Here's your Sonic fun fact of the day: Did you realize that Sonic R, if you say it fast, sounds like "Sonic Car"? This is extremely ironic considering most of the characters in the game aren't driving cars! Tune in tomorrow for another Sonic fun fact.
I knew about the level select and debug codes for Sonic 1, 2 and 3 but what I didn't know was that Sonic 3 and Knuckles has a debug and level select too.
I just learned about it while watching Son of a Glitch.
