didn't think i'd be needing help this soon, but here goes (btw, if i've posted this in the wrong forum, sorry. seemed to be the most appropriate place to ask) i got my hands on an r4 a little while ago (friend gave it to me and I wasn't gonna say no) and things were all good for a while, though I noticed whenever there were voice overs in Megaman ZX Advent, the video would lag significantly and Final Fantasy IV liked to freeze on me. I just figured I'd buy those games and move on. Then i tried out final fantasy tactics a2...no problems until i try to enter the auction house for the first time. Screen fades to black....and stays black. I only bring it up because i don't think i've ever come across anyone else with the issues i've got on my hands. the r4 is currently up to date with the 1.18 kernel and i'm using a sandisk 2gb microsd. so, are there any fixes i can try? or do I owe my friend a punch in the eye for pawning off a dysfunctional r4 (and making me replay a couple hours...gotta remember to save more often) thanks. and again, if I've posted in the wrong forum, my apologies.
