tvgames/xavix*: Lots of XaviX, XaviX2, and SuperXaviX updates [David Haywood]
* superxavix: some research on the bitmap layer, slight visual improvement where it gets used * xavix - begin to move towards a cleaner bus implementation without the memory bypass (as some later SuperXaviX games will need it) * superxavix CRTC(?) logging * make bitmap writes kinda work in suprtvpchk demo mode * attempt to improve plotter behavior * some experiments for tak_chq * some extra logging for math unit * start moving some superxavix specifics to their own class * a few xavix2000 opcodes * note about loading screens on some super tv-pc sets * possible workaround for the super tv-pc issues, there's definitely something more funky with the superxavix address buses * added missing cmc_imp opcode for ban_ordj (sprites now appear in demo) * swap tilemap priorities in cases where priority is equal (for epo_golf) * document how noise effect is enabled, even if it isn't currently understood * some notes of things that need revisiting * implement tile addressing mode used by epo_stad * more closely match math unit behavior to some hardware tests * use more appropriate external bus sizes in some cases * added 2 more sets, one SuperXaviX, one XaviX2 * start trying to understand the extended mode anpanmdx uses * xavmusic research * some of the anpanman inputs are simple button responses at least * improve epo_doka sprites * assume bitmap layer has lower priority than tilemaps (several cases suggest as much) * mark supertvpc 'double mouse' cart as a bad dump because the code looks corrupt in places, add 2 workaround to boot other sets so that graphic features can be better tested * add some (not correct) mouse handling to supertvpc * update some notes * start trying to improve superxavix IO * add Piano PC New NOT WORKING machines ------------------------------ Anpanman Kazoku De Ikunou Mat DX (Japan) [TeamEurope, David Haywood] Let's TV Play Dragon Ball Z Battle Experience Kamehameha 2 Ossu Ome Goku Tenkaichi Budokai (Japan) [TeamEurope, David Haywood] Doraemon Moving!
