Disgaea 3: Absence of Justice [BLUS30181]

I did that with (NisGraphics.spu.self) and recieved NisGraphics.spu.elf in same folder, what's next ? Cause just run the game and still got that error ?

* openModules: ERROR! exit. (ret=0x88000002, file=NisLib/NisMovie.cpp:453)
* _NisMovie_Open: ERROR! exit. (ret=0x88000002, file=NisLib/NisMovie.cpp:794)

Rename the file you recieved, NisGraphics.spu.elf, back to NisGraphics.spu.self (and therefore replace the old one, make a backup first, I didn't do this, and can't easily be bothered to get the file again off the disc to test myself) and run the game. That error is unrelated, and will persist.

Did that, but no success. Still got that error.

I guess it would be better if you upload your working NisGraphics.spu.self.
