    So I found this tool, a Game Boy Colorizer. I had an idea, to use this to colorize one of my favorite GB games from my childhood - Golf
    However, when I try to load the game ROM into the tool, i get the following error: "Not enough room for color code. must overwrite ROM code, ROM may not function correctly when colorized." The readme FAQ addresses this and says that "GBColorizer requires a certain amount of free space in Bank 0 to implement color code. If it can't find that space it will overwrite existing code which will probably make the colorized ROM not work."

    So this is where my title question comes in. Is there a way to expand Bank 0 to give it enough room for the color code? Or am I SOL on this?

    Bank 0 is a fixed 16KB block. Bank 1..n are an additional 16KB block that can be swapped between them. There's no way to expand Bank 0. You're SOL.
