i would realy want to look at warzone code cause the game is so bad, you can think of 10 problems and 0 good things... servers cheap, developers probably cheap as well cause such bad game, crashing, lagging, lagging whole PC in alt tab, constant bugs as example when already landed get teleported up as if landing again in plunder... its so bad... always 99% GPU and low fps while game looks like 2005 game on all low

As a heads-up, you can rename and retype variables within Ghidra, and it'll produce more correct/nicer output. You can also create data structures within Ghidra, and get even nicer output.

@Exellys I’m familiar with opening a binary in a reverse engineering program like Ghidra, but how do you get .asm files from the binary that I can put in a folder and maybe share so others can collaborate on decompiling a game?

In Ghidra is possible dump and rip 2d sprites and 3d models from any games consoles to pcs ???
@darthvaderbn6 ай бұрын
No, for 2d game, you (mostly) have to use an emulator with debug tools. But with 3d assets it's complicated, older games (from 5th generation to 7th) use different extensions for models (for example: super mario sunshine models are easier to dump than mario party 4-7 models)

Heb advies voor je, leer eerst C/C++ goed genoeg snap hoe pointers werken en daarna leer assembly x86 (eigen ISA) daarna vind tutorials op hoe statische analyse met IDA/ghidra werkt en probeer een paar crackme’s te doen. RE leren is veel praktische ervaring op doen en veel proberen. Goed advies is ook godbolt/dogbolt gebruiken voor interactieve deassembly en eigen C/C++ apps maken en dan de asm lezen en snappen hoe de structuur in elkaar zit.

Is it possible to decompile or to reverse engineer, say a PS4 games .exe to get an approximation of how an actual source code look like and build a port from there? Say run PS4 exclusives on jailbroken consoles like PS3 or Xbox 360 wiith cut-back here and there for final version. Ignore the performance, can we make it run at all at say 10 fps for first iteration (v1.0)?

"PS4 games .exe" are you ok?
@isaiahkern94347 ай бұрын
none of the comments here are that informative. For clarity sake, the OP is unaware that .exe is specific to windows, but I believe the intent was to refer to the program/game's code being ran. I'll just refer to it as execution format) As for OP's question. Which I'm taking as "could a ps4 game run on a xbox 360 or ps3, if it was reversed engineered converted to source code. then compiled for 360/ps3" On paper, sure, maybe. In practice it's way more complicated, and could be a no. For example, someone is working on a port of legend of zelda OOT to a ds. The ds on paper is technically "weaker" than a n64 if we're just talking raw clock speeds. But due to what in the hardware, and specifications, certain tasks can be done faster than then n64. But that's the problem, you need someone who not only knows enough to reverse engineer a ps4 game, but someone who also knows the in's an outs of the target console. And there are likely some tasks that just, cannot be done on a weaker system (at a reasonable framerate)

@isaiahkern94347 ай бұрын
@@soraaoixxthebluesky of course, no problem. If anything, you may want to look up and into what assembly is and how it works. And the relationship between a executable format (start with a windows .exe) assembly programing, and operating systems (like windows) is it will take a quite a bit of time, but it will help prevent scenarios of getting effectively laughed at. Which is pretty rude.

@bobbyaremyshoes2233 Жыл бұрын
Thanks, nice info. I didn't know that you actually don't need to understand code fully while decompiling. But there is one problem with this code-comparing approach. For example, the original devs could have different (much older) version of the compiler or even write the assembly by hand (from my experience handwritten code may drastically differ from the original). In that case by simply compiling with a modern compiler you won't be able to get the same output, especially down to the hash matching
