I just got mister ao486 (win 3.11 and dos 6.22) working thanks to some images from nml. Sound works also (my own vhd based on smokemonster win 95 would not output sound).
How to get a usb controller to work?
I went to ao486 input settings, and used my buffalo snes usb controller to set the keys. Didn't work.
Btw...keyboard works splendidly! I googled a little bit, and couldn't find anything about usb controllers.
