@windg Yeah, sorry for my rudeness. I dropped the thing and I feel better now :)
I'm just a little bit annoyed that retropie is the only versatile tool there is to do as much as I want (which is configure everything) but that its soooooo unorganized (it reminds me of Blender ah ah, wonderfull tool too but too messy for my taste)
I stopped trying to configure retropie, I'm tired to have to search in the doc for every little thing because nothing make sense. Even the folder tree is a nightmare -_-.
Well sorry again, I won't polute this forum any longer. Cheers.
