Battery concern

[Arcade-Projects]

Greetings

I've just received my MultiMVS cart and while I was looking through the instructions, I noticed that it mentioned something about the battery. While my current battery is dead, is it really necessary to have the battery?
I am planning to replace it but the battery holder I ordered hasn't arrived yet and I'm wondering if I can still use the cart 'till then. From what I've gathered, only problem I'll encounter is that it won't be able to save some configs but I can live with it (for now).
