DS Anywhere vs DSperate

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.

DSperate is a free, public-source Nintendo DS and DSi emulator for Linux on AArch64 and ARMhf. Its CPU emulation includes ARM946E-S and ARM7TDMI interpreters, plus ARM-to-AArch64 and ARM-to-ARMv7 recompilers. Graphics include complete 2D engines, a software 3D rasteriser and optional Vulkan GPU rendering. Experimental DSi support covers DSiWare, NAND boot, an SD card folder, microphone, Wi-Fi, PictoChat and Download Play, but the DSi DSP is not emulated and DSi-enhanced cartridges run as DS games in DSi mode. Local multiplayer and Download Play work over a LAN; internet access uses a user-mode TCP/IP stack. It has ten save-state slots and a hidden automatic slot, configurable screen layouts, cheats, and remappable keyboard and controller input with stylus support. Games can run with built-in FreeBIOS and generated firmware; user dumps allow firmware boot and exact timing. It loads .nds files and .zip files containing an .nds, but not zip64, 7z or rar. The project is licensed under GPLv3 and describes its implementation as clean-room work.
