Driver by David Haywood
TODO:
- macrossp: tilemap zoom is wrong, see title screen (misplaced) and level 2 boss
(background scrolls faster than sprites)
- should use VIDEO_RGB_DIRECT for alpha blending to work, but tilemap_draw_roz()
doesn't support it.
- Sprite Zoom on quizmoon title screen isn't right
- Tilemap zoom effect on macrossp title screen and probably other places
- Priorities (Sprites & Backgrounds) - see quizmoon attract mode
- sprite/tilemap priorities might not be 100% correct
- Sound
- optimize palette fading in macrossp.quizmoon doesn't use that register.
- All Other Unused Reads / Writes
- Correct unknown ports if/as needed
- Clean Up
- Flip Screen support (both games have a dipswitch for it's selection)
Notes:
Whats the BIOS rom? should it be in the 68020 map, its different between games.
- what is the 'bios' rom for? it appears to be data tables and is very different between games but we don't map it anywhere
- priorities
- zooming is wrong
- is alpha REALLY alpha or sprite flicker?
- convert tilemaps to devices?
68020 interrupts
lev 1 : 0x64 : 0000 084c - unknown..
