WinUAE v5.0.0 Beta 12 RC4

WinUAE v5.0.0 Beta 12 RC4 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 changelog:
- Integer scale in high overscan modes (Overscan+, Extreme and larger) used default native mode width/height, not selected overscan mode width/height.
- OCS Denise earliest allowed BPL1DAT access check (which was updated in b5) didn't disable border even if horizontal DIW was already open, previously earliest allowed was small enough to not cause this side-effect. (For example Seven Seas / Andromeda)
- Check that prevented unnecessary writes to same color register in same cycle (can happen in fast CPU modes) was not correct and in some situations triggered even in cycle exact modes (Hotbleeps / Loonies)
- Off by one in bitplane sequencer stopping due to DMA being disabled. (Denise test case)
- If bitplane DMA was disabled when it was in "ddfstop passed" condition and DMA was re-enabled in later line (which finishes "ddfstop passed" condition, stopping bitplane sequencer after single "block"): lower priority DMA channels lost cycles because they incorrectly saw bitplane DMA being enabled and active normally during whole scanline.
- Debugger sprite "sp" option now uses ECS height bits when outputting sprite pattern if mode is ECS or AGA.
- Blitter internal state after line mode had ended was not correct since 4.9.2+ (Cemetery Of Silence / Possessed)
- Loading new statefile when emulation was running and blitter was active: it was possible blitter got stuck in active state. I have noticed this many times randomly but I finally found repeateable test case.
- FloppyBridge write protection status in GUI is now mirroring drive floppy protection status. Previously it was always shown as write protected (checkbox disabled and ticked). This didn't affect floppy drive writing, it was only visual problem. Note that GUI write protection status is not updated in real time, it is only updated when selecting floppy drives GUI panel.
- b10 automatic scaling fix fixed. Last line was off by one if bitplane ended normally (vertical diw end matched), wrong check was changed (plane count become zero or DMA was disabled). Interlace mode had one extra line at the bottom.
- Autoscale filter modes horizontal positioning was randomly unreliable or jittery if switched from programmed mode (or Picasso96 with "hidden" 31KHz mode) to native mode.
- About, contributors and error log window DPI/GUI font scaling support.
- CPU panel slider refresh update, previously any slider move caused slider update which could have caused side-effects.
