/****************************************************************************************

Super Wing - (c) 1985 Wing (UPL?)

driver by Tomasz Slanina

probably a sequel to flipjack
Hardware a bit (interrupts, sound) similar to mouser as well

TODO:
- unused rom 6.8s (located on the pcb near the gfx rom 7.8p, but contains
  data (similar to the one in roms 4.5p and 5.5r)

  The game currently crashes after the bonus round rather than moving on to
  the next level, it writes 01 to 0xa187 which is probably ROM bank, however
  banking the ROM in there results in the game crashing anyway, and looking
  at the data I wonder if it is corrupt, there are odd patterns in FF fill
  areas.

  (to access the bonus round take out the targets on the middle-left then hit
   the ball into one of the portals at the top left)


- dump color prom
- some unknown DSW and inputs
- hopper
- unknown writes
- measure clocks
