Ok, I got a big ol problem. For some reason, my PS2 can't SEE PS1 memory cards! O.O Its modded with a Magic 3.1. It doesn't boot sometimes, but I figure thats cause I'm using the standard W point and not the mod point.
Anyways, not being able to see the PS1 memory cards is a big no no. It can see the PS2 ones fine though. Just noticed it today while trying to play DDR 5th mix.
