WinUAE v1.6.2 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 v1.6.2 Beta 8 changelog:
- unaligned word/long accesses emulated (68020 always fetches aligned longs, two accesses required if for example word is fetched from address 3)
- emulate 68020 instruction cache logic as documented in 68020 manual, cache hits are free, cache misses require normal, possibly slow chip ram fetch
- approximate emulation of 68020 prefetch buffer, more compatible with self-modifying code
- very approximate 68020 MUL/DIV cycle usage added
- 68030/040/060 also supported in "020CE" mode. Not totally useless because this can mean more compatible HD installed games by switching between JIT and "CE" mode on the fly using uae-configuration. (switching between CPU types on the fly isn't very good idea..)
Note that 68020 "CE" is still too fast (CPU internal calculations are not counted yet) but this is 100x better than previously because memory fetches are emulated, too fast CPU chip memory accesses and too fast blitter was the most common cause for problems.
- CD32 drive command communication and interrupt handling rewritten, should now match real hardware (I think..) At least Brian the Lion CD32 works again..
- NTSC mode shouldn't jump anymore
- automatic vsync mode on the fly switching between 50Hz and 60Hz screen modes if refresh rate is supported, disable vsync temporarily if rate not supported (until switching back to supported rate)
- Superstardust AGA weapon panel breaks if 1 extra BPLCON0 delay cycle added. Obviously previous fix wasn't right.. Lets try something else, add extra cycle if first bpl dma cycle is allocated (8 planes)
