UniPCemu build 2018/09/14 19:25 is now live!

Mainly two improvements have been added for this update:

• ATA/ATAPI drives have been fixed and work better(including OAKCDROM.SYS, which now works!).
• The ET4000 graphics card has improved and has fully fixed SVGA graphics modes. All modes that run with 1MB memory on WHATVGA give correct output now.

Full changelog:

• Improved ATA/ATAPI signatures missing device/head register.
• Implemented ATA/ATAPI power on reset signature.
• Fixed ATA/ATAPI signature when resetting a ATA/ATAPI controller.
• Improved ATAPI read sectors and Identify command result error register.
• Improved Abort reporting on ATAPI devices.
• ATA/ATAPI Sector count register always exists!
• Improved ATA/ATAPI error reporting to be more correct.
• Improved ATA/ATAPI SRST keeping the device busy and not ready.
• Implemented missing ET3000/ET4000 Sierra Hi-color DAC support for the internal video BIOS.
• Added support for hi-color DAC to the internal video interrupt pixel plotting support.
• Improved pixel plotting documentation of the video interrupt.
• Improved supported ET3000/ET4000 modes.
• Added high-color mode tests on ET3000/ET4000 graphics cards.
• Improved finishing the Sierra Hi-color register back to it's default mode when setting up 32K/64K color modes.
• Updated the common emulator framework to the latest commit.
• Improved VGA graphics test color range.
• Fixed debugging graphics mode size.
• Improved higher VGA mode tests.
• Improved internal video BIOS support for higher VGA modes.
• Fixed priorities in ET3K mode switches in the internal video BIOS.
• Improved 16-bit DAC rendering to work properly on two clocks.
• Improved DAC supporting both 8-bit and 4-bit pixel merging into 8-bit/16-bit pixels.
• Improved pixel doubling during advanced DAC rendering.
• Fixed code typo.
• Simplified bank selection on Tseng graphics cards.
• Improved ET3K/ET4K Chain-4 to also enable the 8-bit graphics mode.
• Improved ET3000/ET4000 linear byte mode to ignore the plane write mask and Read Plane Select(unused atm for this case) when set.
• Improved ET3000/ET4000 odd linear mode using byte addressing mode always.
• Fixed typo.
• Updated SVGA to perform 8-bit clocking correctly.
• Improved Dot Clock Rate on linear byte mode.
• Prevented unwanted 8-bit pixel doubling on Tseng hardware.
• Fixed code issue.
• Improved ET3K/ET4K linear graphics clocking.
• Fixed the renderer to perform ET3K/ET4K according to the new method.
• Fixed code again.
• Fixed applying Dot Clock Rate.
• Modified Dot Clock Rate to behave non-stacked, also depending on the emulated graphics card.
• Made DCR dependent on extensions being enabled on the ET3000/ET4000.
• Fixed (S)VGA linear mode and Dot Clock Rate.
• Improved linear mode detection to be more accurate.
• Improved byte/word/doubleword mode on ET3K/ET4K.
• Improved video rendering limits to be applied.
• Linear mode always renders the pixels unmodified, without space in between.
• Fixed higher scanline range to be the proper range when rasterizing the logical VGA scanline.
• Fixed ET3K/ET4K CPU window bank switching working properly again on Odd/Even mode and Planar mode.
• Removed all read/write bank shifts and offset masks(allow past 64K).
• Fixed (S)VGA preset row scan register handling.
• Made interlacing simply double the amount of pixel rows.
• Reimplemented interlacing as it used to be.
• Fixed duplicate variable.
• Fixed ET3K/ET4K updating of DCR and linear mode.
• Disabled interlacing effect completely.
• ET4000 KEY doesn't prevent precalcs.
• KEY does prevent the Segment Select register from being written.
• Code bugfix.
• Cleaned up code.
• Fixed CRTC protection.
• Improved ET3K/ET4K precalcs pixel shift count to apply better when required.
• Improved ET3K/ET4K register extensions to shift correctly.
• Improved seperated read/write banks in the ET3K/ET4K.
• Implemented ET4000 banking bit shift according to documentation.
• Added information dword for debugging rendering of SVGA.
• Fixed a bug in the GPU testsuite.
