Is it possible for one to decompile psp eboots to obtain their source code?
If so can someone please help me in doing it?

It's possible to disassemble them.

You first need to download the needed tools: viewtopic.php?f=2&t=14717 (check the Tools link).

Then do the following:

Code: Select all

prxtool -o yourasmfile.asm -n psp.xml yourmodule.prx
Then build the following: https://github.com/uofw/uofw/tree/maste ... decompiler

Then you feed it with your disassembled file and it'll produce a nice decompilation.

Fully decompiling is not possible but, sometimes If you unpack iso file you can see "blahblah.lua" script like in GtaViceCity's or AngryBirds' iso file. If scripts are not encrypted you can directly edit these scripts with your notepad.

Oh ! I got him totally wrong. noname's method will give you physical memory addresses. You meant eboot.bin dumping ?

Hello.
Would it be possible for someone to edit PSP games for me?
I believe the source is required, and I don't know how to do it myself.
I will be happy to pay anyone who can do it if necessary.
Many thanks
