View Full Version : New Custom Firmware - 5.50 Prometheus - is released!

5.50 Prometheus, newest CFW created by Liquidzigong (of earlier Prometheus ISO patch fame) released today, supposedly allows for playing all recently released 6.20 games, including titles like Metal Gear Solid: Peace Walker or Kingdom Hearts: Birth By Sleep without patching. Download link below.



I've only just installed it myself and it's more of a patch for 5.50 GEN D-3 than a full blown CFW.
It flashes 5 prxes, all into flash0:/kd/ folder, and those files are moon.prx, peagasus.prx, prometheus_lite.prx and vshctrl.prx. Everything seems to work fine, sadly I don't have any 6.20 UMD's I could use to try out it's main feature.

***2nd update***

I installed 5.50 Prometheus last night and now all my save files are corrupt. Is there any way to save them?

Sadly yeah but you know all i want from the CFW is to play two of the games i have bought/ripped that i only really play (GT and FF:CC) and my PSone purchases that require the emulator from 6.20.

Im not even that worried about store access now since i can just buy via PS3 and transfer it to my PSP.
