They both arrived a few days ago, I've tested a few DS backups and they pretty much all run perfect. GBA backups however seem a bit slow, I've been playing a little bit of Pokemon Fire Red.. I'm not sure if its either usual like that or due to "slowdown" but it seems to be quite slow walking..

The software (which I downloaded from the the Supercard website) Is very easy to use, just add a file and it exports it for use with the supercard. It also seems there are regular updates to the software and firmware of the supercard which is always a good sign.

Besides that, I would 100% recommend this to anyone with a DS Lite
