problems with ADHOC

I've upgraded my psp from 3.03 oe-A straight to 3.03 oe-C. I used multiplayer on the Genisis and SNES emulators then the next day it all of a sudden didn't work. When I try using a proper game I get an error code 80410B05.... Is it the firmware thats buggered it. Do I just upgrade to 3.10 oe or do I take it back to Sony? I'm affraid they'll say they can't fix it because I've messed around with the firmware.

why dont you just reinstall the firmware to check if thats it or not....

if its not the firmware, reinstall the Dgen emulator (im assuming you are using the best genisis emulator out there)

^oh same thing with the SNES except it should be whatever your snes emu is
