Prometheus Released: Play More 6.20 Required Games on Custom Firmware
greg | May 19, 2010

And the hacks don’t stop… Introducing liquidzigong’s Prometheus — craftsmen will worship this — play [more] 6.20 required games on custom firmware 5.00 M33 or 5.50 GEN. Once again it’s a process but you know that’ll be simplified sooner or later… Probably by Hercules or someone.

What you’ll need (download below):

Prometheus
WQSG_UMD
UMD Dump PRX
PRXDecrypter or ISO Tool

What to do:

Create an ISO of whatever 6.20-required game.
Open that ISO in WQSG_UMD and browse to PSP_GAME/SYSDIR.
Extract EBOOT.BIN to a temporary folder.
Use PRXDecrypter (or ISO Tool) to decrypt the extracted EBOOT.BIN file and rename it to EBOOT.OLD.
Extract the Prometheus RAR archive so you have prometheus.prx and a new EBOOT.BIN.
In WQSG_UMD drag ‘n drop the EBOOT.OLD, EBOOT.BIN and prometheus.prx files back to PSP_GAME/SYSDIR. See above screenshot.
Copy the ISO to your memory stick and try it out.
Using UMD Dump PRX and ISO Tool you could probably skip a step or two. You know, there’s more than one way to skin a cat.

Also mentioned at the source is that KHBBS works using the above + this extra bit: (I haven’t confirmed it myself)

for KHBBS, you have to decrypt BBS1/2/3.DAT then put back to PSPGAME/USRDIR
for 5.00M33, you have to decrypt all PRX files (EBOOT.BIN，PSPGAME/USRDIR/MODULES/*.PRX) then repack the ISO
orevious modification on EBOOT.BIN/PRX files (like sceUtilitO”) are not required
