I have written a longer form post about some of the limitation of the Game Boy with accompanying examples. I had some issues writing longer content for Work Life so I won't really bother with that again.

You can check out the post here (there should not be a paywall): https://jeffzzq.medium.com/some-limitations-of-the-game-boy-67d94a8afb8a

And take a look at the code here: https://github.com/jgensler8/gbdk_bad_examples

What I cover:

• animation with background tiles
• sprite limits
• window flickering
• rom overwriting
