how would you know if the psp version you've just bought is not just downgraded version?

Question

is there anything i can check if the psp i bought was not higher version downgraded to make it 1.5? is there a way i could check on the unit? TIA!!!

i do care coz im afraid that downgrading might cause problems on the performance of my psp in the future. but thanks for yur time in answering!

Answer 1

who cares, 1.5 is what you want anyway, it's the best for running homebrew, go here www.psp-hacks.com for more info and how to run 2 versions of firmware (1.5 and 2.71 for example)

Answer 2

Every PSP that comes in the value package is Firmware 1.50
