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 ^^.

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.
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.
Just get back to me at twitter
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.
It is not for game emulation and it will never emulate the ppc. If you want that go to code.google.com/p/rpcs3/ , their work is not done and nearly nothing work, but they are the guys that write an emu for games and so on. This is just for reversing, so you don't have only a static analysis.
