@buzz Thanks for your answer and your update : https://github.com/RetroPie/RetroPie-Setup/pull/2126
It will help users :)
I will backup my SD to try it.
But to understand fine, will you update all the SYSTEM from BIN ?
If i have some emulators or ES from SOURCE, will they be replace from BIN ? (After i must UPDATE them from SOURCE again)
Because you don't use RELEASE VERSION in RETROPIE-SETUP to update or not a PACKAGE. We can't know if we have the last one, or not ... and i think you can't know it too and you must force update to be sure?
