I tried transferring a sd card of 9.2.2 onto a 256GB NVME via the sd copier app in RPiOS and a USB sd card reader. It boots but has issues. It's in "IN MEMORY!" mode saying 0B/128MB(0%) under System Settings. No changes are saved and the initial install slide show plays every start up. Is there a way to install Recalbox onto a bootable NVME yet?

I figured it out. I couldn't even get the latest RPiOS image to connect to wifi. I had to Disable "802.11ax / WiFi 6 mode" under Advanced settings -> Wireless -> Band 2.4GHz on my Asus router.

I have 2 Zero 2W running Recalbox 9.2.2. Both can not connect to 2 different WiFi routers in the US. I enter the Network Name and Wi-fi Password but the IP Address ends up being a long hex number like fe80::7f7f:4bea:f71c:29bb (ipv6?). I've exit ES to a terminal Alt-F2, Alt-F4. I've set the country code to US in /recalbox/share/system/recalbox.conf. I can scan for wifi via the menu and it does see the networks but just can't seem to connect. I tried populating a wpa_supplicant.conf file in /boot and that also did not work.

Anything else I should try?
