Two Minute Drill - Taito 1993
-----------------------------
Half Video, Half Mechanical?
(video hw + motion/acceleration sensor ?)
preliminary driver by
David Haywood
Tomasz Slanina
TODO:
- simulate the sensors (and remove rom hack)
- controls/dips
- 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
