I had to make several changes to the marathon schedule. Here are three of them.
Book of Legends won't record without graphical issues. The game is just too old. I'd have to record it on my Windows 7 computer, which wouldn't be the worst thing ever, but I'm too lazy to set that up. So I replaced it with Nancy Drew: The Model Mysteries for the DS.
Mystery Case Files: 13th Skull doesn't work with Fraps. Again, I'd have to record on my older computer. I tried, but the first half hour of the game ended up being twenty minutes of hidden objects challenge FAILURE. So I decided to replace this run with NightFall: An Edgar Allen Poe Mystery. That's a freemium game which I played for about an hour and a half, before running into the "pay us money or wait several hours" wall.
[Edit: I figured out how to record MCF 13th Skull, with one of those Twitch programs. We'll see if the quality is any good.]
There were graphical issues with Drawn: Trail of Shadows. The game just outright crashes for me, after you draw the first picture. So my walkthrough ended up being 15 minutes long. Instead of replacing it with something else, I decided to keep it as is. After all, three people requested it. Also, I'm lazy.
