A7800 vs Lynx.emu

A7800 is a free, open-source Atari 7800 emulator and a fork of the MAME Atari 7800 driver. It runs on Android, Linux, macOS, and Windows; version 5.2 lists 64-bit x64 builds for Linux, macOS, and Windows. The emulator supports Proline and VCS joysticks, lightguns, paddles, driving controllers, keypads, Trak-Balls, Amiga mice, and ST mice. Its listed technical work includes improved MARIA DMA timing with accurate DMA-hole penalties, a RIOT emulation fix, POKEY sound changes, and SALLY and MARIA performance adjustments. Users can choose palettes and enhanced screen options. BIOS files are optional and not required. A7800 keeps MAME compatibility and syntax, allowing reuse of MAME configuration files and front ends. Developer targets can display DMA usage per scanline. The repository is offered under GNU GPL version 2 or later, and the license provides no warranty. The project labels v5.2 as its latest release, including corrections to the POKEY poly9 sequence and initial state.

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.
