http://virtualdub.org/altirra.html Altirra 1.9 Test 19 is released. Altirra is an Atari 8 bit Emulator on the Windows/DOS platform. Altirra emulates several models of the 8-bit Atari computers. This includes the the 800, 800XL, and 130XE versions. It has a lot of options, and compatibility is decent especially given the emulator's early stages. It also supports some copy protected games properly in emulation. Altirra 1.9 Test 19 Changelog: features added Debugger: Multiple memory access breakpoints can now be placed.

Debugger: Added vta, vtc, vtl, and vtr commands to control verifier OS entry point checking. Debugger: Added .dumpsnap command. SoundBoard: Initial support. UI: Added emulator crash dialog. UI: Show FPS option now also shows CPU usage. Input: Added Amiga mouse support. Input: Added CX-85 keypad support. GTIA: NTSC and PAL modes can now have separate palettes. GTIA: Added option for PAL encoding quirks. GTIA: Added PAL high artifacting mode. Disk: Initial version of disk explorer. Serial: Inbound connections are now supported. Serial: Added support for A, L, M, P, Q, S, T, V, X, &C, &D, &F, &G, &P, &T, &V, and &W modem commands. Serial: Added DTR and CRX signal support. Serial: Added IPv6 support. Serial: Added option to force specific connection and DTE communication rates. Cartridge: Two cartridges are now supported for 800 left+right and stacked cartridge configurations. Cartridge: 2K and 4K cartridges are now supported (as mirrored 8K cartridges). bugs fixed UI: Pane dragging is less twitchy and no longer undocks a pane as soon as you click on the caption. UI: Optimized Direct3D9 code to reduce flickering when switching artifacting modes. HLE: Fixed crash when NMI handler is invoked with no NMIs pending. HLE: Added support for XL OS PENTV vector. Simulator: Default kernel mode now prefers ROM images properly again. Simulator: BOOT? and DOSINI are now set at the beginning of EXE/XEX loads to support more WARMSV tricks. Cheats: Enable checkbox on cheats was broken. CPU: Added missing SHA abs,Y ($9F) instruction. CPU: Fixed CMOS BIT #imm ($89) instruction. CPU: Fixed 65C02 $FC instruction. CPU: Back-to-back interrupts are no longer allowed. CPU: Added emulation of BRK/NMI bug. CPU: Added option to emulate masked NMIs (off by default). ANTIC: DMACTL bits 6 and 7 are no longer reflected in .dlhistory output. Debugger: Optimized History pane. Debugger: Avoid re-requesting the same source file when it is not found on disk. Debugger: Improved reliability of source-level stepping. Debugger: Added XL OS entry points to default entry points allowed by verifier. Recorder: Fixed crash on recording errors. Recorder: Fixed incorrect format on video stream when using ZMBV compression. Disk: SIO receive speeds are now validated for more reliable high-speed SIO detection. Disk: VAPI (ATX) images can now be loaded from .zip files. GTIA: NTSC high artifacting mode now respects artifact phase setting. GTIA: Fixed trigger state sometimes being initially wrong when enabling latching. GTIA: Improved accuracy of transitions from mode 8 to mode 9/10. Serial: Telnet emulation now reads out of band data. Serial: Telnet emulation now handles incoming WILL and WONT commands. Serial: Telnet server now attempts to turn off local echo on remote end. Serial: Fixed sporadic missing newlines on modem status messages. Serial: Control line state is now reported in non-concurrent mode. Serial: Ring pattern adjusted to match US standard (2s/4s). Serial: Re-opening the R: device now flushes buffered data. Serial: Closing the R: device deactivates concurrent mode to make subsequent status requests work. Serial: Fixed crash in R: when invoking GET BYTE with an empty input buffer or PUT BYTE with a full output buffer. Serial: Fixed BASIC GET command failing after XIO on R:. Serial: Fixed erroneous CR-to-CRLF conversion on transmit path. Printer: Fixed close command not actually closing IOCB. http://www.virtualdub.org/beta/Altirra-1.9-test19.zip --
