I have been working on Frank the Fruit Fly, trying ever so hard to not make the screen blink when the toilet's message disappeared. I had tried printn and print but the compiler didn't like those. Suddenly, while going through sample code, I stumbled upon something: getxy and setchar. This was great. I could put letters wherever I wanted on the screen. Too bad I have to type them one at a time. But still, I found something that worked. To make the letters in the message disappear, I could set them as spaces. And then turn them on again at will. With no screen blinking.

I wonder why the BGB emulator decided to save screenshots as .bmp files. They're such large sizes for a small image. PNGs do the trick better, so I have to convert them.
