Since 3DS emulation likely won't run smoothly (or at all), you'll have much better luck with these consoles on KitKat:
If your physical Android 4.4.2 hardware cannot handle the heavy lifting of local emulation, your best alternative is network-based streaming. By installing a remote desktop client compatible with Android 4.4.2 (like older versions of Moonlight or PC-to-Android streaming apps), you can run a fully updated 3DS emulator on a modern home PC and stream the gameplay directly to your phone.
If you still want to try, you’d need to look for from 2018–2020. These do not exist in trusted repositories because:
: Devices running 4.4.2 are usually 32-bit with very limited RAM (often 1GB or 2GB). 3DS emulation generally requires a 64-bit processor and a minimum of 4GB of RAM for playable speeds.
Tap seven times until a message says "You are now a developer." Go back to Settings and open Developer Options .
Conclusion Emulating the Nintendo 3DS on devices running Android 4.4.2 is generally impractical: hardware and OS limitations mean few (if any) modern, stable emulator builds will run acceptably. For a workable experience, switch to a modern Android device or a desktop PC running current Citra builds, or use original 3DS hardware. If you still want to experiment on an Android 4.4.2 device, seek archived community builds targeted to older Android versions, proceed carefully regarding legality and security, and expect limited compatibility.
