6c631adc7e Added quick hack to FCOMPP to fix 80387 detection. Quake (and presumably some other stuff) works in Windows again. 2013-12-15 15:41:29 +00:00

7671f1e90d FPU opcode 0xd9 0xd8-0xdf are aliases for FSTP1. Doom v1.0 now works when FPU enabled.
Fixed TAG manipulation on several instructions.

af6d9474e6 FPU opcodes 0xd9 0xd8-0xdf, despite being undefined, do not throw an illegal instruction exception. Eradicator now works. 2013-08-24 15:11:30 +01:00

119fe36820 Added MMX emulation (probably some bugs). Implemented RDMSR/WRMSR for Winchip. 2013-08-03 15:05:50 +01:00

a479b55cc9 Fixed value of TOP when using FSAVE/FRSTOR. Infinity and NaN should now be preserved when loading/storing 80-bit floating point. 2013-07-07 12:05:53 +01:00

9312de19ac Now up to date with current dev version.
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
