DS Anywhere vs DSVita

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.

DSVita is a free Nintendo DS emulator for PlayStation Vita, with an experimental Android port and a documented ARM Linux build. The maker says most games run, although some emulation features are incomplete. Two-dimensional rendering is mostly complete, while three-dimensional rendering is mostly implemented; missing effects and games using 3D on both screens can cause slowdowns or stutters. When ARM7 HLE fails, SoundHle or AccurateLle may be more compatible but slower. Release 0.9.4 lists savestates, Action Replay and libretro cheats, touchscreen controls and customizable control profiles. The rear touchpad can map to the DS touchscreen, and the right stick can control it. ROM files must use the .nds extension and be placed in ux0:data/dsvita. Vita installation requires libshacccg.suprx and kubridge.skprx 0.3.1 or later. Automatic frame skipping is always used, with no scanline rendering. The project recommends overclocking the Vita to 500MHz.
