Hi

I'm new into the psp scene so im still deciding what to do with my psp go.

It is currently running 5.70.

The doubt here is what to upgrade to?, from what ive seen theres a 6.20 TN PERM and not PERM and the 6.35 PRO (going on B3) that isnt a PERM solution. Don't know if theres any other options.

Other question is that if, like on PS3, new games require 6.37+ firmware to run, and if those games are modified in any way to run on older firmware versions?

Thx and sorry for all the noob questions.
