Thank you for your quick response, on this subject, after watching a ETA on youtube, he changed the platform to PI3 not sure of the constant name, as I'm on my PC writing this.
I thought there may be ways around it, but after looking at the forums a bit, I see it looks like I newish architecture for the PI4 over the previous models, pitty I like RetroPie, tried DietPi, and got lost, and just started eating :).
Anyways if it's not possible than thank you
