X128 03/11/2024

• I've done some optimising of the audio pipeline (as well as implementing a very basic "sleep until activated" flag for the soundchips) and it's now quite playable at ~30,000 cycles/ms, in a friendly video mode. Although some beeper tunes really slow things down.
• The HiLow DataDrive emulation and all the video mode junk seems to have pushed it well above 8 MBs of RAM again.
• I may be reaching some hard limits, based on some of the design decisions I made 30-odd years ago. Optimising is getting more difficult now and I need a bit more speed to (properly) say it will run on a reasonable 486. Maybe adding support for something like the CMSLPT would make sense as a way of offloading some of the processing on a slower machine.

• Firstly, I have been collaborating with Cesar (ZEsarUX author) to get HiLow DataDrive support working. It has been going well, progress is quite good. Currently, the file format is basically a huge stereo WAV file, so some more work needs to be done to make things more manageable.
• Secondly, I ended up experimenting and added some support in x128 for just about every video mode in DOSBox... The code in x128 is capable of outputting to just about anything, although the added abstraction layer does slow things down a bit. (Lots of optimising required).
• I added EGA (200 and 350-line monitors, and 64K/256K configurations), CGA (RGBI), and Amstrad. After that I had a look at what's new.
