Sound ID | Audio | Name | Notes |
---|---|---|---|
$99 | Title Screen | Still uses the theme from Sonic 1. | |
$8A - $8B | Stage Select/Drowning | The snare sample has been replaced with a kick, and the trumpet sample is heavier. A backing trumpet in the left channel is instead a celesta. The right channel has an extra bottle-like instrument. | |
$87 | Neo Green Hill Zone (Aquatic Ruin Zone) | The instrumentation is heavier and lacks a backing part in the left channel. | |
$8D | Chemical Plant Zone/Genocide City Zone | About 1.4% slower than the final, and the first pitch bend before the loop comes in late. | |
$96 - $97 | Hill Top Zone | About 11.35% slower, and the harmonica-like instrument sounds slightly different. | |
$82 | Green Hill Zone (Emerald Hill Zone) | About .3% slower, and some of the percussion is more distinct. | |
$83 | Wood Zone/Metropolis Zone | About 1.6% slower. The instrumentation is radically different, with more grating and off-key tones. Also uses a different off-beat sample, and the melody has a simpler, downward pitch bend. | |
$86 | Hidden Palace Zone (Mystic Cave 2-Player) | About .6% faster. The intro has more quavery instruments, and the mix is overall less full. | |
$81 | Oil Ocean Zone (Casino Night 2-Player) | About 10.75% slower. | |
$90 - $91 | Sand Shower Zone (Oil Ocean Zone) | About 8.35% slower. Has more distinctive intro instrumentation, and some backing instrument samples are slightly different. | |
$85 | Dust Hill Zone (Mystic Cave Zone) | About 6.6% slower. | |
$84 | Casino Night Zone | About 12.93% slower. The instrumentation is much different, giving a sleazier feel. The percussion and bass are much more ornamented. The prototype has an extra harmony line just before the loop. | |
$8F | Rock World Zone (Sky Chase Zone) | About 6.95% slower, and has a louder bell sample. | |
$92 | Unused (Wing Fortress Zone) | About 6.23% slower. The backing instruments are slightly altered and much louder, sometimes to the point of almost drowning out the melody. | |
$88 | '100 Rings' Extra Life (Death Egg Zone) | About 15.65% faster, and has much fainter and sicklier instrumentation, plus completely different percussion. The main instrument also sounds like when you collect a ring. | |
$9A | Act Complete | Seems to have a very slight jump in the first two notes that the final doesn't. | |
$8E | Dr. Eggman | About .25% slower. Has a much heavier mix, and a faint additional backing part. | |
$8C | Unused (Final Boss) | About 1% slower. Has a different, less distinct kick sample. | |
$95 | Invincibility (Super Sonic) | About 7.4% slower. The right channel has an extra 'alarm' instrument in the intro. This was later replaced with a different theme and became the music for Super Sonic. | |
$94 | Unused (2-Player Results) | About 1.5% slower. | |
$93 | Blue Lake Zone (Emerald Hill 2-Player) | About 6.64% slower. Has a slightly shorter kick sample. | |
$89 | Unused (Special Stage) | Has a very slightly more prominent kick sample. |
Graphic | Offset | Compression | Description |
---|---|---|---|
0x28A6A | None | Animated drill tiles for use in Metropolis Zone. These are loaded to slots 368-377 in VRAM, though the game mistakenly loads two copies of the horizontal drill instead of the vertical drill. | |
0x77472 | Nemesis | This is the vine that acts as a switch in Mystic Cave Zone. It has not yet been coded at this point. | |
0x7756A | Nemesis | The hanging vine from Mystic Cave Zone. It hasn't been coded, either. | |
0x4E8A6 | None | These graphics are leftovers from Chiki Chiki Boys. This probably resulted from the process of compiling and burning ROMs onto EPROM chips. | |
0x4B76C | None |
