Custom Firmware 5.50 Prometheus for PSP-2000 and PSP-1000

Not forgetting PSP-1000 and PSP-2000 owners, Liquidzigong has released Custom Firmware 5.50 Prometheus for PSP-2000′s (TA88v2 or less) and all PSP-1000′s. So putting an end to all that patching to get 6.20 Firmware games to work. Its very easy to install. From Custom Firmware 5.50 GEN-D3, just extract the CFW 5.50 Prometheus folder from the winrar archive over to your PSP memory card PSP/GAME/ and run the installer. -"On the release site it says that it was made using mostly Gen. it says to “think of it as Gen-D4.” It's very similar." -"Works for the last PSP game released, Naruto Shippuden Ultimate Ninja Heroes 3." -"After installing prometheus, you don’t need to use the switcher anymore." "All your saves should work."

Naruto? Everybody's complaining about Metal Gear PW. Anybody tried this firmware? I think if kLown supports this firmware, why not?
