Short version:
Problem: Smart Card has weird saving issues. It appears the battery housing is not fully soldered to the board.

Solution?: I have no access to a soldering iron, could I connect it to the circuit board with hot glue?

Long-ish Version:
So I got a new cart the about 2-3 weeks ago and have finally gotten around to using it (running LSDJ). However, whenever I power on my gameboy it almost always initializes my .sav data. On the occasion that it doesn't initialize I'm still able to back-up the .sav file after playing and when i power on the gameboy again.... WHAM initialized. I think it could be battery related and when I popped the cart open it looks like one of the battery housings connections isn't fully soldered to the board (the tab facig the "open" end of the cart). So what do you think, does this seem like a likely problem?
