Where can I buy physical copies of homebrew games for the Game Boy? I've been working on GoSub and it's making me want to try out some other Game Boy homebrew games.

I made a couple of changes to the border. I think it looks better.

I also made the sub fall apart when it crashes. It adds a touch of realism instead of just stopping when it crashes. But I think of the poor crew drowning when I hit something when I test it now. Also, would anyone like to publish it when it's done? The game is 64k, so it's not just a basic small 32k game.
