WinUAE v4.9.9 Beta 10 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 v4.9.9 Beta 10 changelog:
- Bumped version to 4.10.0
- 64-bit natmem limit increased to support G-REX PCI VRAM modification detection (Only draw lines that have been modified). Previously Voodoo 3 + G-REX always forced whole screen refresh. G-REX PCI memory space is above 2G "limit". Check also current limit to prevent "picasso_getwritewatch 87" log messages when running 32-bit version.
- SupraDrive AMAB5 and AMAB6 are also 8k. Removed extra duplicated 8k. Previous SupraDrive 2000DMA ROM is called "44-25B" (Hand written text on ROM label did say 44-25B but I thought it was some kind of checksum or something but SupraRomChk on SupraBoot3.8B install disk does detect it as "44-25B"). Updated 2000DMA ROM mapping, SupraRomChck now detects supported ROMs correctly. Remaining undumped official Supra ROMs are "33-11B" and AMAB1, listed inside SupraRomChk executable. (Also some AMAB5 and AMAB6 beta roms are listed)
- Added Hardital Synthesis/Super Big Bang v48.5 (previous was v53.1)
- Serial port ring indicator (RI) signal support (RI is shared with printer port SELECT line)
- Fix out of bounds buffer access when checking what should be written to write-only register that was read. (b5)
