I'm searching to play a game that has an OBB file for its data. I have the file and the apk, but ARC welder doesn't seem to have a way to select the OBB file directory. Is there another way to allow the app access to the folder.
You can do this, you just have to launch the app once, let it crash, and then place the obb file in the "Android/obb" subfolder of the unpacked extension.
See here for more info.
