Are we allowed to make ports for other consoles, or does it have to be strictly Gameboy?
if you’re publishing your game on consoles then you probably shouldn’t be putting it in a jam lol. the jam is free to participate in and games should not cost any money to play. it’s rare that you can play console games without buying them.
but yeah, go ahead and port your game to consoles if you want to. we won’t stop you. but as far as a jam submission, it’s probably best to keep it to HTML5 or a Windows build if you want anyone to play and rate your game.
maybe i misunderstood your question though. if you’re asking about other Game Boy consoles like GBA or GB Color, then sure you could make versions if you want, but they would probably break the rules of the jam (like more than 4 colors or maybe the resolution), so would not be acceptable submissions.
