WinUAE v6.0.0 Beta 13 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:
- Denise side processing is now in separate thread (bitplane shifting, sprite shifting, bitplane/sprite planar to chunky, special modes, bitplane/sprite priorities, strobes/blanking, RGB out etc). Line-based Denise RGA buffering made this possible because it cleanly separates Agnus and Denise logic and Denise is almost fully "fire and forget". Only exception is CLXDAT collision register reads which needs to flush all queued lines (and isn't cycle-accurate yet anyway). AGA color reads don't cause problems because they are can be done in Agnus side emulation. Line queue is quite small (max ~10 lines), it won't cause any latency problems. Compatibility is not affected. (In previous UAE versions Agnus side processed whole frame, then Denise side did the rest which was not very optimal because temporary frame data needed huge RAM buffers)
- -nomt command line disables multithreaded Denise emulation.
- Previously always used temporary graphics buffering is only done if needed: display port adapter enabled (which also includes genlock in image mode, grayscale and CD32 FMV). This also increases performance. Only affects native chipset modes. When using display port adapter: complete chipset display frame is drawn to temporary RAM buffer, then display port adapter emulation merges it with any display port adapter graphics and writes the result to D3D texture. When this is bypassed, chipset graphics is directly drawn to D3D texture in single pass.
- Any enabled display port adapter (including genlock in image mode, grayscale or CD32 FMV) or enabled light pen disables non-CE border/bitplane optimizations.
- All software filters removed. Removal of always-enabled temporary graphics buffer makes software filter support annoying and they are obsolete anyway.
- b12 CE mode bitplane optimizations disabled (commented out), they are not needed anymore and they caused side-effects and glitches that are really difficult to fix completely without making optimizations useless. Non-CE mode optimizations are supported and will not be removed.
- Disable NTSC STRLONG strobe emulation if no STRLONG strobes have not been seen since last frame. Switching to NTSC and then back to PAL won't anymore cause slightly reduced performance (Accurate STRLONG emulation needs more complex line drawing code). NTSC still have right edge glitches on fast modes.
- Tiny blitter optimization.
- Adjusted non-fastest possible CPU mode frame waiting behavior (timing is different because now drawing is done after line has been emulated, in previous versions all lines were emulated first, then drawn in separate pass)
