Emulator: Preview to WinUAE 3.5.0
As usual the developers of the well-known Amiga emulator WinUAE present a short preview to the changes of the next version. WinUAE 3.5.0 is supposed to be released in the middle of June and will provide the following improvements:

New features:
  • Softfloat 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 harddrive 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.
New emulated features of the chipset:
  • AGA FMODE>0 unaligned bitplane and sprite pointer behavior is now 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.
Improvements of existing features:
  • 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.
Fixed bugs:
  • 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 bridgeboard 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.
