ANDSemu vs DSVita

ANDSemu is a free, open-source Nintendo DS emulator for Android phones and tablets. It provides a streamlined graphical interface for running Nintendo DS games, with portrait stacked, landscape side-by-side and landscape stacked screen layouts, plus LCD swapping. Save states and cheat support are included. The project describes its code as based on nds4droid and DeSmuME, and also names DSdroid in the repository. ANDSemu is licensed under GPLv3; redistribution, forks and selling a fork require compliance with that licence, including source files and build scripts. The README recommends Google Play installation and gives source compilation as an alternative. However, AppBrain reports that the app was removed from Google Play on January 14, 2013. Its historical listing describes a free download requiring Android 2.3.3 or later. Source builds require ActionBarSherlock, Android Support Libraries and ndk-build for DeSmuME and other native libraries.

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.
