Emulator: Preview to WinUAE 3.6.0
As usual Toni Wilen, the developer of the well-known Amiga emulator WinUAE, presents a short preview to the changes of the next version. WinUAE 3.6.0 is supposed to be released in January and will provide the following improvements:

Core emulation updates:
  • 68030, 68040 and 68060 full instruction and data cache emulation, with or without MMU emulation.
  • 68030, 68040 and 68060 EC model partial MMU (transparent translation registers only) emulation.
  • 68030, 68040 and 68060 MMU emulation performance improved (added extra translation caches).
  • STOP-instruction CPU model specific undocumented behavior emulated when parameter does not have S-bit set.
  • 68020+ DIVS/DIVU CPU model specific undefined overflow condition N and Z flags emulated.
  • Undocumented 68881/68882 FMOVECR values emulated.
  • Optional Toshiba Gary slow (chip ram like) Z2 IO and/or ROM space access speed.
Emulated hardware expansion updates:
  • Added Cubo CD32 later revision hardware support, PIC copy protection, touch screen, NVRAM and RTC emulation. (TODO: Coin and ticket dispenser support, no hardware information available)
  • Cubo CD32 is now expansion device, added DIPs, PIC game ID/language and expansion device enable options.
  • A2090 Combitec and MacroSystem 3rd party ROM update/adapter supported.
  • DKB 1230/1240/Cobra and Rapidfire flash rom writes emulated.
New emulated hardware expansions:
  • Ashcom Addhard (SCSI)
  • Evesham Micros Reference (SCSI)
  • FastATA 4000 MK I/II (IDE)
  • Gigatron Arriba (IDE)
  • Kupke Golem HD3000 (OMTI)
  • Reiter Software Wedge (OMTI)
  • Sprit Technology InMate (SCSI)
  • Music Master dongle
Direct3D 11 support implemented:
  • Requires Windows 7SP1 and later. Windows 7 requires KB2670838 (Available via Windows update as an optional update), Windows 8 and later does not need any extra packages. Ancient DX9 redistributable is not needed.
  • Requires hardware level 9.1 or higher, which means most Windows 7 capable GPUs are supported.
  • All Direct3D9 mode features supported (overlays, masks, custom shaders)
  • Variable sync (G-Sync, possibly also FreeSync) supported in windowed mode.
  • Many D3D9 custom shaders are supported automatically, some require manual modifications to work in D3D 11 mode.
Other new features and updates:
  • Simple box art/screenshot config file support.
  • If Wait for Blitter is enabled and blit size makes no sense, don’t wait. Fixes long delay in Vital / Mystic.
  • Added “CIA 391078-01” advanced chipset checkbox. This CIA revision has a bug in IO port output mode, reading output mode port will always read output mode data state. Other models, including original DIP 8520, 391078-02 and Akiko internal CIAs read IO pin external voltage level as documented. This can affect “bad” mouse left button/joystick fire button reading code (not working or stuck button). Used in A600. A1200/A4000 can have -01 or -02 revision.
  • Added ATAPI Tape drive emulation.
  • CD SCSI emulator READ CD-DA and READ CD-DA MSF commands emulated.
  • Expansion device GUI changes are now activated after hard reset.
  • uaehf.device hardfiles/harddrives unit number is now user configurable.
  • “Include CD and FMV Audio” and/or sound mode change on the fly when CD or FMV audio is playing is now supported.
  • Debugger assembler support (a) and some other misc debugger updates.
Bugs fixed:
  • It was not possible to override Z2 RAM board autoconfig data if board had built-in manufacturer/product ID defaults
  • It was not possible to change existing path with Select Directory/Select Archive or Plain File buttons.
  • Fixed 64-bit version random crashes that usually happened with some shell extensions.
  • Z3 RAM in manual mode was completely broken.
  • KS 1.2 autoboot hack didn’t work without extra reset if UAE autoconfig board wasn’t first board in autoconfig chain.
  • 68030 data cache emulation corrupted data if write was cached, write size was word or long and address was odd.
  • ECS Denise BPLCON2 ECS-only bits (for example KILLEHB) were masked unless AGA was also selected.
  • Obsolete IDE FORMAT TRACK command fixed.
  • GamePorts panel custom mapping incorrectly parsed joystick autofire state from config file.
  • Directory filesystem ACTION_SET_DATE failed to change datestamp if file was read-only.
  • 68020 memory cycle exact CPU speed slider is again partially working, CPU speed can be reduced but not increased.
  • GamePorts panel custom mapping incorrectly parsed joystick autofire state from config file.
  • uae-configuration joystick port (joyportx) modification only queued but didn’t apply changes.
  • uaeserial.device crash fixed.
  • Fixed uaegfx VRAM size check, some modes that almost filled whole VRAM didn’t appear in resolution list.
  • uaenet.device didn’t close low level ethernet handles when Amiga was reset, causing duplicate packets.
  • Bitplane overrun condition triggered incorrectly in rare situation where bitplane DMA is enabled after DDFSTOP on OCS
AVI recording bug fixes and updates:
  • First avioutput recorded frame was sometimes partially corrupted.
  • When saving state with avioutput active: last frame before state save was not recorded.
  • Number of avioutput frames buffered (waiting for compression thread processing) counter was reset periodically which caused lost frames (and leaked memory) in recorded video if CPU was not fast enough.
  • Delay initialization until first display frame or sound buffer recording request comes, previously “before filtering” option may have used wrong display size in some situations.
  • Uncompressed video selection is not forgotten anymore.
  • First frame was not rendered (and also not recorded) if statefile was restored when emulation was already running.
  • If emulator state was changed (debugger breakpoint, statefile save etc..), last frame before state change was not recorded.
  • File splitting (2G limit) flushed sound buffers causing random sound glitches.
  • Added -max_avi_size <bytes> -command line parameter to set split size.
  • If recording was started and GUI was never opened in same session, sound recording rate become 44100Hz, causing syncronization issues if real rate was not same.
