Strange Game Boy Insert

[GamerSmith548 | 42]

I’m sure you all know about the countless revisions of precautions booklets the Game Boy had, however, I found out recently that there was something similar to it that must have been used before the booklets were used, more specifically a yellow sheet with the code DMG-DOC-USA. Anyone know when this was used? I can’t find any information on it anywhere.

It's an epilepsy warning. I've seen a few of them in the Basic Sets.

This insert was only included in the later pink grid boxes (like the image shared by hst), not the earlier orange / black grid boxes.
