- Emulation by Bryan McPhail, mish@tendril.co.uk
- Improvements by Pierpaolo Prazzoli, David Haywood, Angelo Salese
-
- todo:
- both games
- - correct ROZ rotation (single register that controls both);
- - flip screen support;
- - according to a side-by-side test, sound should be "darker" by some octaves,
- likely that a sound filter is needed;
- cntsteer specific:
- - In Back Rotate Test, rotation is tested with the following arrangement (upper bits of rotation parameter):
- 04 -> 05 -> 02 -> 03 -> 00 -> 01 -> 06 -> 07 -> 04 and backwards
- Anything with bit 0 set is tested from 0xff to 0, with bit 0 clear that's 0 -> 0xff, fun.
- - Understand how irq communication works between CPUs. Buffer $415-6 seems involved in the protocol.
- We currently have slave CPU irq hooked up to vblank, might or might not be correct.
- - invert order between maincpu and subcpu, subcpu is clearly the master CPU here.
- - understand why background mirroring causes wrong gfxs on title screen_device.
- Probably area 0x2000-0x2fff enables tile bank bit 8 and write addresses have same mapping as reading.
- A preliminary decoding is in tilelayout_swap;
- - tilemap flashing when gameplay timer is running out;
- - tilemap scrolling, correct only for title screen.
- Maybe upper scroll bits also controls startdx/dy?
- cleanup
- - split into driver/video;
