Shin Megami Tensei: Persona 3

I have the MGS 4 80 gig bundle and it works fine. FES I don't know.

It should work fine on the 60 gig machine and all others with backwards compatability
but if you mean is there glitches, Then no I can't play Wipeout on the ps2 on my ps3 but Persona works fine...I am playing it on my ps3 now and have been for a week

I've played around the 2nd half of the game on the 60gig PS3 without any problems.

Not perfectly.

I had problems with the save files:
-Sometimes it told me the save process was unfinished because there wasn't a memory card inserted, but the second time I saved was successful.
-Sometimes I'd open the save menu to see that the file I was playing on was nonexistent (the other save files were still there) , but I'd just save on the empty slot and there was no info lost.

The game froze on the full moon on the 9/5 exactly like txcapricorn's problem
BUT I could solve it. Just don't do anything for about 2-4 minutes and the game will unfreeze itself.

Nevertheless, I could successfully finish the game with about 130 hours, so these little problems shouldn;t stop you from playing it.
