What DS Anywhere is

DS Anywhere is a free, open-source web emulator for Nintendo DS games. To run a game, users select an .nds ROM file or drag and drop it onto the site. The project says ROM files remain on the user’s computer rather than being uploaded. BIOS files can be added in Settings to perform a firmware boot and reach the Nintendo DS main menu. The settings include Controls, Personalization, Controller Input, Firmware, and Save Data. DS Anywhere uses a fork of melonDS compiled to WebAssembly, alongside a TypeScript bridge and a Preact/Vite frontend. Its maker describes it as a work in progress, with some features unstable or incomplete, and warns that unintended behavior or data loss may occur. Browser storage can evict save files, and saving a backup or loading a previous save is not implemented. Controller input is supported, but changing controller bindings in the interface is a future goal. Cheat codes and multiplayer are also planned rather than available features; reliable multiplayer may be difficult because of latency requirements. The maker says to use only legally acquired ROM and BIOS files. The project is personal, active development should not be expected, and code contributions and pull requests are welcome.

Who it suits

DS Anywhere suits people who want to run legally acquired Nintendo DS ROMs in a browser and are comfortable with a work-in-progress emulator. It may appeal to users who want to contribute code, but is a poor fit for anyone who needs dependable save backups, in-interface controller remapping, cheats, or multiplayer.
