[quote name='uberzone']I'm running the 2.71 custom firmware and it works great. It allows you to run any homebrew application that needs 1.50 firmware. In addition is also lets you run UMD games that require up to 2.80 firmware.
And whoever said emulators don't run well on the PSP doesn't know what they're talking about. I'm currently running a NES, SNES, Genesis, GBA emulator as well as Doom and Quake which work awesome for the most part. Some games. mostly for the SNES and GBA emulators run slow but considering you're playing them on a portable system is understandable.[/quote]
QFT. I'm using DevHook .46 (I haven't tried the and I can play anything up to 2.71FW whether it's an ISO or a store-bought game. In addition, I can play my NES and GB/GBC emulators perfectly with zero framerate issues. The SNES and GBA emulators are playable but not 100% - some games work better than others.
