Changes since v0.7 :
- Major CPU reorganisation. This has possibly broken some stuff, though I fixed all the regressions I could find
- Lazy flags. This brought 10% speed improvement at one point, but that's probably been lost now
- 430 VX chipset emulation
- IDT Winchip emulation (currently sans MMX). Timing is probably wrong
- Fixed a few FPU bugs
- Timer reorganisation
- Sound reorganisation
- Other general reorganisation
- AdLib Gold emulation
- Windows Sound System emulation
- Pro Audio Spectrum 16 emulation. This currently works with most DOS stuff, but not in Windows
- Major improvements to GUS emulation. Has the downside that it now conflicts with SB emulation, so probably best to not enable both simultaneously
- New graphics cards :
  - ATI-18800 (VGA Edge-16)
  - ATI-28800 (VGA Charger)
  - ATI Mach64GX (Graphics Pro Turbo). Quite a few features missing, but Windows doesn't seem to use half the features of this card
  - Cirrus Logic CL-GD5429. Blitter is a bit broken
  - Oak OTI-067
  - S3 Trio64 (Number Nine 9FX)
  - S3 Virge. Only framebuffer stuff at the minute, Windows won't recognise the card
  - Trident TGUI-9440
  - VGA. Doesn't work yet
- Beginnings of 3DFX emulation, however this is in extremely early stages and doesn't do anything useful
- Fixed DMA bug stopping floppy drives working in Windows 3.x
- Fixed some other stuff probably
- Broke some other stuff probably as well
