ANDSemu vs iDroidDS

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.

iDroidDS, also called nds4droid, is a free Nintendo DS emulator for Android smartphones. It uses DeSmuME 0.9.11 as its core and lists save states, cheat support, and screen layouts for Both, Main, Touch, Portrait, and Landscape. The project is open source under the GNU General Public License, welcomes contributions, and says the emulator has no advertisements. Supported processor architectures are armeabi-v7a, arm64-v8a, x86, and x86_64. This version requires Android 5.0 (Lollipop) or newer; the README says devices with more than 512 MB of RAM and that Android version should be able to run it. Performance can vary with device hardware and the game being emulated. The repository warns that it is not the official nds4droid repository and that the project is not stable. Issues can be reported through GitHub tickets, but reports involving devices below Android 5.0 or ROMs that do not operate correctly will be closed. Dropbox save syncing and work on the OpenGL ES 2.0 and 3.0 renderers are listed as planned tasks. The software is provided as-is without warranty.
