.
A single 64K 2-way set associative cache
Used for both instructions and data
Enabled only for addresses in the first megabyte
Works always in writeback mode
.
It is needed by the nforce motherboard bios that uses it to simulate a
block of ram at address d0000 before ddr ram is configured
* SPG2XX - Make audio emulation a subdevice
(I need to reuse some of it for SPG110)
* these will end up in different places on spg110 so split the handler (nw)
* refactor a little for cleaner use later (nw)
* realign logging with function names (nw)
* (nw)
* (nw)
* recent change in audio_beat_tick appears to break "icanpian jjs" seems unintentional? (MG please verify)
also documented an existing suspicious use of 'channel' in code.
* use channel_bit here instead, seems more logical (nw)
* reorganize code here a bit too (nw)
- 80 column card with SDX in CP/M mode.
- ROM/RAM banking fixed for CP/M, and MTX500 now correctly detected.
- Support for Type 03 and Type 07 .mfloppy images.
- Added alternate MTX2 romset (German).
- Keyboard ROM now selected in Configuration.
- Quickload .RUN files.
* Document cross-compilation options
* Use lowercase for some libraries that are lowercase in system32 on Windows anyway
* Make USE_BUNDLED_LIB_SDL2=0 not use the bundled SDL
New WORKING machines

Ms. Pac-Man 5-in-1 (Ms. Pac-Man, Pole Position, Galaga, Xevious, Mappy) (JAKKS Pacific TV Game, Game-Key Ready) [Sean Riddle, Peter Wilhelmsen, 19 external donators]
Disney Princess (JAKKS Pacific TV Game, Game-Key Ready) [Sean Riddle, 20 external donators]
New WORKING Software List entries

jakks_gamekey_nm:nrxdig New Rally X & Dig Dug [Sean Riddle, Peter Wilhelmsen, 19 external donators]
note, Pole Position is not really very playable at the moment due to raster rendering glitches, the rest are, aside from some obvious sound issues (nw)
New machines marked as NOT WORKING

Wheel of Fortune (JAKKS Pacific TV Game, Game-Key Ready) [Sean Riddle, 20 external donators]
There is a video rendering glitch (lkely another off by x lines raster issue) causing the letter selection text to not render properly, it appears the letters scroll instead of the text scroller below, which doesn't. (nw)
-spg2xx: Make rowscroll offset configurable, can't find register to control it, but JAKKS games need 0, while the chinese stuff needs 15 (nw)
-jak_wof: Marked as working, analog wheel isn't emulated, but is optional (I don't see where / how it maps) (nw)
-jak_wof: Improved inputs (nw)
-gamekeys now save to the gamekey seeprom not the system one (nw)
WIP checkpoint: while I believe it's largely accurate (and very slow), neither jazz nor sgi systems can fully boot yet using this device, so it remains experimental.
This implementation should go away when it has helped identify the improvements required for mips3.
- Added Slogger Plus 2 Expansion, Acorn Tube Interface and P.R.E.S. Advanced Plus 5 cartridge devices.
- Use derived 16Mhz clock on expansion bus and cartridge slots.
- Removed MCFG and added devcb3 in expansion and cartridge devices.
* Split up the different parts of ICO loading in the menus (locating files, scaling, drawing, etc.)
* Added icon support to software selection menu
* Added support for more ICO file variants, including PNG-in-ICO (new DIB parser is overkill for ICO but I can factor it out for BMP loading at some point)
* Added favourites filter for software menus - includes software that's favourited on any system, so GBC includes DMG favourties and vice versa
* Eliminated unnecessary member variables and O(n) walks in software selection menu
* Made the menus' cached texture structures a bit more efficient
