/* 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 */ /* TWO MINUTE DRILL - Taito 1993?
