please help me! i downloaded cheats to my psp. I went to saved game files and i saw edison carters cheat device. When i loaded it it said it was corrupted! What do i do!!!????!?!!?!?!??!?!?!?!??!?!!?!?!

what firmware are you on

if you dont have a homebrew enabled psp, make it homebrew enabled
if you have a homebrew enabled psp, make sure the savedgame is the correct region, and if it is then get the prx

must likely you have a newer fw, and therefore the exploit is patched, you have to get the prx from
cheatdevice.com
