==Near-term==
* Fix 539X issue with Mac Quadra 700 and upgrade to working
* <s>Fix controls in ''Prop Cycle'' now that it runs 100% on my system</s>
* Twiggy Mac, Lisa
* Get C75 BIOS hooked up in all games (NB1/2 done, FL pending)
* More 030/040 Macs - need to figure out feasibility of PMUv4 (68HC05) emulation
* Merge submitted H8S core with our existing H8 core
* Emulate key repeat on Apple /// (similar to //e, same h/w designers, go figure)
* Help Andrew with ''Polygonet Commanders'' where possible (I AM NOT A DSP56K COWBOY)
* Figure out Ensoniq 16-bit crash (EPS OS, VFX SD/SD-1 sequencer)
* Continue to work with the SpriteMind guys on YM2612 improvements <s>(new improvements coming in 0.128u1)</s>
* Emulate 3rd-generation Ensoniqs (ASR-10, MR-Rack, KT-76)
* <s>Final polish on the SH-2 DRC</s>
* ARM DRC
** <s>Add final missing opcodes for Saturn</s>
* AICA needs better envelope handling.  Shenmue DSF rips need filters
** <s>Add SH-1 with extra opcodes locked out, multiply instructions limited to SH-1's lower precision</s>
* Cycle-by-cycle WDC65816, integrating M377xx and Nintendo variants
* SH-4 DRC for Naomi/Atomiswave (and Dreamcast in MESS)
 
==Later==
* 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
 
==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
