SNES Shin Megami Tensei urges you to kill
What happens when one of today's gaming discs get damaged or dirty? Well...most of the time not much. The game might not start up at all, a cutscene might skip or you'll just get thrown back to your consoles main menu. In that regard, the old cartridge-based games had a little more to offer. Assuming the game didn't crash outright, you'd often witness strange graphical glitches, hear weird Hypnotoad-like sounds and sometimes even experience some game-altering bug, like being able to walk through walls. Well...either that, or the game channels the forces of Satan and urges you to kill.
Such seems to be the case with the original Shin Megami Tensei for the Super Nintendo. A Japanese user has uploaded a video showing a rather strange occurrence: Instead of playing the intro after the Atlus logo disappears, the game displays a weird screen with red text, accompanied by a horrible sound that's kind of reminiscent of a church organ. See for yourself (the screen appears at around the 2min mark):
So, what does the message say? Simply put, it means "Eradicate immediately!" While the game could be simply telling you to delete your save file or something (albeit in a really creepy way) the verb kesu used here could also mean 'to kill'. I'll let you draw your own conclusions.
Keep in mind that this could very well be fake, but if it's not...God help us. Jack Thompson may have been right all along.
