To anyone who plays "homebrew" games or copies of games they own from their memory sticks:

I just downgraded to firmware 1.50. Do I need to install a certain custom firmware for the ISO's to work or can I download any firmware and all ISO's will work?

 

use dark alex's m33 firmware. i think i went from 1.5 to 2.7ish to 3.5 to 3.9

pm me if u need help and ill give u the sites for the firmware and tutorials
