3.71 M33 required?

I just used the pandora battery fix to load the 3.60 custom firmware on my new slim. so.. do i need to upgrade to 3.71 custom, or can i still play ISOs using my current config?

Also, could someone point me in the direction of a good tutorial on getting the PSP ISOs to run? All I see are a bunch of "how to use/make the pandora battery" threads. Thanks!

The reason you don't see any ISO chatter is because it's banned per board rules.

As I understand it, there isn't much difference on the Slims between 3.60 and 3.71, but the main thing you need to watch out for are official games requiring a certain firmware.

3.60 dont have themes
3.71 have themes
