^ for Zeromus
Just in boxes, some had the black cover over them and others didn't. I get them out once every in a while and usually I can get all of them to work. It's not like I kept the games and system up there for years.

Is there some thing I can clean my games with? I'm kind of scared to try anything because it might ruin the game even more.

Edit: I'll try the rubbing alcohol, thanks Jowy.
