What DSP Emulator is

DSP Emulator is a free emulator project for arcade games and home computers, with public source code and downloadable binaries in its repository. It supports Windows, Linux, and macOS. Listed computer systems include ZX Spectrum, Amstrad CPC, Commodore 64, Oric Atmos, and MSX 1, while arcade drivers cover hardware and games such as Galaxian, CPS1, Sega System 16B, HangOn, Lastduel, and Rastan. The changelog describes automatic tape loading for several computers, including TZX, TSX, CAS, and WAV formats on MSX 1. Input handling combines keyboard, joystick, and arcade controls, with joystick button remapping. Users can type a title in the game-selection window, and driver information can expose ROM and sample files for export. The project also includes snapshots, DIP-switch settings, a compilation document, and a short user guide. Version 0.24WIP3 is listed as a work-in-progress release dated 11/11/25.
