@sumwun, i dont think a video would add any information to this question. I have experienced this on my authentic copy before; while already playing, it just randomly turned to the screen OP mentioned with no trigger. Sometimes it also happens on startup. turn on the gameboy and BAM, same screen.
it's ultimately a read issue with the cartridge. It was coded in to prevent people from playing on gameboys instead of GBC. It's meant to be there; it's just being unlawfully triggered, which is a known issue.
mine just stopped doing it as randomly as it started.
OP probably just needs to clean the contacts and not move around while playing.
it would be great if OP could reply so that we can try identifying why, but this post is just as answerable if we explain the read error and list all possible fixes.
