I would solder it. The tape will degrade over time, and it's not very secure. 

That was kind of my assumption

But I don't know the first dang old thing about soldering

I don't know a thing about game carts, perhaps they are difficult to solder... but soldering is pretty easy as long as you have the tools (and a relatively steady hand), just practice on a few things beforehand as solder is cheap.
