Sonic games (Sonic 1, 2, 3&K) are delisted from this collection thanks to a genius marketing strategy. This product is now outdated and is only worth your time if you played other Sega Genesis games in the 90s
If you bought them earlier you can still access and play them

UPDATE 07.11.24: Well ♥♥♥♥, next month 06.12 the ENTIRE emulator, including all of the games are getting delisted. Talk about games preservation, a ♥♥♥♥ move from a lazy ass company. Maybe this game would still have any audience if sonic games weren't delisted?
