Misc ViRGE fixes.
Changes to memory mapping.
Changes to PCI handling.
Disabled 'AMI WinBIOS 486 PCI' due to incomplete chipset emulation.
Invalid GUS register reads no longer kill the emulator.
Seperated TGUI9440 and TVGA8900D implementations.
Modes > 8 bpp now handled more logically in SVGA core.
Fixed broken status window for most SVGA cards.
Masking of address on 'legacy' VGA memory ranges now handled better.
- No longer crashes PCem when remapping (mostly seen when changing resolution in Windows)
- Added PCI registers
- Added LFB emulation (PCI only)
- Source pattern modes now work correctly
- Vsync flag now emulated correctly
- Scrolling in accelerator modes now works correctly
Also disabled some debug.
Fixed ESP value on ENTER when page fault after first push.
Fixed execution time of IDE Set Idle command.
Fixed head number on FDC Read Sector ID command.
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
