Altirra 1.9 Test 5 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.

test 4/5 test 3 Bounty Bob and Nuclear Nick fixed (Breaker: cartridge game "Bounty Bob Strikes Back!. rom" — refuses to run.) test 2 BASIC option should be working again for 800 mode, but you need the hardware mode set to 800 *AND* the OS set to OS-B. It wasn't actually the EXE break option that was the issue, but an extra event I had added to the simulator. Should be fixed now (Issue by MacLane: exe files are no longer listed unless you do show all supported every time). Debbuger hidden dialog (Issue by Breaker) - I added the crash dialog as something a bit more friendly than just dumping people into the debugger. It doesn't come up if you are already in the debugger, and otherwise pressing Pause will drop it. Esc/Close also works since I bound Pause to the cancel option. Some of the options are grayed not because they aren't implemented, but because they don't apply -- for example, you don't get the option to disable BASIC if it is already disabled. I fixed the mapping problem on the MaxFlash carts. test 1 Debugger:Multiple memory access breakpoints can now be placed. Debugger:Added option to break on run address of loaded executable. Debugger:Conditional breakpoints (bx) are now supported. Debugger:Commands can now be run when a breakpoint fires. Debugger:Added ? (evaluate) and .printf commands.

SoundBoard: Initial support. UI:Added emulator crash dialog. bugs fixed UI:Pane dragging is less twitchy and no longer undocks a pane as soon as you click on the caption. 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. Cheats:Enable checkbox on cheats was broken. CPU:Fixed CMOS BIT #imm ($89) instruction. CPU:Fixed 65C02 $FC instruction. 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.
