i have other thoughts on your games at hand, but i'm going to avoid the obvious since you left that pretty clean...
your story is kinda crazy trying to understand exactly...now a "mms" stands for a magic memory stick, if you kept formatting it, it wasn't a mms anymore, that's 1.
2. when you put the games on that stick and played them on 2 different psp's, it made clicking sounds on both and went black...so my somewhat conclusion to this, it's a bad memory card you're using, you can try reflashing it but if that card is doing it to 2 different psp's, gotta be the card or you're "backup copies" of *cough, cough* your games, are ripped bad.
