I actually paid $20 for everything! It was a great deal. I'm not sure if you were joking about buying the game(s) but at this time, I'm not interested. The good news for everyone is that I am interested in getting the cart dumped so everyone can play it. The problem is I'm very paranoid and want to do it locally. I'm uploading the pictures now, but I had to send them separately, so check back within a few minutes. I do have an old video I made on YouTube about the Bart's Nightmare prototype. As far as I know, there's not a whole lot different except for a screen you get that wasn't in the final release.
Edit: Okay, I'm not really sure how to upload photos on here, so instead, I'll post a YouTube link to the video:
