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
