soniNeko is a hack of Sonic the Hedgehog (16-bit) for the Sega Mega Drive/Genesis by nineko. It is notable because of its extended playlist, which not only completely replaces all the songs from the original game, but also introduces several new songs, bringing the grand total to 71 (instead of 22 as in the original Sonic 1); most of those songs are conversions from MIDI and MOD files (as a demonstration of xm2smps/xm3smps capabilities), and a small amount of them are conversions from games that use the Cube/Iwadare sound engine. None of those songs have been converted from other games that use the SMPS sound system, something soniNeko is still unique for.
