would like your opinions as i was going to hardmod my battery but if not needed i wount

theyre basically the same thing as a pandora battery (which is what you would have made by hardmodding your battery)
and you still need to create a magic memory stick and update to custom firmware to play downloaded games.

Well, there is that Test CFW function. You run CFW off the MMS when you do that. It's just a pain to go through the Pandora steps everytime though.

so might as well just hardmod a spare battery then cheers
