WatermelonDS review
A free Android emulator with broad DS and DSi features, but no local multiplayer.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WatermelonDS is an open-source Android emulator for Nintendo DS and DSi software. It is aimed at Android users who want DS and DSi features on handheld devices or hardware connected to external displays. The feature set covers core emulation, DSiWare library integration, save states, cheat support and RetroAchievements with offline play. Its GPL-3.0 license also makes its open-source model a central part of the product’s profile.
Display and rendering options are a major focus. WatermelonDS supports software, OpenGL, Vulkan and compute renderers, along with internal resolution scaling and RetroArch shader presets. Per-ROM screen layouts, screen rotation, an editor and external-display layouts provide control over how the two screens are arranged. These options make it a fit for Android setups where screen placement, rendering method or a larger external display matters. The product is less suitable for users who need local multiplayer or DSi SD-card support.
The published feature set is available through a free, open-source Android project rather than separate paid tiers. Buyers should choose WatermelonDS if they want DS and DSi emulation, customizable layouts, DSiWare integration, cheats, save states and RetroAchievements without a paid plan. Users who require local multiplayer, DSi SD-card support or a platform beyond Android should consider an alternative that covers those requirements. For Android-focused single-device play, its breadth of rendering and layout controls gives it a clear practical focus.
