WinUAE v3.3.0 Beta 1 is released. WinUAE is the commodore amiga emulator for Windows. WinUAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. A Commodore Amiga, for those who don’t know, is a 16/32 bit computer system based on the Motorola 680×0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. WinUAE is a port of the originally written for Unixish systems UAE; but over time, it seems the Windows port, WinUAE has become the best version available on any platform. WinUAE is free software: you are welcome to distribute copies of it and/or modify it, under certain conditions. There is no warranty of any kind for UAE. For more details concerning these issues, please read the GNU General Public License, which describes the terms under which WinUAE is distributed.

WinUAE v3.3.0 Beta 1 Changelog:
* Added extra validation checks for STORAGE_DEVICE_DESCRIPTOR, buggy drivers may return invalid (negative) offset values.
* 64-bit JIT harmless "Warning! 12 is locked" log spamming disabled.
* Updated copper/blitter cycle conflict emulation. It only triggers when CPU writes to COPJMP, Copper is waiting and Copper DMA is enabled (and blitter uses same cycle). If Copper DMA was off, bug won't trigger, even if DMA gets
* enabled few cycles later. Copper bug emulation is again always enabled if 68000 and cycle-exact config.
* Cancel main thread sleep state immediately (Sleep due to CPU idle or similar) if PPC thread caused mainboard interrupt. This should reduce PPC to M68K interrupt emulation latency.
* Hardware RTG emulation rendered same frame twice in some situations. Caused very slow performance in triple buffered mode.
* Debugger keyboard presses were buffered and output to Amiga-side when debugger was exited.
* Starting disk DMA does not flush Paula internal 16 bit buffer. Poll DSKBYTR for DSKSYNC, immediately start disk DMA with WORDSYNC enabled: following sync word must not be missed. (Original Virus really slow loading in cycle-exact mode)
* Chip ram was marked as 16-bit Fast RAM for the CPU (no DMA contention emulation) if any memwatch point was active.
* Amithlon partition type (0x78/0x30) support was broken, partitions were detected but it was not possible to mount them.
* Added SX32 Pro board and ROM image. (Not all RAM sizes are correctly mapped)
* Only unmap Z3 Fast RAM at reset if Z3 mapping mode is "Real" for better compatibility with old configs that assume Z3 RAM does not temporarily disappear at boot.
* JIT on/off on the fly change without other CPU settings changed at the same time with uae-configuration didn't work.
* Hardware emulation autoconfig board UAE interface first working feature: uae-configuration now works under OS4 Requires also updated uae-configuration, interface can also work under other non-m68k AmigaOS operating systems, only requirement is simple native uae-configuration port. Interface design is not final yet.
* If CSPPC or BPPC is booted with empty or zero size flash rom image, fake resident idtag is automatically added that fools official flash rom updater to detect working board, "updating" the empty flash with full image (updater contains full flash rom image in encrypted format)
* Debugger memwatch points can now match only CPU instruction (CPUI) or only CPU data accesses (CPUD, CPUDR, CPUDW)
* "Heat map" debugger added, shows optional visual heatmap of CPU and DMA accesses. Can list highest addresses used by CPU instruction fetches or all addresses that single device accessed (Some DMA channel, CPU)
* Some AGA modes were incorrectly detected as bitplane DMA overrunning causing screen corruption.
* AROS ROM updated.
