Hey all. 
 
	Question regarding adding a custom emulator and/or core. I'm attempting to play DOOM and DOOM II through the prBoom core via. RetroArch. There's no option for the core on LaunchBox and when trying to add a custom rom path, I receive the follow message:
 
	Android content activity not found exception: unable to find explicit activity class {com.retroarch.aarch64/prboom_libretro_android.so}; have you declared this in activity in the you AndroidManifest.xml
 
	^ am I to change some text in the above XML file? If so, what part and to what?
 
	The current custom rom path is as followed:
 
	Custom Emulator Package Name: com.retroarch.aarch64
 
	Custom Emulator Activity Name: prboom_libretro_android.so
 
	Custom Emulator ROM Path Key: /storage/DED6-605F/01_SYSTEMS/DOS/Games/DOOM II (1994)/DOOMII/DOOM2.WAD
 
	The game runs through RetroArch fine. I am just stumped to have it run through LaunchBox via the prBoom core.
 
	TIA 🫶
