WinUAE v4.10.1 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 changelog:
- Added continuous screenshot mode to GUI (Was previously available via input events). When ticked, screenshot is taken automatically every frame.
- Fixed video recording and continuous screenshot including extra blank frame when loading new statefile. (4.9.0)
- Fixed second frame appearing corrupted after loading statefile due to not re-initializing long/short frame internal variables at startup (only visible in video recording or screenshot). (4.9.0)
- If game controller was configured using Game Ports panel (Custom #x setting) and device didn't have any Input panel mappings, config file input device matching with currently installed input devices was not done. This meant if config was moved to other PC, device specific input config was not loaded correctly. Now it also matches devices using only USB VID and PID if better match is not found. (Full match -> Partial match -> VID+PID only if exists -> Device friendly name)
- If config file has input device that is not currently connected, saving the config file didn't save non-connected device's config data. Now it is saved (like it was supposed to already do)
- Game Ports panel custom settings were not corrected automatically if device indexes changed (new input devices connected or removed)
- If Game Ports custom setting has entries that don't map to any currently connected device, show unmapped events as "=?" instead of showing nothing.
- CALLM disassembly fixed.
- 68030 MMU state was partially reset when loading statefile.
- If fast CPU mode program writes to color registers (usually COLOR0 to create background color rainbows), skip write if previous write already happened in same chipset cycle. This could have overflowed buffer that stores state where and when color change should happen in rendering part of emulation. Fast CPU modes don't slow down CPU by emulating chipset or chip ram delays.
- Reduced size of sprite buffers (which was huge), buffer size was enough to have whole screen filled with sprites in max superhires/800 lines screen mode which can't happen.
- "uae-configuration statefile_save " can be used to create statefile (note that save happens when vblank starts next, it is not saved immediately but uae-configuration still returns immediately)
