PC Bridgeboard (A1060 Sidecar, A2088, A2088T, A2286 and A2386SX) emulation rewrite: - Emulation core replaced with PCem. Compatibility has improved greatly, for example Windows 3.x enhanced mode, DOS extenders and Windows 95 are now fully working - Bridgeboard built-in CGA emulation graphics corruption fixed - A2386SX VLSI chipset memory remapping, shadowing and EMS fully supported - Cirrus Logic emulation PC compatibility improved, 2M VRAM, linear frame buffer and blitter support - PC Speaker emulation (PCem) - Sound Blaster emulation (PCem, various models) - Serial mouse emulation (PCem) - SCSI adapter emulation (Rancho Technology RT1000B) Other updates: - AGA hires/superhires horizontal pixel positioning and borderblank horizontal single hires pixel offset fully emulated. Optional because it requires much more CPU power and it is rarely needed. DIWHIGH H0/H1 AGA-only bits emulated - AGA FMODE>0 undocumented features implemented (BPLxDAT, SPRxDAT CPU/copper accesses, bitplane modulos that are not integer divisible by fetch size) - Added new misc option which captures mouse immediately when windowed/full-window winuae window is activated - 68030 MMU emulation compatibility improved - Paula disk emulation GCR MSBSYNC support added (Alternate Reality protection track) - Added quick search and quick directory select to Configurations panel. Link and autoload moved to Advanced information panel - Added history list to config file name edit box and to statefile path string box - Added vertical offset option to D3D scanlines - 64-bit version didn’t support 64-bit unrar.dll - 68030/040/060 with data cache emulation but without enabled MMU emulation: force Chip RAM as non-data cacheable - Magic mouse Windows cursor to Amiga mouse sync partially fixed - Window corners now work as drag’n’drop hot spots for different floppy drives. (top/left=0, top/right=1, bottom/left=2, bottom/right=3) Bug fixes: - 68020 + memory cycle exact hung the emulator in some situations - Reading CIA interrupt status register in a very tight loop generated spurious interrupt(s) in certain situations - Softfloat mode with unimplemented FPU emu ticked didn’t disable 68040/060 unmasked interrupts, confusing 68040/68060.library and possibly causing it to return incorrect values - Some CHD CD images didn’t mount correctly - uaehf.device HD_SCSICMD didn’t set scsi_SenseActual. Also set io_Actual=30 (=sizeof(struct SCSICmd)) - If config file had KS ROM path/file that didn’t exist, it was replaced with non-existing ../system/rom/kick.rom path or was not correctly fixed with valid path - NCR53F94 SCSI chip emulation DMA counter fix (affected for example Blizzard SCSI Kit) - Very large directory harddrives returned halved used/free space - Fixed multiple problems with screenshots and video recording from hardware emulated RTG board - Filter panel scanlines work now correctly in multimonitor mode - Crash fixed if more than one non-Paula audio stream was active. Included emulated sound cards, also CD audio if “include” option ticked - NE2000 PCMCIA and NE2000 bridgeboard didn’t support custom MAC and network mode selection - Fixed hardware emulated graphics board hang with Picasso96 if board supported vblank interrupts and RTG board refresh rate mode was not Chipset - Fixed statefile crash when saving statefile while disk operation was active and disk image included bit cell timing information Bug fixes (Introduced in 4.0.0/4.0.1): - Display port adapters that needed genlock transparency data (FireCracker, HAM-E, OpalVision, ColorBurst) didn’t work correctly since 4.0.0 - Display port adapters didn’t work in multimonitor mode - Blitter statesave with blitter active: log window opened and listed few lines of blitter debug information - Some programs caused continuous flood of “blitter is active, forcing immediate finish” log messages - CTRL+F11 quit ignored new “Warn when attempting to close window” option - 68020/030 more compatible/cycle-exact mode statefiles didn’t always restore properly Bug fixes (Introduced in 4.0.0/4.0.1): - CSA Twelwe Gauge (A1200 68030 accelerator + SCSI controller) - AccessX/Acetec IDE controller
