Solved Multiboot NOOBS Raspbian + Recalbox beta xmas edition

[caxelair]

Hi guys,
I did post this on the beta thread as well and edit each of them once answers will be found

I had a RPi 3 B+ for xmas. I'd like to try my second xmas present -> this new Recalbox. However I'm still a noob.

My goal is to have a dual boot with Raspbian (for Jeedom) using NOOBS.

I don't know how to convert the img.xz into a the same format as in: os/recalboxOS-rpi3/ from "recalboxOS-4.1.0.zip" (download here https://github.com/recalbox/recalbox-os/releases)
Even when I mount "recalbox.rpi3.18.12.24.Christmas.beta.img", I don't find the same structure.

Any thoughts guys?
Thanks a lot.

Edit: I did manage to install the old version 4.1

Answer to myself or for folks who try to do the same as me:

"It s a beta
It s not avaible for noobs now."

Beta is Not compatible with noobs.
