StF:Remix is a hack of the original arcade version and HD console ports of Sonic the Fighters, including some new features to help give the game a new spin.

Currently at version 3, Remix has a bunch of new features that will help spice things up a bit:

• Honey, Dr. Eggman (mech and mechless forms) and Metal Sonic have all been added to the CSS: They're in invisible slots to the right of Knuckles, and can be picked normally.
• Restored random mode: Hold P1 or P2 punch while pressing start on the title screen, to play random mode, with the unused CSS remixed music restored. You'll be given a randomized set of characters to fight against in story mode, without repeats, including the following extra characters: Honey, mechless Eggman, RoboEgg, Metal Sonic and Super Sonic.
• Alternate character costumes: Press P1 or P2 kick while selecting your character on the CSS. Currently has 5 costumes: Super Sonic, Amy with Honey's attire, alternate color Honey (for Player 1), Cyborg Eggman, Tank Mech Eggman and Rocket Metal Sonic. All five characters with costumes will fight their normal color counterpart instead of a grayscale clone in mirror matches. These alternate costumes double as grayscale alts when playing normally for the 3 characters that don't have one normally.
• No ketchup damage mode: Hold P1 or P2 kick while pressing start on the title screen, to enable no ketchup damage mode. Catchup damage (colloquially known as "ketchup" damage) makes characters take more damage depending on some factors like health lead and such, and this mode allows disabling that.
• Unused music restored: Random mode makes use of the unused CSS music remix, Sunset Town will play on Dynamite Plant if any player is Honey, and Hurry Up! plays in Death Egg's Hangar.
• Random character select button: Holding P1 or P2 barrier/block will cycle through all the characters on the CSS, and releasing it will select. Causes some flickering on a portion of the screen. Don't use if you're suceptible to health issues related to that!
• Other changes: Some miscellaneous bugfixes and unused content restored from the original game, such as the unused ice blocks in Aurora Icefield. The japanese warning screen is now omitted on the arcade version.

Install process for the arcade version:

1. Create an sfight folder on the roms folder of the Model 2 Emulator.
2. Extract an sfight romset zip on the roms/sfight folder of Model 2 Emulator, so all epr/mpr files are stored in it. Make sure to not have the romset zip itself in here!
3. Extract the two replacement epr-19001.15 and epr-19002.16 in the roms/sfight folder and replace the files originally there.
4. Well, start up the emulator and play!

Install process for the PS3/360 ports:

1. Unpack the game container. On 360 you can do this by using wxPirs or Velocity, and on PS3 you can use RPCS3.
2. Go into media, and if on PS3, unpack "rom.psarc" using unpsarc. You should have a folder inside media called "rom". On 360, you'll just have this already.
3. Drop the replacement "rom_code1.bin" included in the zip on the download for consoles here.
4. Load the game on your modded console or emulator, and play!

Known issues:

• The head on the Super Sonic skin will revert back to regular Sonic's head when doing his losing animation. Not sure how to fix this yet.
• Pressing start on the new CSS slots a couple times will crash the console versions. No way around it for the moment, just avoid doing that.
• Enabling character costumes won't instantly reload the whole model. To preview the costume properly you can switch away and then back to your character. This doesn't affect starting the game, you'll always have the proper full model in the match.
