Use a GUI build for set-up. Bet you fix it.
I am not sure what you are saying to do here? Are you simply saying to use the GUI version of MAME?
I am running Hyperspin with mame.
Also tried mameui64 with no luck.....
If multiple mouse is enabled in the ini, then make sure it is remapped to the correct device. (mouse1, mouse2, etc)
I don't have this enabled. I thought I read in other threads it should not be in this situation.
But I also read about what you are saying (mapping to correct device)... where do you even do this?
