A while ago I spent some time poking around various drivers to find outputs. For the Drivin games I was obviously looking for the FFB data. I found some data in the hd68k_wr2_write routine that seemed to correspond to the FFB tests but couldn't make sense of it.
I started looking at the manuals and schematics and there's apparently a motor amp board. Does anyone know if there's logic on there that would need to be emulated or is just strictly amplifying the signal from the main board?
