Altirra 3.90 Test 26

Features

• Emulates the Atari 400/800, 1200XL, 600/800XL, 130XE, XEGS, and 5200 systems.
• Full, cycle-exact emulation of all documented hardware features.
• Best-in-class emulation accuracy of undocumented hardware behavior, including undocumented 6502 instructions, precise DMA timing, mid-screen register changes, hardware bugs, and cycle-precise timer IRQs.
• Support for most popular 8-bit image file formats: ATR, ATX, ATZ, DCM, XFD, PRO, ARC, BAS, ROM, BIN, A52, CAS, SAP.
• Contains reimplemented versions of OS, BASIC, and handler ROMs to run 8-bit software with high compatibility without needing Atari ROMs.
• Emulation of over three decades of hardware expansions, including memory expansions, cartridge expansions, Parallel Bus Interface (PBI) devices, modems, and 65C02/65C816 accelerators.
• Accurate emulation of multiple disk drive types with options for accelerated disk loads, realistic disk timing, and drive sounds.
• Flexible display with Direct3D/OpenGL acceleration, aspect ratio options, easy resizing, and artifacting support.
• Audio and video recording, cheat trainer, DOS disk explorer with drag-and-drop, and text mode copy/paste.
• Powerful debugger with label decoding, source-level stepping, conditional breakpoints/tracepoints, watchpoints, execution history with loop/call/interrupt folding, and profiling.
• Native Windows UI with theme support, per-monitor high DPI support, file associations, and DirectInput/XInput controllers.
• Both 32-bit (x86) and 64-bit (x64) versions available.

• Secondary POKEY channels can now be muted.
• Fixed a bug in the co6502 trace cache that caused some bogus execution histories for 810 full drive emulators.
• Fixed 810 full drives improperly taking too long when attempting to boot with no disk in the drive, causing boot commands to time out. This started happening due to the fixes to RIOT emulation; the additional bug here was not emulating the FD1771's behavior of failing after only two revolutions instead of five like newer FDCs.
