When a video arcade game or video slot machine has an error where the screen still works, have an error message that somehow fits the theme of the game while still getting the point across.

The first Wing Commander game did something like this: >Back on the first Wing Commander we were getting an exception from our EMM386 memory manager when we exited the game. We'd clear the screen and a single line would print out, something like "EMM386 Memory manager error. Blah blah blah." >We had to ship ASAP, so I hex edited the error in the memory manager itself to read "Thank you for playing Wing Commander." - Ken Demarest https://www.gamedeveloper.com/design/more-dirty-coding-tricks-from-game-developers
