Nothing listed here is a guarantee or promise of action. I have many more interests than I have hours in a day. This lists only things directly related to MAME. Also, order listed here may not reflect actual implementation order.


  • Fix controls in Prop Cycle now that it runs 100% on my system
  • Get C75 BIOS hooked up in all games (NB1/2 done, FL pending)
  • Merge submitted H8S core with our existing H8 core
  • Help Andrew with Polygonet Commanders where possible (I AM NOT A DSP56K COWBOY)
  • Continue to work with the SpriteMind guys on YM2612 improvements (new improvements coming in 0.128u1)
  • Final polish on the SH-2 DRC
    • Add final missing opcodes for Saturn
    • Add SH-1 with extra opcodes locked out, multiply instructions limited to SH-1's lower precision
  • SH-4 DRC for Naomi/Atomiswave (and Dreamcast in MESS)


  • Intel Xscale PXA255 CPU and peripherals so 39in1 boots now that Andreas has decrypted it (ARM9 plus MMU and peripherals)
  • SCSP/AICA DSP recompiler
  • 65816 family reunion
    • Merge 65816/M37710 so identical opcodes are used identically
    • Add Nintendo varient that runs in terms of SNES master cycles for better accuracy
  • Rewrite SNES renderer from scratch for better accuracy, including modern discoveries
  • Rewrite Konami video chain and trojan unclear details
  • Further reverse-engineering on (Super) System 23


  • Rework OpenGL backend:
    • Need to use a pixel shader to do YUV to RGB conversion or else laserdisc games will suck mightily on modern video cards (which no longer have dedicated conversion hardware)
    • Render to texture first so user shader can still be used for final blit? (And how bad will this break fglrx and Apple drivers?)
  • Improve GTK debugger so memory editing is possible
