Ah, thank you very much! I don't know how I missed that option scrolling through settings.

@bananapi761 the -dev package is always a source install, otherwise the package would not the latest version.

@danield420 well the black screen could be a bad rom or possibly a missing bios file. Sure there are other factors for the balck screen i'm still learning myself. This RetroPie Github page has helped me so much https://github.com/RetroPie/RetroPie-Setup/wiki/Supported-Systems . Or make another topic and i'm sure someone can help you solve the problem if you didn't already on your own.

@BuZz You were not far from the truth, for some reason I had it in mind that fbalpha was also distributed as a standalone emulator, but it's just pifba (and the older lr-fbalpha-2012).

@herb_fargus I was just thinking out of the box, cause he said that his gamelist.xml is a nightmare. If he gets the log way, he will need to play all the games to fill the txt. This could take a lot of time with his 10k gamelist.

This sounds like Something you should post in the Help and Support section. People there might be able to help you. I have no idea as to what could be causing this, sorry I couldn't be of more help.
