EmuCR:WinUAEWinUAE v4.9.0 Beta 32 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 v4.9.0 Beta 32 changelog:
- HDIW blanking could get stuck in always-on state if VPOSW was written mid screen with out of range values. (Agony Psygnosis title screen become fully border color blanked if ECS)
- Wait 2 fields before updating visible screen after display parameter change. Hides glitches at the bottom of screen that can appear when last visible line is actually line 0 or higher. Direct 3D output is still refreshed normally, only difference is that data comes from old frame. Most "real" displays would either roll (CRT) or blank temporarily (LCD etc) in this situation.
- On the fly config changes are again checked and processed before vertical position 0 starts. Previous display updates moved it to line 1 or later, depending on mode. This might have caused unexpected side-effects.
- Hardwired vertical blanking didn't work correctly if OCS Denise was configured.
- Removed OCS Denise H-blank bug advanced chipset option. It is now always enabled (if OCS Denise configured) but "buggy" top and bottom line is only visible if overscan mode is Overscan+ or Extreme.
- Switching from some other config to/from ECS Agnus 512k/512k configuration where Agnus sees 1M chip RAM (Agnus sees upper half of chip RAM at usual $800000 address but CPU sees it at $c00000) didn't always change config correctly. For example loading statefile that uses ECS 512k/512k config when current config is OCS 512k/512k, didn't switch config correctly. (Very old bug)
- ECS Denise + EXTHBLANK=1: vertical blanking (display blanking only) is fully disabled.
- New undocumented feature: DIGHIGH bits 3 and 11 are vertical start/stop bit 11 in ECS Agnus. AGA replaces them with horizontal H0 bits. It is not documented in HRM ECS chapter documents them, officially V10 bit is highest (and even V10 is almost totally useless). VPOSR/W V11 does not exist and vertical counter is only 11 bits (0 to 10) which makes DIWHIGH V11 feature that makes no sense.
- CIA/CPU timing fix in b21 was partically broken.
- Programmed mode vertical display start/end calculation adjustments.
- Bitplane refresh slot conflict emulation was "too random". Internal behavior is still unknown. (First demo / Starline corruption if ECS)
- INTREQ write that clears interrupt(s) didn't use cycle accurate (delayed) code path. (La Weird / Cave)
- Vblank interrupt horizontal start was not adjusted to new custom chipset emulation (Spectre Party / Phenomena and others)
- VHPOSR was not adjusted to new chipset emulation (hpos=0 reads previous vertical line)
- CD32 NVRAM write that wraps around caused NVRAM file size to increase.
