DS Anywhere vs iDroidDS

DS Anywhere is a free, open-source Nintendo DS emulator that runs in a web browser. To launch software, select or drag an .nds ROM file onto the site; the maker says those files remain on your computer rather than being uploaded. BIOS files can be added in Settings for a firmware boot into the Nintendo DS main menu. Available settings cover 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 maker describes the project as a work in progress with unstable or incomplete features and warns about unintended behavior or lost saved data. Browser storage may evict saves, and backup or restoration is not implemented. Controller input works, but changing bindings in the interface is still planned. Cheat codes and multiplayer are future goals; reliable multiplayer may be affected by latency.

iDroidDS, also called nds4droid, is a free Nintendo DS emulator for Android smartphones. It uses DeSmuME 0.9.11 as its core and lists save states, cheat support, and screen layouts for Both, Main, Touch, Portrait, and Landscape. The project is open source under the GNU General Public License, welcomes contributions, and says the emulator has no advertisements. Supported processor architectures are armeabi-v7a, arm64-v8a, x86, and x86_64. This version requires Android 5.0 (Lollipop) or newer; the README says devices with more than 512 MB of RAM and that Android version should be able to run it. Performance can vary with device hardware and the game being emulated. The repository warns that it is not the official nds4droid repository and that the project is not stable. Issues can be reported through GitHub tickets, but reports involving devices below Android 5.0 or ROMs that do not operate correctly will be closed. Dropbox save syncing and work on the OpenGL ES 2.0 and 3.0 renderers are listed as planned tasks. The software is provided as-is without warranty.
