Below are some related Tweets on the update via Twitter (linked above), as follows:

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).

TeaM_AC1D in the wild, from one of our newest and highly skilled members KDSBest we have something nice for the scene - a PS3 SPU emulation pre-alpha module that allows x86 PCs to emulate the SPU.

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. 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 to File. Name the File "cellSpuAesDecryptCbcCfb128" without extension and copy it to the KnownFunctions Directory of the Emulator. Now all similar functions get automatic detected!

"Step" Executes next command, "Run" runs till breakpoint (Breakpoints are not implemented yet). Debug SPU Code in Windows.

Any questions? Just get back to me at twitter

Stay tuned

PS: Thx for MK and cfwprophet (Team Acid) and of course to fail0verflow for anergistic, which helps a lot with it and even uses some functions of them.
