i just bought a 2nd hand psp 2000 and it came with a PRO nightly cfw. Can someone explain to me what that is? I'm not that familiar with PRO. My psp fat was on M33-6 and can comfortably switch to Gen with ease and i understand well how that goes but im really new to this PRO firmware and i don't want getting my new slim end up as a paper weight. oh, and yeah its on TA-088v3 mobo too.
