Details / Status

Rewrite the vp906iii driver:

  • Almost done (in progress).
    • 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 partial 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 (P&A Games):

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


Emulate protection in 7 e Mezzo (Unknown):

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


Hook the inputs properly in pmpoker.c games:

Connect all inputs through PIAs and remove the direct hack to input registers for all sets.


Rewrite the ltcasino driver:

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