@zing Thanks for your help. I'll reinstall those in the for the new version.

@zing Hi! My old version was 18.07.13 It was stuck to this version and unable to update it so that's why I wanted to start from scratch. In the roms folder of the old version I have fba and fba_libretro only and same things in than the new SDcard and in those there a few file and a gamelist but don't have a lot of game like the others console. But when I enter old SDcard in the Pie3, I can play the games but with the new SD I don't see any games... Thanks

Hi, I downloaded the new version of Recalbox on a new microSD card and transfer all the content of the old roms directory on the new card and put the new SD in my raspberry pi 3. And now in the Mame section, I don't have any of the 1000 something that I've before on the old SD card but I see all of the other roms from other console... I need help to figure what I miss... Thanks!
