Apparently, as cool as this place is, it works just like Deviant Art, meaning it regenerates every PNG we upload, and thus destroys the game card's original metatag programming--embedded within the PNG.
If you want an "actual" card, we also post at Kenzato, Pixiv, F95Zone, and Illusion Booru. We also have a monthly sharing of all our cards in a handy pack every 25th of a month. If you do not wish to hunt down all or work, and have 1 US dollar, you can just wait until every 25th of the month. :)
