I was adding some floppy stuff to the softlist and I think I have found a regression in the MPU-401 MIDI device, it just doesn't work anymore. At first I thought it could be related to
this commit because the address map probably should be "map(0x0, 0x3)" instead of "map(0x0, 0x0)", and changing that makes software recognize the card... but it still doesn't output MIDI data, so there has to be something else.
0.196 was the last version where it worked, so it definitely happened between that and 0.197.
