General Changes

The Cutting Room Floor research

This prototype has a research article on TCRF.

• Basic debug mode (L+R in-game).
• Runs at 50fps without any frameskip
• 50/60Hz switcher does not work, the game runs at 50Hz regardless of the setting.
• Uses the final title screen despite being older than the 10.8 build
• Subtitles lack background, and many of the subtitles are unescaped, functioning additive color blending like the Mario Kart: Double Dash! demo build.
• Two Player mode has XBOX HUD Elements, and black bar
• Massive slowdown on 2P splitscreen levels
• Team Chaotix uses Sonic level layouts most of the time, sometimes with functional goal rings
• Audio is a mix of English and Japanese voices
• Only the audio tracks from the E3 and TGS Builds are present (Seaside Hill, Rail Canyon, Bullet Station).
• Unique sound effect for score counter at end.
• Omega uses unfiltered voice clips.
• FMVs show corruption on the bottom of the screen.
• Various missing textures
• Some objects don't use special pixel processing render states.
