WinUAE v2.3.1 Final 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 2.3.1 released (26.02.2011) ================================== New features: - Directory filesystem ACTION_LOCK_RECORD and ACTION_FREE_RECORD. - Gamepad joystick type for games that support 2nd fire button but can't read it without pullup resistor. (for example Aladdin) - Manual filter configuration fully implemented. - Autoresolution supported (automatically selects lowest used resolution on the fly) - MIDI device names are stored in configuration file. Updates: - Custom chipset undocumented feature compatibility updates. (For example Magic Demo / Diabolics, MoreNewStuffy by PlasmaForce, Kefrens Party Intro by Wiz) - M68K AROS compatible IDE and RTG emulation. - Statefile compatiblity updates. (Initial audio glitches, mouse counters updated correctly, CPU exact mid-instruction state saved, active disk DMA state saved) - New filter defaults, 1x (not FS) and always scale if selected screen/window size is very small or large enough. - Auto resize and center filter modes 1x/2x.. modifiers now adjust window size. - Attempt to load disk image and harddisk paths in state files from current directory, current adf/hardfile path and finally state file directory if original path or file is missing. - SCSI emulation physical drive tray load/eject passthrough. - SCSI emulation CD audio support improved. (for example T-Zero and The Shadow of the Third Moon) - Clipboard sharing disable option in GUI. 2.3.0 bugs fixed: - Audio pitch errors if audio period rate was near minimum audio DMA limit. - Very heavy CPU usage if program continuously plays really short audio samples. - ROM scanner again detects *.rom files in root directory. - Sample ripper works again. Bugs fixed: - Directory filesystem was slow on most modern multicore systems. - CDTV CDA playback didn't work if play ending track was set to last track. (Prehistorik CDTV) - 2352 byte sector plain ISO images didn't mount correctly. - Some drives had problems reading Mode 2 Form 1 data tracks. - SPTI+SCSI SCAN didn't detect any non-CD devices (broke in 2.2.1) - Automatic resize filter didn't always work correctly. - Topmost scanline was usually not visible in autoscale modes. - GamePorts parallel port joystick configuration crash fix. - Random RTG color errors when switching to/from fullscreen 8-bit RTG modes. - Archive mounting crashed if something prevented complete unpack (for example non-dos dms image file) - Harddrive state files didn't save correctly if more than one harddrive was configured. - A2065 Z2 board emulation fixes. (Lost interrupts, broadcast packets getting ignored, transmitter dropping big packets.) - A500 power led fade tricks really work now. - HRTMon didn't work in cycle-exact modes. And more...
