SONIC98.nes is unlike any Sonic.exe game you've ever played before, with the NES bootleg aesthetic and Sonic gameplay (albeit bootleggy), so no more walking simulators! Help Tails and the others gather the 7 Chaos Emeralds and rescue Somari so they can defeat the vengeful spirit SONIC.NES and set their souls free!
