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.
