8x8 tiles and 8x32 reels, likely going to be very similar to skylncr.cpp or goldstar.cpp (which are both very similar anyway)
palette addresses are the same as unkch in goldstar.cpp, but the io stuff is definitely different here
board has an M5255 for sound
and an unpopulated position for a YM2413 or UM3567
