There is a project called CD32 CD100. It a compilation wich includes 100 old floppy games on a CD32 CD-Rom. It is very nice, but not all the games runs well with an standard CD32 (the game selector and the music backround eats ram)... on a CD32 expanded with some ram, it should be perfect.
I don't have the link now, but you can find it simply searching into google.
