i currently have 5.00 m33-4 (but i cant play a few games, specifically the minis)
so should i go ahead and install 5.50gen-d?
and how cuz i never installed a firmware before
please help :)
oh and i have a psp phat.
and also alot of 1.50 kernal homebrew installed, will the firmware update mess that up?
