Download WinUAE 3.5.0

Version 3.5 of WinUAE has been released. This Windows port of the UAE Amiga Emulator is able to emulate a Commodore Amiga perfectly. All models, from the very first Amiga 1000 to the Amiga 4000, are supported. Keep in mind that WinUAE comes without kickstart, so to speak the bios/firmware of an Amiga, or other software. More information can be found on the support forum are being found. WinUAE runs on Windows 2000 and above, and the download is less than 6MB in size. Amiga Forever is a possible solution for a kickstart and programs, with prices starting at 10 euros. The following changes and improvements have been made in this release:

New emulated hardware

• Comspec SA-1000
• California Access Malibu
• DKB RapidFire
• M-Tec AT-500 Megabody

New features

• Soft float FPU emulation mode. Bit perfect FPU emulation (except transcendental functions), including full arithmetic exception support. (Co-operation with Previous emulator author)
• Lightpen emulation absolute coordinate HID (USB light guns) and touch screen device support.
• American Laser Games second player and Actionware dual light gun adapter emulation.
• Real hard drive mount lock option. Enables full exclusive access even if drive has Windows mounted FAT partition(s).
• winlaunch.lib is now built-in feature and is also 64-bit compatible.
• show [Paused] in windowed mode title bar when in pause mode.
• If statefile is loaded with one or more floppy images that can’t be opened: keep fake disk in drive (like previously) and ask for new disk path when missing disk is accessed for the first time.

Custom chipset features emulated

• AGA FMODE>0 unaligned bitplane and sprite pointer behavior implemented, resulting display corruption is now 100% accurate.
• BPLCON4 XOR mask special case in HAM6/8 or EHB modes.
• Loading blitter B-DAT manually when B-shift was nonzero.
• Lightpen hardware is now cycle-exactly emulated.
• Sprite special case when DMA mode sprite’s start X-coordinate is less than sprite’s DMA slot position.
• Audio interrupts are delayed by 2 cycles.

Feature improvements

• 68020+ T0 trace mode is now fully emulated.
• 68020 cycle exact mode adjustments.
• Memory cycle exact mode mode accuracy improved
• Implemented previously unimplemented bsdsocket.library emulation sendmsg() and recvmsg().
• Recursive mode ROM scanner now skips directories starting with dot.
• MMU emulation can be now switched on/off on the fly.
• Release all currently pressed keys when emulation pauses.
• Added memory cycle-exact Quickstart step for A1200 and CD32 configurations. Less CPU heavy than full cycle-exact and usually not much more worse (or better). At least not until 68020 CE gets better.
• Escape old style directory and hardfile paths if it contains “,”.
• Masoboshi MasterCard fully implemented, including DMA support.

Bug fixes

• FM801 16 bit audio corruption.
• A2090 ST-506 emulation.
• Possible crash when display was very wide with bitplane DMA overrun condition.
• Fixed crash when sound card audio play started and channel mode was mono and “Include CD and FMV audio” was ticked.
• Fixed crash when accessing accelerator board SCSI IO region without any added SCSI device(s).
• Fixed crash if Blizzard accelerator on board memory size was set to zero.
• JIT was not 512k or 1M Chip RAM compatible.
• Manual RAM configuration GUI didn’t accept smaller end address than current board size.
• Manually configured but disabled (size zero) Z2/Z3 banks were added to system.
• Apollo 1240/1260 memory address space fixed
• PC bridge board NE2000 boot crash fix.
• Windowed mode mouse does not anymore hit hidden barriers if window is partially outside of desktop or uncaptured if window is on top of task bar.
• If Custom autoconfig board order was enabled, expansion devices custom config setting(s) was not saved correctly.
• 68000 address error stacked PC was not correct in some read-modify-write instructions
• Untrap middle mouse button option was stuck.
• GUI listview column width calculation used default font size, not selected font.
• 68030 CE/prefetch mode cache access bug fixed.
• G-REX and Cirrus Logic graphics board state was reset if RAM or HW Info GUI panels were opened after emulation was started.
