ANDSemu vs DSperate

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.

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.
