UniPCemu build 2022/10/16 14:49 is now live!

A small update this time, fixing a few small architecture-specific bugs and SVGA DAC bugs and some app errors.

UniPCemu:

• Made static image disk creation able to create any size of disk.
• Made optimized IDE disk creation to create optimal geometries with minimized orphan sectors with a 1024 cylinder limit enabled.
• Added an option to the settings menu to limit HDD cylinder count when generating a disk image.
• Cleaned up some upper case characters displayed in the Settings menu.
• Fixed Compaq RAM to behave properly again.
• Improved default memory limits for XT 32-bit machines and unknown configurations to be 4GB.
• Improved default memory limits to 4GB and 8GB for architectures supporting that much RAM.
• Made the MMU capable of handling addresses past the 8GB barrier by compressing all 64-bit address requiring entries to a single entry when precalculated.
• Cleaned up modem linked list code.
• Cleaned up paging linked list code.
• Optimized physical memory address translation.
• Improved SC15025 ERPF bit to be keeping the DAC in command mode and ignoring invalid writes/reads to color registers and legacy VGA handling of them and turning off the command mode.
• Moved various files to the common emulator framework.
• Updated SDL2 to the latest supported version.
• Fixed packet server PPP magic number detection.
• Fixed the software port E9 hack command mode to detect invalid commands properly.
• Fixed MIDI voice counter overflow.
• Fixed ATA DMA info handling during reset.
• Protected CPU reset lines being raised from overflow.
• Updated the common emulator framework to the latest commit.

Common emulator framework:

• Cleaned up opened files linked lists.
• Moved various files from the UniPCemu project into the common emulator framework project.
• Added a function to check if the version of a linked SDL(2) library is new enough.
• Made the RDP direct input mode mouse speed fix also take the linked SDL2 version into account.
• Improved SDL2 RDP patch based on revision number.
• Made the various SDL2 hints upwards compatible.
• Fixed invalid SDL_HINT_TOUCH_MOUSE_EVENTS declaration for older SDL version upward compatiblity.
• Improved SDL touch mouse event filtering support.
• Made some more events SDL2 upward compatible.
• Improved the final SDL2 hint to use a proper priority with it.
