Gaming Latest firmware?

[Blaze163]

I'm currently running a PSP 1K on Prometheus 2, and it can play all my UMD games except one. Ace Combat X2 Joint Assault. Won't run it at all. Until now I've been borrowing my dad's PSP which will play any UMD as it's on official firmware, but now he wants it back. Is there a firmware I can use to play ACX2 without having to swap between various settings every time I play, and without losing the ability to play the armada of 'borrowed' games on my memory sticks? I've not checked the PSP scene in a while so any help would be appreciated.

I don't know you could try 5.50 Prometheus-3 the latest 5.50 Prome-3 release would be V4. UMDs should work on Prometheus CFW though so give it a shot once again with the latest update
