i liked what i had so far, but it was a bit more work to play an .iso than i wanted, to i followed the tutorials on here to downgrade my 2.71 ta-082 to a 1.5, then i upgraded to 3.02 oe-a, then to b. the firmware is great, the only thing is is that my memory card seems a little cluttered. can i format my memory stick now or do i have to leave all of it on there? also in my game saves now i have two icons that simply say "corrupted data". WTF?
