@AlexMurphy
I'm happy to hear that it should work but as I said : RetroArch reload but the screen now show 1.3.4 - No Core instead of 1.3.4 - MAME 2003 0.78 and I cannot start the game at this point (please note that I have no Core under "Load Core" but all of my games are running fine)
Is the 1.3.4 - No Core error message rings a bell to anybody ? Maybe something I need to configure so the reload will work like adding Core, playing with the ON/ OFF feature for certain parameters ?
@dankcushions and @BuZz , already post this message on the Recalbox Forum but did not receive any answer about the "Load Configuration" function =(
Since it might be a bug in 1.3.4, I will stop harassing you =)
Thanks for everything !
