Well, I had the same problem:
I had already closed my windows before learning of the Wallpaper-Code-Wallpaper-Code loophole. But... I am still able to use the Organ loophole.
Well, I have 5 tabs open in Firefox, each of them is the Pirates game. I use the time necessary to load through the video to type in the codes of another tab. It works like a very efficient machine producing codes of about 3 per minute.
However, I had to keep to the Pirate's Code: my fifth tab was slowing all the others down, so I had to delete him. But the saddest was my very efficient second tab. He was doing great, keeping the tempo going. Then I hit a button and am sent to one of my bookmarks. Numero dos fell behind, so I was forced to leave him behind.
Now, I still have 1, 3, and 4 open and producing codes.
