For my own use, and for anyone who cares, I have decided to upload all my cards that were previously unable to be played there to the site. I have all the Archetypes up there now, but the single cards are going to take a while. As such, I am doing them in reverse, as the older cards may need fixing up and some may not even work since I didn't have the full grasp of the new rules at that time. There are links to all the cards in the spoiler below.
In case you didn't know that Duel Portal now has a beta that allows you to play using Link Monsters and the new Extra Monster Zone, check them out with this link:

EDIT: I have now finished uploading all the cards! This took a while, so I hope at least some of you will find use of them. Additionally, I have noticed that the links here don't show the full name, at least for me, so in case that happens to you, you can also see them with this link:
