v0.1.0-beta.3

The three Street Fighter III games in one app, and online play through its own service.

An unofficial native port of Capcom's three Street Fighter III arcade games (CPS-3): 3rd Strike, New Generation and
2nd Impact, in one launcher. No game is included: you need your own ROM sets
(which ones).

Download

Your system	Download
macOS 13 or later, Apple silicon or Intel	SF3comp-macOS.zip
Windows 10 or 11, 64-bit	SF3comp-windows-x64.zip
Linux x86_64, Steam Deck, Steam Machine	SF3comp-linux-x86_64.tar.gz

Install

macOS

1. Open the zip: it gives SF3comp.app. Move it to your Applications folder. (The app of an earlier version,
   Street Fighter III 3rd Strike.app, can go to the Trash: its ROM set, settings and saves are kept.)
2. The app is not notarized by Apple, so the first time: right-click it and choose Open, then Open. If
   macOS only offers Done or Move to Trash, choose Done, then open System Settings → Privacy &
   Security, scroll down and press Open Anyway.
3. In the launcher, Choose folder… and show it the folder your ROM sets are in (sfiii3nr1.zip, sfiiin.zip,
   sfiii2n.zip, and sfiii3n.zip for 3rd Strike's later revision: as many as you have), or drop a set on the launcher. Press a game's Play.

Windows

1. Right-click the zip, choose Extract All…, and extract it to a folder of your own (for example
   Documents\Games).
2. In the SF3comp folder, open sf3comp-launcher.exe. The programs are not signed, so the first time Windows
   may say it protected your PC: press More info, then Run anyway.
3. Choose your ROM sets as above, and press a game's Play.

Linux, Steam Deck and Steam Machine

1. Unpack it where it can stay: tar xzf SF3comp-linux-x86_64.tar.gz -C ~/Applications (on a Steam Deck, in
   Desktop Mode: right-click the file in Dolphin, Extract → Extract archive here).
2. Run SF3comp/sf3comp-launcher. It needs only an X11 or Wayland desktop and the usual sound libraries (SDL 3
   is built in).
3. Choose your ROM sets as above. Add to Steam on a game's page puts it in your Steam library (under
   Non-Steam) for Game Mode.

In the game, Esc or F1 (on a gamepad, a click of the left stick, or Start and Select together) opens the in-game
menu. Your settings, save states and each board's settings memory are in your own user folder, a folder for each game;
the ROM sets are only read.

Coming from a version before the three games were one download (0.1.0-beta.2 and earlier): 3rd Strike keeps its
folder, so its settings, saves and the ROM set you chose are as you left them. The launcher is now
sf3comp-launcher (the old sfiii3-launcher can be deleted); a Steam shortcut made by the old launcher starts
the old launcher, so make it again from the new one.

What's new in 0.1.0-beta.3

• Online play has its own service (online/, sf3comp-online), no longer cps2recomp's: codes, the lobby and the
  waiting room are this collection's alone, with a stats page for whoever runs it. Both players need this build or
  later; an older one still finds only the old service's lobby.

• Stage on the menu's first page, in every game: one choice of where the next fight is, in the arcade game,
  training and the modes that have no stage of their own to say (3rd Strike: its own stages and the other games').
  It replaces the Training page's Stage row and the Display page's "Stages (experiment)". Online, the host's choice.

• Guest stages in the modes (3rd Strike): the tag team battle's and the endless battle's Stage rows have New
  Generation's and 2nd Impact's stages too, as training's Stage row has them (they had 3rd Strike's only).

• New defaults (the Enhanced preset, and Reset all options): arcade timing, invisible walls in widescreen, and
  Scaling's whole-pixel choice, now called Integer. A player whose settings already say otherwise keeps them.

• Widescreen: the black screen before a round (and the striped wipes either side of it) left the added columns at the
  left uncovered. The text layer, which the game fills for them, now wraps into those columns as it does on the board.

• 3rd Strike's later revision (990608, sfiii3n) as a game of its own in the launcher, with training mode,
  widescreen, online play and replays. The definitive version stays the 990512 one.

• Input lag readout (Display page): the frames the game itself takes to show a press (measured in a fight),
  what run-ahead takes off, the port's own time from the press to handing the frame to the screen, and the sum.

• Training scenario: Evo Moment 37 (3rd Strike): Ken with a sliver of health against Chun-Li's super art, every
  try by itself; the readout counts the parries and says where a try ended.

• Red parry drill (3rd Strike): a score of the strings you guarded and then parried out of.

• Hit confirm drill (training, all three games): the dummy guards at random and each attack that touches it is
  judged by what you did next (gone on after a hit, held back after a guarded one), with a running score.

• Match replays. Every match, offline or online, is kept (the latest 40) and listed on the in-game menu's Replays
  page: watched again with the readouts and hit boxes, stopped, stepped, slowed, gone back and forward in, and played
  on from any moment with Start (the restart key goes back to that moment). In all three games.

• SF3comp: the three Street Fighter III games in one app. New Generation and 2nd Impact play as games of their own
  beside 3rd Strike, picked in one launcher (SF3comp.app, sf3comp-launcher), each with training mode, widescreen
  and online play with rollback. 3rd Strike's settings, saves and ROM set carry over from the single-game launcher.
  Where a far background layer's art ends short of the wider picture at a stage's end, its own end is shown again,
  mirrored. Hit boxes sit on the fighters' pictures (they were a frame early).

• The launcher finds ROM sets in a rom folder beside it, and shows 3rd Strike as "Street Fighter III 3rd Strike
  Definitive" (its folder of settings and saves is the one it had).

• Board page: each setting now sets its own (Difficulty set the damage level and Damage level the difficulty, Timer
  speed did nothing, and the rounds, Event and Bonus games were crossed).

• Stage viewer: New Generation's and 2nd Impact's stages, each with its own music; "Q's" gone (Q has no stage of his
  own: it showed Dudley's). On one stage it stays on it.

• Widescreen: switched in the in-game menu, the window takes the 16:9 shape as it does when started so (it stayed 4:3,
  the picture letterboxed in it); the stages' things no longer pop in 64 columns inside the picture's edges.

• The open source project: a new README, CONTRIBUTING, CODE_OF_CONDUCT and SECURITY, issue and pull request
  templates, the files' audit (tools/audit.sh), CI on macOS, Linux and Windows (the programs built with no
  translated code and started with no window: tools/ci_smoke.sh), and a release workflow that drafts a release from
  a tag (docs/RELEASING.md).

• Sound in stereo: the board set to its EXTERNAL (stereo) output, not JAMMA (mono), its default. In mono the knock-out's
  boom, made of one voice for each side, played twice on both, twice as loud, flanged and clipping. The Board page's
  Sound row picks mono again.

• Readable code: the fighters' moves (the step in a fight, the hit stop, where a move may be cancelled, the dispatch
  into normal moves, specials, super arts and throws) and the animations' frames and boxes are written again as C++,
  each checked against the game's own code on every call.

• Bonus games: straight from character select to the bonus stage, as the game itself goes there after a won match
  ("BONUS STAGE", the versus screen, the stage), with no match fought unseen first.

• Guest stages: the camera follows 3rd Strike's across and up on every stage (it followed on some only as the fighters
  neared the picture's edges, on 2nd Impact's Elena stage not at all), Oro's entrance from the sky included, and on
  both Necro stages and the widest ones it is no longer a few columns to one side. Widescreen fills on New
  Generation's stages (a strip showed past their ends).

0.1.0-beta.2

• Guest stages (New Generation's and 2nd Impact's): ROUND 1 and FIGHT! shown over them (they were hidden), the
  opponent's stage there from the round's first frame with "load ahead" off (3rd Strike's own stage showed first), no
  camera pan at a round's start. Tag team battle: the incoming fighter's score is shown at once (it read 00 until the
  next points).
• Readable code: the computer player (how it chooses a plan, answers, guards, parries, gets up, and plays its plans),
  the stage's camera and the versus stage choice, and the fight's score, clock, round end and hit test are written
  again as C++, each checked against the game's own code on every call (checklifts.sh).
• Bonus games (Alternative modes): Crush the Car or Parry the Ball, straight from the menu with the character chosen at
  character select; the menu again when it is over.
• The alternative modes made as the CPS-2 ports have them. Ring out: a fighter knocked about at an open end goes over
  it and falls, and the winner jumps down onto the next stage, the camera following it. Endless battle: the stages
  scroll by with no break (or fade, as a choice). Tag team battle (so named; tag the default; rested fighters keep
  their health). Attract mode with free play on. The stage viewer with only music. The model viewer straight to its
  character, with Reset options and the animation's name at the top. The colour editor's panel: any character, set,
  line and colour, random colours, a library of saved sets.
• The zoom on a fighter works (it had nothing to follow). Custom colours are always on. The endless battle's scroll
  never stops at a stage's end; the model viewer keeps its character in place with nothing else drawn; a mode that is
  over opens the menu on its page instead of starting the board again.
• The menu in the CPS-2 ports' order and words (Alpha 2's, row by row). Endless battle's shuffle fades one stage into
  the next. In a ring out the computer plays the mode: out of its own corner, pushing you to yours. Training's hit
  boxes in widescreen were drawn 64 columns left of the fighters.
• Arcade timing (the Game page, off unless chosen): the processor takes the board's time, its memory's waits, its
  cache's misses and its pipeline's stalls, so the game slows down where the board does. Checked against jotego's
  CPS-3 core simulated: the start-up, the attract mode and a fight, frame by frame.

0.1.0-beta.1

The first version: 3rd Strike (sfiii3nr1, Japan 990512) as translated code on the port's own CPS-3 machine.

• The launcher (game page, Online page, features, controllers) and the in-game menu, save states, free play, the
  CPS-2 ports' display options and shaders, widescreen (or 16:9 played as on the board, with invisible walls).
• Training mode: hit boxes (projectiles too), input display, frame meter, frame data and its log, damage, stun and
  parry readouts; a dummy that guards, parries, escapes throws, quick-stands, mashes out of stun, records and replays,
  or is played by the game; a stage choice; start over in a corner.
  The dummy's While guarding: a red parry.
• Alternative modes: attract mode (everything, the intro only, or the fights only), a stage viewer (any stage, scrolled
  with the stick or by itself, any tune; Infinite: every stage in turn), survival, endless battle (shuffled or
  scrolling stages), ring out, team battle (knock-out or tag: tag in with the left trigger, a jump-in attack, the
  knocked-out lying a while, the team's gauge carried over, a time over to the team with more health; co-op and 2 vs
  2; CPU difficulty and stage), a model viewer (every animation, the stage's front pieces in front or behind), the
  colour editor and custom colours; play as Gill; full gauge cheats.
• Readable rewrites of the round's clock and the damage formula, checked call by call against the game's code.
• Online play with rollback (a code, the lobby, the waiting room).
• A custom soundtrack (by song or as a playlist), and any stage's music for a fight.
• The definitive version's stages: New Generation's and 2nd Impact's, one chosen or each opponent's own, with their
  music (their sets beside 3rd Strike's).

No game files are included: you need your own sfiii3nr1 set (and sfiiin, sfiii2n for the other games' stages). The macOS app is signed ad hoc, not notarized.
