I have the GBM + Ez-4 setup that's ... basically ... what ... everyone ... here ... seems to have. I've noticed a hardware problem. Whenever I press firmly on the middle of the back of the system, the Ez-4 blacks out. I figure it's pushing the battery out of position. Is this a common issue, or do I have a badly built Ez-4? I know it's the flashcart because retail cartridges do not have the same problem. ... Also, I was looking at reviews to fix this, and was wondering if it would be useful to get a Supercard Mini SD. Did that hardware better support real-time clock games, or approach saves in a more agreeable fashion? Please note - I'm aware getting a Supercard Mini from a retailer is next to impossible - just wondering whether or not there would be any benefits to having one over an Ez-4.
