#1 was a problem in my LAN that I solved. Afterwards max2play was accessible until
#2 the Raspbian went into maintenace mode and could not be accessed by the webinterface anymore after I had set a fixed mount point.
#3 I downloaded the RA3 imagine and after downloading the additional plugins and a lot of reboots it seems to work now except for the WLAN which I’ll look into tomorrow.
I guess most people now take the Raspi3 so it might be a good idea to offer an image with Touchscreen for this one
