So being the chump I am to PSP modding, I blindly followed a guide and managed to get 5.50 MHU installed. But just taking a look at the threads here, I see that most people are using GEN-x type firmware... So from what I understand, the GEN stuff is still being updated and would be better for running new games? Since I'm only interested in mostly the old stuff, I should still be good no matter which I choose? Also: if I wanted to switch to GEN, do I have to flash my psp again with the pandora battery/mms back to 5.00-m33 and update from there?
