i see that EZIV and Supercard still kind of stick out of the GBA slot, i wonder what about the other 2 (m3 and G6), so which one of those 4 cards fit best?
The idea that these cards don't fit flush is nonsense. The review of the SuperCard Lite said that it was not COMPLETELY flush. When I got mine, it was no issue at all. The stock dust cover doesn't fit COMPLETELY flush if we get TOO critical!
The build quality of the SC lite varies; mine sticks out like less than a millimeter whereas it's pretty much flush on another. If it really peeves you off that much, you could sand down a little off the bottom of the cart.
