PSX executables refers to the Executable and Linkable Format files utilized by some disc-based console systems (including PSX, Dreamcast & Wii).

You don't "run [a] game in" a decompiler. A decompiler simple converts compiled executables back into human readable code.
I used to be a ROM hacker like you. Then I took an arrow to the feels.

This is a very good and informative thread! The PSX could always use more documentation!

M i missing something ?

Thanks a LOT in advance!!!

This is the routine that i want to get in, in order to get to another. I would like to be at least, able to put a breakpoint in it, but i am not figuring out how i can do it.
000288fc: addiu r29,r29,0xffe0
00028900: sw r16,0x0010(r29)
00028904: addu r16,r4,r0
00028908: sw r17,0x0014(r29)
0002890c: addu r17,r5,r0
00028910: lui r4,0x8001
00028914: addiu r4,r4,0x0990
00028918: sw r31,0x0018(r29)
0002891c: jal 0x 000286b8
It is possible to in some way, to put breakpoint on this peace of code?
Thanks a LOT to you guys.

So how about the GPU window of the debugger? Is there any way to find how to rip 3D models or even textures, from the game?

Ok I was trying to figure out how I can brakpoint a gameshark code inorder to find out the assembly instructions actually writing to the players health say for instance in order to find the exact bytes I can search in a hex editor to alter the rom directly I have done it with snes games already but psx games are acting weird and I dont understand

does the gameshark code write to the RAM address that stores the health, or does it modify the code that alters the health? I mean, you could always set a write breakpoint on where the health is located and where it breaks say, when you take damage, it should break on the routine that handles that.
as for your games acting weird, no idea, it's possible you may be editing the wrong spot, I'd have to see exactly what you're trying to do, but honestly, there are better communities out there that could help you better than I could. Hell, I barely come here anymore.
