@RikuKH3 OK it looks like I dealed once and for all with ISO.BIN.EDAT.
I decrypted the file, linked it to search for an other activation file (Xi's demo) but remain all the important calls that Cobra have in that file. It's a PSP EDAT, the encryption is already defeated on those files.
Grab the file and replace it with the previous ISO.BIN.EDAT on PSP Launcher Folder:

It now launches normally.
I'm gonna have to test again all the possibilities... XD

All files patched, I'm not sure if it is important, but this way we can test all possible combinations for which files are needed and not needed to get patched.
I need somebody with the dongle to try it.
I'll send him all the possible options/combinations for it to work (they are 4 or 5 don't worry).

Do you understand what you're talking about? How in the hell you can hex compare encrypted data?

No you don't, stop lying. This is ridiculous. I saw what you did and this is pathetic.
There's no way you succeed in what you're doing, but maybe you learn something in process. That's a good thing. Have a nice day.

So the iso.edat.bin is NOT decrypted?
nothing like being rickrolled... again... and again...

The byte length will always be identical.

I'm not gonna comment in this offensive post, because it's ridiculus and pathetic, but maybe you learn something in process. That's a good thing. Have a nice day.
NEXT!

Have you managed to get anywhere with this as of yet?

Yes, it works, emulator stays idle, I need a backup manager that will do the same work as Cobra's Manager to mount games.
This is where my work ends... :/

Any plans to see if you can figure out how to get the Game Manager to load on 3.55 without the dongle?

Also do you have a pkg you have made with your working (yet hanging) version?

It won't work in any way, you need to patch alot of stuff in a specific firmware to do that and most of that, I'm not aware or I have the knowledge at all what they are.

I provided a link with all of the files.
Just install the launcher and replace the files, it's not worth making a pkg for now, waste of time... :/

ic, I had downloaded your file and copied it over but I still get the Need activation screen
