Thanks a lot for this information, this is getting interesting now. We'll keep an eye on this.

I'm sure Nintendo is doing some research about this cart, they already stopped the "usual upgrade process" of the DS2 with the release of the 3DS. If Nintendo could get rid of such a cart like Supercard or Acekard entirely, that would be a great success for them. These kids usually don't buy a new cart once their cart stops working. At least not every year or so. They just do some rage spamming on internet forums and give up piracy in most cases then.
