I recently purchased a Supercard DSTwo for my 3ds and when I go to boot up any ds rom the touchscreen doesn't register. it's not a problem with the touchscreen itself because I'm able to play 3ds games without any problems, but whenever I try to play super mario 64 ds or pokemon black, or any ds rom the touchscreen doesn't work. I had the same problem when I went to use my DS Lite and both the EOS and Firmware are completely up to date. I was wondering if anyone else has had this problem, is there any fix, or do I have a faulty supercard.
