If you play lots of ISOs on your PSP, then a custom firmware that includes the Inferno Driver is a must. It has the highest compatibility for even the most poorly created backups. Thanks to some swift modding by Rahim-US, that feature that used to be exclusive to PRO firmwares is finally making its ME debut! Included in this download are updated ME and LME custom firmwares for 6.20, 6.39, and 6.60. LME is to be used on PSP-3000 and GO, while PSP-1000 and PSP-2000 have the benefit of regular ME. 6.20 is generally recommended for newer systems because the firmware can be permanent patched much like the 1000s and 2000s. That patch is also included. Check out the full changelog below!
