So I FINALLY got Frank to compile as a 64k game after working hard at it for a couple hours earlier today. What I plan to do is make Frank be at least 256k. So, on par with commercially-released Game Boy games back then. I have Frank's movements in one bank and will have the background data and other stuff in the other banks. I added a new theme for level 1. So what I will do next is add a level intro screen. This is necessary for the password to be shown some time. But not on level 1 since you can just start a new game and it would go there any way.

I should test this on a real Game Boy. I just found my Everdrive, which is good since I doubt I'll be able to get a new one for some time. A lot of work in just a couple of days. And I haven't really added much of anything, just fixed up code and added in a couple of songs.
