This page showed up in my Twitter feed today. I thought some people here may find it interesting.http://www.vgmuseum.com/features/warn/
Some of the art made for the incompatibility messages happens to be rather enjoyable.
I wonder why the incompatibilty message for the German version of Monsters Inc (GBC) got inverted when compared to the English version.
I also note similar fonts used in some of the messages; could these be tied together by a common dev? (the one I noticed specifically was the one used by Micromachines V3, Championship Motocross, and other GBC games; as it's also used in the copyright messages of the first Harry Potter game for GBA, which I have a cart of.)
