#1 I already unistall and reinstall the latest version of retroarch, the problem still there. I noticed that when retroarch is on the background, when you click on games in launchbox , it will bring you to Retroarch menu. However if Retroarch isn't active, the click will sometime A) produce black screen or B) retroarch force close. 
 
	For other emulator that i try, Mupen64+ AE free / Snes 9X  - click only bring to the emulator menu. While DraStic, error did pop up saying that error happen while extracting the rom. I have manually tried to open the rom zip with the emulator app, it work just fine.
 
	#2, I don't see any image files when i exporting the snes rom. I have done it couple of time. The file its produce is the game rom and database.
