In their own words
A7800
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.
