Details / Status

Rewrite the vp906iii driver:

  • Done.
    • Rearranged GFX in two different banks.
    • Decoded GFX properly.
    • Rewrote the memory map based on program ROMs analysis.
    • Hooked two SY6520/6280 (M6821) PIAs for I/O.
    • Hooked the SY6545 (6845) CRT controller.
    • Fixed size for screen total and visible area based on SY6545 CRTC registers.
    • Added all inputs through PIAs.
    • Added proper sound through AY8910 (mapped at $0840-$0841).
    • Fixed AY8910 volume to avoid clips.
    • Proper colors through color PROM decode.
    • Demuxed inputs (thanks to Dox that pointed me in the right direction)
    • Added some game-protection workaround.
    • Added NVRAM support.
    • Renamed driver, set and description to match the real game.
    • Added technical notes.


Emulate protection in Magic Fly:

  • Done.
    • Added proper emulation to the game protection that allow boot the game without patchs/hacks.


Emulate protection in 7 e Mezzo:

  • Done.
    • Added proper emulation to the game protection that allow boot the game without patchs/hacks.


Hook the inputs properly in pmpoker.c games:

  • Done.
    • Removed all inputs hacks.
    • Connected both PIAs properly.
    • Demuxed all inputs for each game.
    • Documented all outputs.
    • Added lamps support.
    • Created different layout files to cover each game.
    • Add NVRAM support to all games.
    • Corrected the color PROM status for each set.
    • Figured out most of the DIP switches.
    • Added diplocations to goldnpkb.
    • Replaced the remaining IPT_SERVICE with IPT_BUTTON for regular buttons.
    • Updated technical notes.
    • Cleaned up the driver. Now is better organized and documented.


Rewrite the ltcasino driver:

Analyze the ltcasino & ltcasin2 program ROMs to fix all wrong aspects of emulation.


Demux and rework inputs in Magic Fly and 7 e Mezzo

  • Done.
    • Figured out how the protection works.
    • Removed the hacks/patchs that formerly allow boot the games.
    • Figured out how the buffered inputs works.
    • Demuxed all inputs for both games.
    • Unified the memory maps from both games.
    • Added NVRAM support to both games.
    • Crystal documented via #define.
    • CPU clock derived from #defined crystal value.
    • Changed CPU clock to 833 kHz.
    • Mapped DIP switches.
    • Found the maximum bet DIP switch in magicfly.
    • Removed flag GAME_NOT_WORKING for both games.
    • Managed the planes to get the 3bpp GFX colors accurate.
    • Renamed the ROMs acording to pcb pictures and ROM contents.
    • Cleaned up and optimized the driver.
    • Reworked/updated technical notes.
