Hi, I just assembled the Picade v2 with a Raspberry PI 4 & 32gb NOOBS sd card. It looks really cute and gorgeous, but the pb is the 10’ screen shows nothing. I tried powering the screen with its own USB charger, only to see “No HDMI signal”. I know I should edit boot/config.txt to set hdmi_force_hotplug=1 (I wonder why this isn’t the default value btw), but how can I do this when my only Linux-like OS is the Picade itself? At no moment there a prompt which would allow a sudo nano boot/config.txt. I pluged the SD-card on my Windows 7 PC, but it only shows some files, no “boot” folder.
Another (maybe related) problem: the Picade switch doesn’t light up. I directly pushed the PI switch and witnessed some LED activity so figured it worked anyway, but the Picade button has no effect. I triple checked the instructions though.
Thanks for any help/suggestion.
