Classic Concentration (NES)
This game has unused graphics.
The NES Classic Concentration is based on the game show of the same name, which at this point was close to the end of its run (first-run episodes ended in September 1991, with repeats airing through the end of 1993).
An unused Softie logo is present in the ROM. It was intended to be displayed on the title screen, and you can see this using Game Genie code GEKNLKOP.
However, Softie's credit is smaller than Nintendo's, resulting in them overlapping.
Intended for when the computer-controlled player wins a game. Still better than making up dumb excuses.
THAT WAS JUST A PRACTICE MATCH! TRY ANOTHER GAME!
YOU OUGHT TO BE WARMED UP BY NOW. TRY ANOTHER GAME!
I WAS JUST LUCKY THAT TIME. TRY ANOTHER GAME!
