanish.
• Rosters: bundled PowerUp+ editor adapted to 2008 (import and export 2008 rosters). Players enter as native players or keep their edited flag; roster mods reach MLB Life, and their saves are kept apart.
• Textures: Power Pros Wii 2008 Texture Studio. Export any texture to PNG and replace it, same size or HD; it can also capture what you see in the game.
• Stadiums: Blender add-on powerpros_stadium-0.4.0.zip (attached; Blender 4.2+ → Edit → Preferences → Get Extensions → Install from Disk). Import any stadium with textures and collision, edit it and export it as a mod or as a new stadium in Exhibition.

Recommended mods (not included — get them from their authors)

The release can't ship game data, so these come from their original sources:

• Updated rosters (2025/2026): no download needed. Launcher → SETTINGS → TOOLS → ROSTER EDITOR → Generate Roster (real MLB rosters from the MLB Stats API), then Export Roster → MLB Power Pros 2008 Mod. Unzip the zip into the game's mods\ folder and enable it in MODS. Choose native or edited players in TOOLS → ROSTER PLAYERS.
• Updated uniforms and logos: Sir Dropshot's MLB Uniforms and Logos Dolphin texture pack (download, listed at 30-30.club). Create mods\<name>\textures\, copy the PNGs from the pack's RL8E54 folder into it, and enable it in MODS. Dolphin texture packs for RL8E54 work unchanged.

Known issues

• Tested mainly on one PC (Ryzen 5 5500 + Radeon RX 5500), installed clean in Spanish and English.
• New stadiums appear only in Exhibition (not in Season, League or MLB Life), and their "Home of the…" line is the base stadium's.
• 4x is close to 4K and heavy for mid-range GPUs; "Match window" is recommended.
• The game can occasionally hang at startup: close it and open it again.
• riivolution/ mods are untested. Discord Rich Presence stays off until it has its own application ID.

Report bugs in Issues with your GPU, your controller and what you were doing.
