i downloaded a game but i dont know how to play on the PSP. and yeah, am a n00b on that cuz i just bought my psp today. i hope this aint against the rules and thank you in advance for your help.
You need to downgrade your PSP to 1.5 then upgrade to from 3.01oeA to 3.30oeC. Thats custom firmware. When looking for a downgrader BE CAREFULL! theres a lot of fake stuff that can destroy your PSP. Oh and after you have the custom firmware, you need to convert your ISO into an eBoot format and then stick that into the psp/games folder.
