Arbee's To-Do List

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.

Near-term

• Finish emulating DEC Rainbow's keyboard, try to boot MS-DOG
• Line-level ADB handling so Egret/Cuda equipped Macs have mouse and keyboard working (and IIgs and early PowerBooks when the ADB MCU is properly emulated) (UPDATE: working for Egret, timing isn't quite what Cuda's looking for yet).
• M50740-series core (6502 derivative) for IIgs ADB MCU / PMU on PowerBook 1xx when OG finished the new "perfect" 6502 family core
• nscsi-based NCR5380 and 5394/96 adaptations
• Help Andrew with Polygonet Commanders where possible (I AM NOT A DSP56K COWBOY)
• Continue to work with the SpriteMind guys on YM2612 improvements (if any)
• SH-4 DRC for Naomi/Atomiswave (and Dreamcast in MESS)

Later

• SCSP/AICA DSP recompiler
• AICA needs better envelope handling. Shenmue DSF rips need the filters.
• 65816 family reunion
  • Merge 65816/M37710 so identical opcodes use the same code
  • Add Nintendo varient that runs in terms of SNES master cycles for better accuracy
• Rewrite Konami video chain and trojan unclear details
• Further reverse-engineering on (Super) System 23
• Investigate 680x0 instruction restart
• ARM DRC

SDLMAME/MESS

• 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?)
