1. The SPEA specific cards using the 801/5 chip apparently have an ID that's not 0xa0, rather, they either use 0xa2 or greater for the stepping. Fixes wrong colors in 800x600 modes and greater in 8bpp mode.
2. HWCursor addresses for 8bpp are now properly implemented if the 8bpp mode bit (CRTC3a bit 4) is checked, no longer relaying on GDCREG5 bit 6). Fixes garbage cursor in the SPEA 80x cards drivers (BigWin) using 8bpp mode.
S3 side:
Temporary changes to match the release (due to tomorrow) of 86box. Said changes are about the horizontal display of the tvp3026-based S3 chips.
IBM/ATI 8514-based:
Temporarily commented out the hblank side of it due to htotal bugs.
TVP3026 side:
When the upper clock selection bits are 0 and when extended VGA modes are set, double the hdisp.
* Fix duplicated logic in vid_svga.c
* Voodoo 3/Banshee emulation now has blanking extensions applied
* S3 ViRGE and Matrox video cards as well
* Tseng ET4000-series cards as well
* Fix off-by-one error in vid_cl54xx.c
Trident cards are yet to be investigated. XGA and 8514/A are yet to be made blanking extensions compliant. Mach64, Paradise/WDC and OAK OTI cards remain as-is for now.
1. Moved the wraparound fix to the respective recalctimings, makes Commander Keen still playable without flickering and, at the same time, making Solaris work right in 640x480x8bpp+ mode (including 1024x768x8bpp).
2. The multifunction index 0x0e bit that can be toggled in 32bpp mode is now initialized properly, should fix the pinkness on Solaris' 32bpp mode.
1. Made the 924 BIOS use the AT&T 491 ramdac since it supports such (tested).
2. Tweaks to the 928 Brooktree ID detection to make sure the cursor is shown correctly in 16bpp+ modes (it uses the BT485 ID detection so that it knows what BT is using to accommodate the cursor model).
3. Refactored the mode (CRTC50) and pitch timing stuff (moved to recalctimings for example) so that drivers/games/operating systems and what not can be used normally. (Warning, more stuff is to be tested due to a gazillion of combinations used by said stuff).
4. VRAM wraparound is now working as it should, fixes Commander Keen games.
5. Indentation fixes.
6. Attempt to fix 15/16bpp mode acceleration used by the 911/924 chips (not perfect and still has bugs).
7. Added the remaining missing stuff of the Sierra SC1502x RAMDAC including its 8BIT setting.
8. Some drivers use FIFO bits in non-FIFO configurations, should fix hang ups in some instances (namely the 928 S3 2.3 NT 3.1 drivers and possibly more).
9. Separated the 911/924 acceleration from the 80x/928+ one though the use of a function pointer.
10. Fixed the inverted colors in some instances using the S3 Trio64 driver in Win9x (mainly on soft reboots).
11. CX/CY (non-Blits) and DX/DY (Blits) wraparound correctly during their respective operations, fixes OS/2 software cursor once again while keeping existing stuff working.
12. Added some comments to keep track of some anomalies.
13. Fixed some badly formatted if's and switches.
14. Limited the SPEA Mercury Lite VRAM to 1MB per real world configurations.
Bit 11 of ports 0x82e8 and 0x86e8 (Current X and Current Y positions registers, respectively) are taken into account again without conflicting with OS/2 Warp 3/4's software cursor, fixes blitting issues with Neptune Build 5111.1's S3 driver and possibly some other builds and other stuff.
