@the-grand-puba Firstly, if you should post in the international area, because you are posting in English, the "Français" area is only posted in French.
Second, I could not figure out what your problems were, apparently you did not even try to configure the control, nor did you have a lot of notion about the recalbox, since you're "questioning" the fact that the system "only has 6-7 emulators."
Since I can not understand exactly what your problems are (consider that I do not speak English very well), I do not know if I can help you, but it seems that you need to read the manual to understand better:

About joystick setup, it is in the manual, and if it is impossible to configure the controls with only the controls, you will need a keyboard to access the joystick setup menu.
