Man, I got a fake game.
You know how it is with collectors, you get a new game, you might not get to it for quite a while. That's what happened here.
I got Super Mario Bros. Deluxe for GBC. I tested enough to see it powered on, and didn't pay much attention.
I started it playing and it's a cartridge with a ROM dump on it. I know because the start-up screen has a little logo of the guy that made ROM, Nick Mueller.
Here it is I don't know how long since I got it, even if I did, the trade site I used to get it is gone (99Gamers).
That sucks.
