Imagine a six year old getting Sonic One for Christmas, putting it in his Sega Genesis, and seeing this happen. I wonder what that kid would think of the sonic franchise after that.
That happens even on regular hardware it is called error reporting and sonic team could use the error that pops up to find what they needed to fix during development.
this can happen on the real console. it's just that the error name sounds rather nonsensical to a random human that doesn't even know about assembly programming (also i think that the error name means that some instructions cost too much RAM)
A line 1111 emulator, a illegal instruction or a address error is where it detects a error or a game where its not linked together or its too much to handle.
