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.
