this is cool

but iirc gameboy cartridges have their own internal batteries which interact with how save files work (in normal games) - and to even replace them you have to solder stuff etc

i wonder if that means this is just a neat toy but not a great cold storage wallet

Looks very cool but the creator is not answering the question “how do I actually sign transactions with it”?

Since it has no camera and no keyboard it is not clear at all how to transfer a transaction into it in order to sign it.
