WinUAE v4.9.9 Beta 8 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 8 changelog:
- RTG to chipset mode (non-interlaced) switch didn't enable native mode filter (b7)
- If CIA-A TOD counting was PSU tick based, ticks that were delayed until next scan line (due to CIA internal TOD counting delays) were lost. (b1)
- Added GVP A1208 Z2 RAM + SCSI board. It is basically GVP Series II Z2 SCSI controller + RAM expansion in different form. Uses usual GVP Series 2 SCSI ROMs. If A1208 is emulated and Z2 RAM is enabled, Z2 RAM gets GVP A1208 Z2 RAM autoconfig data. A1208 GVP internal device ID is 0x97.
- JIT mode interrupt handling restored, JIT needs "different" interrupt handling than non-JIT modes for best performance. (b5)
- uaegfx blitter emulation was accidentally disabled since b4.
- uaegfx b1 update had wrong operator in masked 8-bit DST=SRC blitter function (Turbotext scrolling in 8-bit) (b1)
- uaegfx non-basic blitter functions (for example mask set or not commomly used) didn't handle overlapping source and destination correctly. (Turbotext scrolling in 8-bit mode)
- gfx_left_windowed and gfx_top_windowed config file entries replaced with gfx_x_windowed and gfx_y_windowed. Reason was swapped coordinates but to keep backwards compatibility, new config entries have been added instead of fixing it by swapping them. Old config entries still work.
- A4000 Quickstart mode set PSU tick CIA-A TOD timing but A4000 does not have PSU tick hardware.
- 68020 cycle-exact timing adjustment (Lionheart whdload slave v2.3)
- Increased A1200 68020 approximate speed slightly. (Many AGA demos had slowdowns). CE mode is not changed.
- Rare SupraDrive 2000DMA boot ROM was finally dumped. Support added.
- Debugger memwatch command parsing changed. Some parameters got skipped. Value match is now V.
- Debugger string to integer parser error condition support added. Potentially dangerous commands are now aborted if expected address can't be parsed (like 'g '), previously failed string to integer conversion returned zero value.
