Notes:
- Unless there is some special logic related to NMI enable, the game doesn't
  rely on vblank for timing. It all seems to be controlled by the CPU clock.
  The NMI handler just handles the "Stop Mode" dip switch.

TS 2008.06.14:
- Addedd sound emulation - atomboy and fghtbskt req different interrupt (T1)
  timing than wilytowr, otherwise music/fx tempo is too fast.
  Music tempo and pitch verified on real pcb.
- Extra space in atomboy 2764 eproms is filled with garbage z80 code
  (taken from one of code roms, but from different offset)
- Fghtbskt has one AY, but every frame writes 0 to 2nd AY regs - probably
  leftover from Wily Tower sound driver/code
- I'm not sure about sound_status write - maybe it's something else or
  different data (p1?) is used as status

TODO:
- Sprite positioning is wacky. The electric 'bands' that go along the pipes
  are drawn 2 pixels off in x/y directions. If you fix that, then the player
  sprite doesn't slide in the middle of the pipes when climbing...
- Clocks

Dip locations verified for:
- atomboy (manual)
