@ -21,8 +21,6 @@ TODO:
- add internal artwork
- it does a cold boot at every reset, so nvram won't work properly unless MAME
adds some kind of auxillary autosave state feature at power-off
- serial comms doesn't work, 25MHz XTAL is correct and the SCI baud rate is
configured as close as it can get to 57600, but it still desyncs quickly
