WinUAE v3.2.0 Beta 4

EmuCR:WinUAEWinUAE v3.2.0 Beta 4 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 v3.2.0 Beta 4 Changelog:
- RTG<>chipset mode switching didn't check if modes have different filter type (forgot to add when RTG filter support was implemented)
- 68020/030 prefetch pipeline b3 missing addressing mode implemented. Other adjustments: single word unconditional branch-like instruction (for example RTS) stop prefetches immediately but conditional single opcode always prefetch one extra word before stopping. Bcc.S (when not branching) and DBcc probably aren't exactly right yet.
- A2090 ST-506 support implemented.
- Note about existing configurations that use A590 XT support: drive type (SCSI ID/XT) must be reset.
- GUI default windowed mode window size (when it runs for the first time and size information is not yet stored in registry/ini) is now adjusted for high DPI screen. (Windows 8.1+ only). Previously default size was far too small on high DPI displays.
- Added "I am Windows 10 compatible" manifest entry, winuaebootlog.txt now shows correct Windows 10 version information.
- Cleaned up pfield_do_linetoscr() mess.
- Added support for AGA subpixel bitplane delays (lores pixel can horizontally scroll 4 shres or 2 hires pixels or hires pixel 2 shres pixels). Limit: only works if both odd and even planes have same subpixel scroll value (which probably is true practically in all situations)
- b1 sprite right border corner case broke SSCAN2 sprite horizontal duplication.
- x86 bridgeboard emulation! A1060 Sidecar, A2088 and A2088T currently implemented.

x86 bridgeboard information:
- Currently uses fake86 CPU core + PC support chip emulation. Selected because it was very easy to integrate. Possible future A2286+ emulation needs different CPU core.
- All jumpers emulated. (Required redesign of expansion GUI extra config)
- Amiga floppy drive DF2: and DF3: can be re-configured as bridgeboard PC drives A: and B:.
- Only 360k and 720k standard dos disk images supported.
- A2088T 360k/720k compatible drive supported. Floppy switch not implemented.
- A1060 and A2088 apparently only have 360k drive and BIOS support.
- BIOS ROM required. Searching for "A2088 BIOS" or similar should work... No BIOS ROMs
added to rom scanner.
- Not much real testing done. Boots from dos boot floppy, drive formatting and reading/writing works.
- x86 CPU speed is currently very randomly chosen speed.
