Checklist

I have searched for a similar issue in this repository and did not find one.

Description

I see two way to debug loaded ps4 code

using IDA Pro (or maybe NSA Ghidra, but not sure), and gdbstub in shadPS4
using VS2022, and set int3 as breakpoint in POI - as eboot.bin always load at same address, the POI addresses can be found in ida dissasembly. But there is a problem - how to return original code, replaced by int3?

what do you think?

Reason

some games just not working because of problems deep inside the code, and no way to found problem just looking at log

Examples

https://github.com/shadps4-emu/shadPS4/pull/2339
sceVideoOutDeleteFlipEvent called AFTER error in game, and it releases resources. Real error somewhere early

I’ve been working on a GDB stub, and so far I’ve gotten IDA to connect to it and read memory. However, there are still some issues; I’ll make a PR soon™ hopefully.

If you want to help Devs, you can come on Discord and ask for help how to setup everything.
They already use Ghidra and others tools to do RE and more.
There is also devtools available for the emulator, they can explain to you how to use it on Discord too
I'm closing this one
