Sonic the Hedgehog: Sonic1 Spike Bug Fix & Spindash is a ROM hack for the Sega Genesis that addresses the spike bug from the original Sonic the Hedgehog game while introducing a refined spin dash mechanic reminiscent of later titles in the franchise. The update features an animation during the spin dash, though it lacks the accompanying dust effect found in subsequent games.
This is a hack which fixes the spike bug and also implements a near perfect rendition of the spin dash. There is an animation while doing the spin dash like in the later games. The only thing missing is the dust underneath.
Special thanks to Lightning & FraGag for their guides on how to implement this.
For some reason it doesn't like opening in a level editor, I don't know why. However, if you decompress the original Sonic 1 and decompress this ROM, you can open those decompressed original Sonic 1 files, then after you edit them, recompress them into the edit… I think.
The patch is in xdelta format due to copyrighted data being part of the original IPS patch.
