DSVita vs Pilas-melonDS

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.

Pilas-melonDS is a free HTML5 and WebAssembly browser frontend for the melonDS Nintendo DS emulator. It opens.nds,.dsi, and.srl files, runs in DS mode by default, and offers experimental DSi mode. Controls include keyboard, Gamepad API, touch, and DS touchscreen input. Users can choose Canvas 2D, WebGL 2, or WebGPU rendering, with audio through WebAudio. Cartridge saves and browser save states use IndexedDB, with as many as six save-state slots per ROM. The frontend can install DSiWare.cia files into DSi NAND or virtual SD storage. Camera and microphone input for DSi require browser media permission and a localhost or HTTPS origin. Browser internet mode provides a compatibility shim for DHCP, DNS, ARP, and basic TCP/HTTP, but it cannot provide arbitrary raw UDP/TCP internet or decrypt HTTPS traffic within the browser sandbox. DSi menu boot requires legally dumped BIOS files and a writable NAND dump; normal DS direct boot can use the built-in FreeBIOS fallback. The project is licensed under MPL-2.0.
