 Two Minute Drill - Taito 1993
 -----------------------------
 Half Video, Half Mechanical?
(video hw + motion/acceleration sensor ?)

 preliminary driver by
  David Haywood
  Tomasz Slanina

TODO:
 - understand the ball hit sensor
 - simulate the sensors (there are still some shutter errors/defender errors that pops up)
 - Hook-up timers for shutter/defender sensors (check service mode)
 - Dip-Switches
 - find video control regs (layer enable, scroll)

BG scroll:
BG maps are 2048x256 (128x16 16x16 tiles).
There's some kind of double buffering - odd/even screens are at
x offsets 0 and 512 (it's visible during distance count after throw (odd/even numbers))

looks like regs @460000 are used,  pairs at N, and N+8, so
460000, 460008
460002, 46000a
460004, 46000c
460006, 46000e
