In their own words
NESER
NESER is a free Nintendo emulation systems engine written in Rust, with desktop and browser frontends. It supports NES and Famicom variants, Game Boy and Game Boy Color, Game Boy Advance, and Super Nintendo systems. Shared platform code covers audio, video, input, save states, configuration, ROM browsing, and debugging. The native frontend supports keyboard and gamepad input, with NES-specific devices including the Zapper, SNES Mouse, Arkanoid paddle, Power Pad, and Four Score. NES users can choose shader presets such as CRT, NTSC, smooth, PAL, or none. The browser frontend accepts ROM files for the supported systems. For scripting and CI, headless mode runs a ROM and writes a PNG frame; the same ROM and frame count produce byte-identical captures across runs and builds. NES development tools include a debugger, CPU trace, breakpoints, and deterministic autorun recording and playback. A built-in open-source GBA BIOS means no external BIOS file is required. NESER is MIT-licensed and can be installed with cargo install neser or obtained as a prebuilt release.
