To quote: Deci3dbg - Ida Pro debugger module for PlayStation 3

Whoever used to debug on PlayStation 3 knows that there is only one debugger available - SN Systems ProDG. It has some nice features (that I even miss in others debuggers) but overall... its not that good.

There also was a gdb client but it was pulled around 1.xx sdk (specification changed, there is no more step cmd, etc). So after some time that I spent with ProDG I realized that it just dont works for me and decided to get host debugger to communicate with Ida. It would have allowed me to use all those nice features like scripts, plugins, tracing, leaving comments in place, interface and hotkeys to which I am used to over the years.

Okay, I hear that someone of you is asking why I did Ida module and not some kind of gdb proxy instead, and...

Below are some related updates via Twitter (linked above):

Found the mistake in SPU Emu... -.- FAIL! sf* commands do rb-ra I did ra-rb -.- works perfectly now.

The sp somehow land in code section and overrides destroys code. so i don't update the code while the ls changes. This does the trick hotfix.

New spu emu soon dump function calls and channel access and so on.

SPU Emu v0.9: fixed sf* instructions and bugfixes and callstack functions. Dumps all branches now files get big ^^.

New spu emu soon dump function calls and channel access and so on.. btw no spu stuff just optimised code

Crypto function instructions implemented, aim_spu_module runs fine (v0.8).

Thanks to my tester we found a heavy bug which made the aim not run correctly. Fixing it.

I still got a problem with one instruction, the problem is idk what instruction, but aim decrypts the eid0 section fine with spu emu (v0.8.1).

To quote: SPU Emulation Alpha2 has been released: mBox implemented and MFC prepared, bugfixes, breakpoints implemented and all commands for metldr as far as KDSBest knows.

Hi Community,

I wanted to contribute to the scene, so I coded a tool that might help the community our members and fellow dev's. This Tool is intended for dev's so please be careful if you don't know what you do. I will not be held responsible for any harm.

My tool is a emulator for PS3 modules (e.g metldr), it is in pre alpha stage but I thought, it would be great to get some community feedback.

How to use:

Not all SPU Commands are implemented yet, but it is easily extendable and I will make it support DMA, all SPU Commands and SPU Mailbox soon.

First open a .kds file. Check out the metldr.kds to see an example....

First open a .kds file. Check out the metldr.kds to see an example. The rest is like a normal debugger. If you put dumps of your reversed functions in the KnownFunctions folder, it will detect it and mark that function for you.

Just for example Mark the whole cellSpuAesDecryptCbcCfb128 function in HexView in IDA -> Right Click -> Save...
