need help, i have no idea whats going on.
i just read into this rom thing for psp like a day ago, this whole downgrading, firmware, motherboard, etc is confusing. i was just wondering like what are the advantages to downgrading your psp to version 1.5? and does it mess up the way you play your umds? right now i have a version 2.71 but i dont know how to check for the motherboard thingy. all i know is that i got this second hand and it was purchased in US. so can someone plz tell me how to downgrade if it is even worth it ? thanks
