There are many big names in the Android NDS emulator category, but one that is often missed is the generically named “NDS Emulator for Android.” This emulator sets itself apart from the competition both by being a totally free development, and by running on all Android devices as long as they are version 6 or higher. Features include saving anytime, loading from a previous save file, using cheats, and screen editing so you can customize the display for your android device. One big development this emulator achieved that not many other free emulators have, is the ability to use third party controllers.
Connecting and controlling using your own devices only takes a few seconds, as they have a plug-and-play solution. This emulator is completely free, with no extra charges or features hidden behind a paywall. “NDS Emulator for Android” is in active development, with new features and bug fixes being introduced on a monthly basis. Since this is a free emulator, you can get the exact same features by downloading it from a third party APK website as you would from getting it from Google Play, which gives it an advantage in terms of portability. This is an underrated emulator that I think is often overlooked due to its generic name – a search for its name reveals many other emulators, so make sure you select the correct one!
