TODO:
- finish 8275 CRT emulation
- fix gfx glitches
- finish 8275 CRT emulation, split off as device
- fix gfx glitches and banking
- correct colors
- DIPs
- layout(lamps)
- NVRAM
Notes: at least on dwarf's den hardware, the current card set/dwarf set can be swapped
by pushing the buttons in this order: 1-4-1-4-2-1-3-5 ('zvzvxzcb' in mame)
Doing this with the default dipswitches results in an error; The code needs to be investigated.
Setting all dipswitches active and dipswitch 10 inactive allows game/gfx switching to work, but gfx
are all corrupt/scrambled.
Also the dipswitches are active low/inverted, since on the machine this was tested on dipswitches 2,3,5,6,8 were ON, and 1,4 and 7 were OFF.
There are only 8 dipswitches populated on the Dwarf's den boards seen so far.
DD hardware is weird and complicated. There's no dedicated DMA controller
for CRT. When serial output pin of cpu is in high state, all reads from
