Guys look what i found in a site:
It's translated from japanese to english.5.03 Prometheus, 5.50 Prometheus latest UMD has been released and can start to guess at Narimashi what game patches, so I tested this feature 5.00M33 nowhere, I do not work if you are interested, simply made Since its introduction or procedure.
Although it has been confirmed to work until the problem of data compatibility and to introduce only tried saving it as a neta is not certain. Please try after understanding.
1. First unzip 5.03 Prometheus been downloaded.
[Primary?] PSP-3000 the country? Restraint solid results: CFW 5.03 Prometheus! (Yes? 另 跟帖? Removal) PSP? 合? District A9VG? Wan district's village?
2. 5.03 Prometheus prometheus_lite.prx extracted from the folder, flash0:/kd/ Copy.
3. Prometheus_key.txt same folder extracted from 5.03 Prometheus, flash1:/ copies.
4. Stargate.prx following folder Remove from 5.03 Prometheus, ms0:/seplugins/ Copy.
5. ms0:/seplugins/game.txt Open
That's it. If everything works UMD screen will flash red when you start the game, since the demand FW5.55 UMD games bare ISO / CSO directly or leave UMD Datsu should be able to boot from.
[Here and The God Eater KHBbS 』confirmed start at UMD.
So you can not start any games but please make sure sure that you understand.
We have added the module as a plug-in, so if you experience any problems from the Recovery Menu to disable stargate.prx just OK.
Anyway i had the same idea and i did it in my psp but i didn't know that the stargate.prx is a must have prx and it didn't worked.
Anyway now thanks this guy i know it....
