==Near-term==
* "napple2gs" project
* Fix controls in ''Prop Cycle'' now that it runs 100% on my system
  - New clean, modern IIgs driver, running the ADB micro controller code (in progress)
* Help Andrew with ''Polygonet Commanders'' where possible (I AM NOT A DSP56K COWBOY)
  - Simulate 1 MHz synch slowdown (initially done)
* Continue to work with the SpriteMind guys on YM2612 improvements
  - Working IIe keyboard for simulated "upgraded IIe" (working)
* Final polish on the SH-2 DRC
  - Pass self-tests and diagnostics disk
** Add final missing opcodes for Saturn
* Emulate key repeat on Apple /// (similar to //e, same h/w designers, go figure)
** Add SH-1 with extra opcodes locked out, multiply instructions limited to SH-1's lower precision
* Break up Mac driver to better reflect h/w differences, and make the various system ASIC families into devices (in progress)
* SH-4 DRC
* Figure out Ensoniq 16-bit crash (EPS OS, VFX SD/SD-1 sequencer)
 
* Emulate 3rd-generation Ensoniqs (ASR-10, MR-Rack, KT-76)
==Later==
* Break out HLE'd line-level ADB handling into a bus/ and devices.
* SCSP/AICA DSP recompiler
* Get Lisa to run
* 65816 family reunion
* SH4 and ARM DRCs
** Merge 65816/M37710 so identical opcodes are used identically
* AICA needs better envelope handling. Shenmue DSF rips need filters
** Add Nintendo varient that runs in terms of SNES master cycles for better accuracy
* Cycle-by-cycle WDC65816, integrating M377xx and Nintendo variants
* 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
 
==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?)
* Improve GTK debugger so memory editing is possible
