WinUAE v2.3.1 Beta 12

WinUAE v2.3.1 Beta 12 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 v2.3.1 Beta 12 changelog:
- emulate A3000 Fat Gary/RAMSEY configuration address space mirroring (no real world effect but I was testing m68k AROS ROM on my A3000 and noticed this mirroring)
- hrtmon 2.32->2.33 update
- hrtmon didn't work in cycle-exact modes
- MIDI device names are also stored in configuration file (overrides old style id numbers)
- in auto resize and center filter modes 1x/2x.. modifiers change window size
- manual filter configuration size adjustments added, saved to config file
- RTG: do not refresh area outside of bitmap if bitmap is smaller than RTG screen resolution (AROS does this)
- some read write-only custom register changes, bset (and other similar instructions) don't have previously read prefetch data appearing in data lines when reading (like most other instructions do), data is zero. This explains why buggy programs that for example bset #x,$dff096 don't mess up register contents too much. (Fixes Kefrens Party Intro by Wiz, coder thought that bset #10,$dff096 is the right way to enable blitter nasty)
- sample ripper ignored most samples (broken when audio emulation was rewritten in 2.3)
- topmost scanline was usually not visible in autoscale modes
- weak bit copy protected ipfs broke in earlier betas (only if using latest dll)
