I thought I’d port my homebrew game I made for the Sega Game Gear over to the Virtual Boy, even though it only has 3 shades of red and black. (Anyone like their burgers extra-rare?)
This is the title screen. Works fine on a real VB (tested with a FlashBoy+). http://www.atari2600land.com/vbdev/hamburgers20201022.zip
Will be working on level 1 soon.
That should fit in the prototype window without cutting off any graphics. I would suggest adding 3 more pixels of gray background to the right side, into the black border. Otherwise you might have a small strip of that black border peaking out along the right edge of the screen on the final production units.
