==Near-term==
As of February 25th, 2026, things in progress for the relatively near future include:
* Merge submitted H8S core with our existing H8 core
* Continued SDL3 support
* Help Andrew with ''Polygonet Commanders'' where possible (I AM NOT A DSP56K COWBOY)
* 68k Mac ASC and pseudo-VIA improvements using Doug Brown's ASCTester
* Continue to work with the SpriteMind guys on YM2612 improvements
* Akai S2000/3000: fix clipping/static noise in sample playback and add flash ROM option card
* SH-4 DRC for Naomi/Atomiswave (and Dreamcast in MESS)
* Akai MPC2000XL/MPC3000: fix SCSI.  Add Zip drive and flash ROM option card to 2000XL


==Later==
A little farther out:
* Intel Xscale PXA255 CPU and peripherals so 39in1 boots now that Andreas has decrypted it (ARM9 plus MMU and peripherals)
* PowerPC: Obtain RISU testing data, and add an interpreter (should help both PowerMacs and e.g. Sega Model 3)
* SCSP/AICA DSP recompiler
* Get the preliminary Quadra AV driver and associated devices into mainline.  Real support will involve a DSP3210 core. The opcodes are largely the same as the DSP32 we already emulate but the binary encoding is different for no particular reason
* AICA needs better envelope handling.  Shenmue DSF rips need the filters.
* 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

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.

As of February 25th, 2026, things in progress for the relatively near future include:

  • Continued SDL3 support
  • 68k Mac ASC and pseudo-VIA improvements using Doug Brown's ASCTester
  • Akai S2000/3000: fix clipping/static noise in sample playback and add flash ROM option card
  • Akai MPC2000XL/MPC3000: fix SCSI. Add Zip drive and flash ROM option card to 2000XL

A little farther out:

  • PowerPC: Obtain RISU testing data, and add an interpreter (should help both PowerMacs and e.g. Sega Model 3)
  • Get the preliminary Quadra AV driver and associated devices into mainline. Real support will involve a DSP3210 core. The opcodes are largely the same as the DSP32 we already emulate but the binary encoding is different for no particular reason
