@vukilore Recalbox n'est pas une application mais un OS à part entière. Il n'est pas possible de l'installer sur smartphone, même jailbreacké.

Du coup wiki documentés:

@dagda94 n'hésite pas à passer le sujet en résolu ;)

Well thanks to @paradadf it worked ... I completely forgot about it ... Thank you very much !

Now I have to set everything up ! :D

Never mind it was an issue with the hdmi cable being dirty oops

Hello
No chance.

Thank you, this was exactly the problem. I forgot everything must be on FAT32 to work on the Pi. I used the Disk utility on my Mac to format and now everything works fine.

Mine was detected by windows as 64gb too, and i can used it, but when recalbox tried to format it on ext, there was on error. These fake SD are detected as 64gb but only 7 or 8 gb are available.
