It's been too long, hasn't it? This is the Competition Mode in Sonic 3C Delta, which is one area of the hack that is nearly finished. As such, I thought it'd be a deserving candidate for an update video (after 4 months!) My sister and I played through the Grand Prix, but there's a slew of differences in each of the zones - can you spot them all?
Unfortunately, it seems like YouTube's compression has caused odd frame skips and such at certain points in the video. This wasn't an issue in the original recording.
Sonic 3C Delta is a hack of Sonic 3 that works like a complete version of the 1103 prototype. It is a mashup of early/unused content for Sonic The Hedgehog 3, and includes features such as a playable prototype Knuckles, prototype inspired S&K Zones, prototype music, and plenty more. None of this would have been possible without the dedicated efforts of the Sonic 3C Delta team:
Chainspike/Silver Sonic 1992 - Project leader, Main Programming.
Mecha Knuckles 2001 - Co-leader, Main Sprite Artist, Beta Tester.
sonic c32ttb1 - Beta Tester, Suggestions.
EmmaNerd - Main Sprite Artist, Suggestions, Beta Tester.
Zummone - Programming, Art Direction, Suggestions.
Inferno - Sound Driver Porting, Beta Tester, Suggestions.
SunBun - Sprite Artist, Beta Tester, Suggestions, Layout Designer.
GigglyMan - Beta Tester, Suggestions.
Coil - Beta Tester, Suggestions.
Xebninmaj Sark - Beta Tester, Suggestions.
Special thanks also goes to Hexagonal, mcginnis03, and MrSonicSMSSpriter for some sprites used.
