Altirra vs Lynx.emu

Altirra is a Windows emulator for 8-bit Atari computers, covering the Atari 400/800, 1200XL, 600/800XL, 130XE, XEGS and 5200. It provides cycle-exact handling of documented hardware and models undocumented behavior, including DMA timing and undocumented 6502 instructions. Supported files include ATR, ATX, ATZ, DCM, XFD, PRO, ARC, BAS, ROM, BIN, A52, CAS and SAP. Reimplemented operating-system, BASIC and handler ROMs are included, while real Atari ROM images can be supplied for compatibility. The emulator models memory and cartridge expansions, PBI devices, modems and 65C02/65C816 accelerators. Disk options include accelerated loading, realistic timing, sounds and drive CPU emulation. Its debugger offers source stepping, breakpoints, watchpoints, history and profiling. Recording, a cheat trainer, disk browsing and text copy/paste are also included. Altirra is free under GPL version 2 for Windows 7 or later.

Lynx.emu is an open-source Atari Lynx emulator based on Mednafen/Handy, with a minimalist interface aimed at low audio and video latency. It supports.lnx files, optionally compressed in ZIP, RAR, or 7Z archives, and offers configurable on-screen controls. Bluetooth and USB gamepads and keyboards are supported when the operating system recognizes them as HID devices; Xbox and PS4 controllers are listed examples. On Android, it can open files from internal storage, SD cards, and USB drives. The app does not include ROMs, so users supply their own. The EmuEX project targets Android, iOS, and Linux, though the listed Lynx.emu platforms are Android and Linux. Android versions require Android OS 2.3 or later; Linux builds require OpenGL 3.3 support on a desktop or a Pandora handheld. The Android app costs $2.99, paid once. The project is GPLv3 licensed, and the Google Play listing reports no data collected or shared with third parties.
