Confirmed. Previously the Saved Games mode had a bug that could lock up the game, btw.I just want to confirm something with everybody.
I just gave Sonic Gems Collection a go using r142, and Sonic CD seems to freeze on the 'Now Loading' screen when loading the game. Does anybody else have this problem? If so, I will edit the wiki to reflect this and advise people to emulate the game with a MegaCD emulator instead. I have tried both compressed and uncompressed images.
Everything else in the game works, aside from the GameGear games still having no sound.
It's not the only game recently with crashing, Fire Emblem is now crashing as well.
