The Supercard products have been around for quite some time. The Supercard line of products and the M3 line have always been at battle with each other, both sharing their own pros and cons. The Supercard, like the M3, is known for great NDS compatability, but unlike the M3 lacks in GBA support. This is not much of an issue, but it is still a reason why M3 products generally cost more than Supercard products.
