Edit-- NONONONO nevermind.

 

You need to have PSP1000 or PSP2000 (non TA-088v3) that on cfw 5.50 GEN.Download 5.50 prometheus and extract to X:/PSP/GAME/[5.50 prometheus].
And if you have PSP3000 or PSP2000 (TA-088 v3 mobo) that on 5.03c,download the 5.03 prometheus.Extract to X:/PSP/GAME/[5.03 prometheus].Run the
5.03/5.50 prometheus update by going to you XMB --> Game (just the way you play a games).Follow whatever appear on your screen (3 clicks of 'X' button
if I remember correctly).After that you can check your new cfw on your XMB (SYSTEM SETTING --> SYSTEM INFORMATION).
Note : Directory X mention above is your PSP drive .

@ GreatCrippler
AFAIK retail games work on 5.50 prometheus. But I didn't try one (only tried clean ISO-Naruto-Ultimate Ninja Heroes 3 )

 

Been away from the PSP "scene" awhile, so I don't know Prometheus. Does this in any way work with the last M33?

 

I like running all of my games in .CSO format. For now, I think I will continue to patch my games and stay on M33. ^^

 

And what're you getting at? GEN and Prometheus firmwares play games in CSO format as well.

 

Wasn't there a mod for GEN firmwares as well?

EDIT: Yes there was, M33 fanboy. Here.

 

Welcome to the thread. >.<
This thread is about the Prometheus FIRMWARE that enables you to play games that you would normally have to patch with Prometheus (the program) without patching them first.

 

I sorry, I've fallen behind on PSP hacking. Last I knew prometheus was used to do the patching. OH BOY, another firmware for the PSP, just what we needed. I still haven't installed the GEN line of firmwares. I will stick with my 5.00 m33-6 and patch the ISO.

 

In the source page faq he has at the bottom, it says this:

Q: PSP-1000/2000's version?
A: I PSP2000 stolen, the thief to blame it all to blame.
(Google Translate)

Does this mean that it won't work on my Phat 1003 ?
I have 5.50 GEN D3 if it helps.

Also exactly how would I install this since there isn't any instructions ?
Bought it Pre-Modded so not done before.
