if it was sold as a piece of hardware that happened to include a game, then it would be hardware in the database (examples being the many console bundles). if it was a game that happened to include hardware, then it should be software in the database (examples being special edition games that came with a controller or accessory, like zelda skyward sword with the gold wiimote).
looking up magic swap, do you mean this?
https://en.wikipedia.org/wiki/Swap_Magicif it's that, i agree that it should be software and don't understand why it would be hardware...the only reason i could imagine it not being accepted right away would be because it's related to piracy? the site doesn't encourage piracy, so that could be why it hasn't been accepted yet, but if that's the case you should receive a PM from staff explaining why it wasn't accepted.
