Any one revering the SPI service? I've been looking into it some, as I would kinda like to have some custom SPI stuff.

Any more info?

To be more specific is there a way to get access to the game card SPI without the save system in the way? IE raw buffers for the SPI.

Done some RE of the SPI, I know what each function does, but I don't know which devices are controlled through that service. Probably the microphone, wifi firmware, and the NVRAM (DS profile settings), most likely.

Game card SPI = pxi:dev SPIMultiWriteRead (see TWLSaveTool's source code) with "Use card SPI" arm9 flag.
