Decompiling a prx

hi everyone

i was just wondering how can i decompile a prx file to c/c++ ?

if anyone knows please tell

Any one Plzzz

I believe it is possible but you need sufficent programming knowledge

Well i Knew That :D

But How Can i Do it I Want To Dissasemble It To The C++ Files

Doesn´t exist a convenient way to convert Assembly code (in that case MIPS instructions) to higher level language like C++. In the PSP case is worse because it follows the RISC arquiteture... it´s mean a large set of simple instructions for every line of C++ code.. consider the optimization provided by the compiler and you will get a bunch of assembly code without some meaning for humans ( at least it is very,very hard to understand).
Reverse enginering it´s not to easy ... you must analise the code running and try undertand what it does.

If exists a easy way to decompile programs ,why people dont found the source code of a lot of comercial programs like Windows, MS Office, Photoshop, etc ?
