@ -10,8 +10,9 @@ NOTE: nsnova does an NMI at power-off (or power-failure). If this isn't done,
NVRAM won't work properly (supremo doesn't have NVRAM).
TODO:
- if/when MAME supports an exit callback, hook up power-off NMI to that
- beeps are glitchy, as if interrupted for too long
- if/when MAME supports an exit callback, hook up power-off NMI to that
- nsnova MCU internal NVRAM belongs in m6801.cpp
- nsnova serial port isn't working, MCU emulation problem?
- nsnova unmapped reads from 0x33/0x34
- is "Aquamarine / Super Nova" the same rom as nsnova and just a redesign?
