ppsspp core issues

i have tested ppsspp nightly 
core will goes with black screen (just buggy audio)
i changed the core to  https://github.com/Swordfish90/LemuroidCores/tree/master/lemuroid_core_ppsspp/src/main/jniLibs
in build gradle
and after copy the assts to /data/data/pkg/system/ppsspp
it worked
i want to know is there any way that i can change this path to /data/data/pkg/files/system/ppsspp
???
thanks
