DraStic

i recently got DraStic emulator for my android phone along with a GBA emulator and it seems that DraStic sees the gameboy folders but there's nothing inside them and i was wondering if i could remove them from drastic without removing them from the phone completely for i fear that would erase everything from the GBA emulator (the gba emulator is Jonh GBA)

The only place drastic puts it's files is in the DraStic folder in the root of your SD card. In general, leave the folders in there alone, even if they're empty.

DraStic does not also look for GBA games/saves automatically, although it does have Slot2 save support (for transferring Pokemon and that WarioWare Twisted thing)
