I discovered yet another bug, this time relating to the saving. I worked for an hour or so in vain when it hit me: I looked in the compile batch file and realized I didn't update the c file I wanted to use. It was compiling using the old c file I hadn't been changing. So I changed it. If there is no save file, I figured "why display 'continue' when you can't?" So when you open the file in an emulator without a .sav file, you'll now get this:

It still saves though if you open the new game and don't do anything, so you'll get 'continue' if you power off the game without moving Frank. I could change that, but I doubt this game will ever get a proper release, so I won't. So therefore, I will put the finished ROM (as well as any future fixes) on the website.

I also switched emulators from bgb to Emulicious. Not only does it save screenshots in .png instead of .bmp, it also has an easier-to-read memory viewer.
