EmuCR:WinUAEWinUAE v4.9.9 Beta 7 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 7 changelog:
- Interlace mode filter crash fix (b5).
- Disk read DMA started (without DSKSYNC) and reading "nothing" (no drives connected): disk DMA never finished. (CDTV boot hang without DF0:)
- CIA B timer counting timer A underflows or CNT: generated interrupt was 1 timer count too early.
- 68060 without FPU and executing FPU instruction that uses -(an) or (an)+ addressing mode: address register's original value was restored twice when F-line exception stack frame was being created. Second time it used invalid register value causing D7 to be modified.
- Audio interrupts and AUDxDAT processing delays fixed. They were too long (2 CCK) when correct delay is only 1 CCK. 2 CCK appeared to be correct because previously interrupt timing was wrong.
- Keep CPU halted when keyboard reset keys are kept pressed. (b3 reset change update)
- EHB mode was unreliable in AGA mode (b5)
- 68010+ BKPT illegal instruction exception had stacked PC pointing to next instruction but it should point to BKPT.
- 68010 DIVU overflow condition undefined N flag behavior updated. (DIVS overflow undefined flags are still not fully correct)
- Copper/blitter bug tested, updated and confirmed and is enabled by default again (only if 68000 and cycle-exact). This is the infamous chipset bug that can cause copper pointer to blitter pointer copy if copper was waiting, CPU wrote to COPJMPx during odd cycle and blitter was active. Not 100% accurate (modulos are not added correctly when glitch happens) in line mode because line mode internal "micro-operations" are not fully correct (exactly when pointers change, modulo is added etc, invisible operations that don't affect line mode output).
