Install flatpak and/or distrobox and you have everything you need.

Correct. If I remove the save then the ROM will take me to the tutorial and everything. I hadn't done an md5 check but your first question had me try something else: i removed the save, started a new game on my phone and saved it the first moment I could. Closed retroarch and restarted it on my phone again, and I got the error again, even though the sage was created by that exact retroarch instance. Then i tried the mew save on the deck and it loaded fine. Seems like I just have an issue with retro arch on my other devices but not the save itself.
From the ROM. I've actually not tried a state because I usually don't use them.
This is an interesting point. One of my other devices is my android, so flash, but another is a laptop with an HDD.
Lol, yeah, why are you working on my stream deck but my other devices?
I'm still waiting for an ice blue shell.
Wait, how did you have the physical PCB? 3d Printed?
