PSP a couple of psp questions

just wondering do psp games from bali work on our psp's?

if not does it work if you have a custom firmware?



Trust me, I'm The Doctor.
Bali is PAL, I think. You might have to have your PSP modded or a firmware crack added to be able to play games on it. I don't know where, or how, you can get that done but I'm sure you can Google it.
Custom Firmware voids your warranty, it is not recommended to put it on, if you do you can lead to the following:

Not abel to update to ofw (official firmware)
Things will stop working (i.e. UMD Drive stops spinning or wifi going wrong)
