So what is at d0000000 ?

0c000000 is the flipper-compatible stuff
0d000000 is the hollywood new devices
0d800000 is the same as part of 0d000000, but with some extra bits
sometimes.

Also, when in Wii native mode, stuff like EXI, SI and AI (which is flipper-compatible stuff too) is available at 0d000000 only.

You might want to pick a more descriptive name for this,
"serial" is usually understaood to mean "RS232".  Which
this isn't.

What is it then ? You definitely want some other name if it's not
classic rs232 style serial.

It's SPI I think, with some extra signals.  It's the gamepads mostly.

EXI is SPI.
But SI is a different thingy.
