It was indeed House of the Dead that had me excited. Considering the value, I may as well have found a $5.00 copy of Wild Gun. Unfortunately, the Daytona CCE isn't the Netlink edition.
Lunacy was a bit of an odd case. The previous owner had crammed the second disc tray behind the manual tabs. He had somehow done this without damaging the manual as well. Working very meticulously, I was able to remove the manual and eventually the disc tray. I'm not sure what drove the previous owner to do that (or how it was even done), but I can only assume he went looney playing Lunacy.
Thanks for the website reference. It should prove useful for finding Japanese games that I can actually play and understand. Though I think I'll start with something simple like Bubble Symphony. Bubble Bobble Part 2 just doesn't do it for me; I need a new console Bubble Bobble game that I can play cooperatively.
