Read this if you want to use Retroarch 32-bit
Since the play store changed paths to "retroarch.com.ra32" you can no longer use 32 bits in dig.
If you want to use it, you have to download the 32 bits apk and edit it in APK Studio, edit the XML file from the root directory and change the line retroarch.com.ra32 to retroarch.com and then install it
You will have to uninstall retroarch first
And then dig will pinpoint to the 32 bit app, and if you want to use 64 bit you'll have to install retroarch plus separately.
FYI
