DS Anywhere
What it is
DS Anywhere is a free, open-source Nintendo DS emulator that runs in a web browser. Users select or drag an .nds ROM file onto the site, and the project says those files remain on the local computer rather than being uploaded. BIOS files can be added through Settings to perform a firmware boot and reach the Nintendo DS main menu. Settings include Controls, Personalization, Controller Input, Firmware, and Save Data. The project uses a melonDS fork compiled to WebAssembly, with a TypeScript bridge and Preact/Vite frontend. Its browser-based design is described as limiting potential access to a webpage instead of the whole computer. The maker calls DS Anywhere a work in progress with unstable or incomplete features and warns about unintended behavior or lost saves. Browser storage may evict save files, while backup and restore are not implemented. Controller input works, but remapping, cheat codes, and multiplayer remain future goals.
For and against
For
- Runs directly in a web browser
- ROM files stay on the computer
- Supports firmware boot with BIOS files
- Includes controller input
- Free and open source
Against
- Save files may be evicted
- Save backup and restore are unavailable
- Controller remapping is not available
- Cheats and multiplayer are future goals
The verdict
DS Anywhere offers a browser route to Nintendo DS emulation with local ROM handling and firmware options. Its work-in-progress status, storage limitations, and missing remapping, cheats, and multiplayer require caution.
Who it suits
DS Anywhere suits users who want browser-based Nintendo DS emulation with local ROM loading. It is mainly for users willing to accept unfinished features and possible save-data loss.
