Do you have an open source one in mind?
There's a port of melonDS to Android at https://github.com/rafaelvcaetano/melonDS-android. Keep in mind you'll need a CPU capable of running AArch64 instructions and a 64-bit OS if you want dynarec support.
thanks for using Leebra!

I usually recommend using open source software but this is c/piracy, so, you can easily find Drastic unlocked on Mobilsm.
