There are two versions of Mega Man 2: Version 1.0 and Version 1.1. Version 1.0 features Crashman in the stage selection screen but erroneously refers to Clashman in the instruction booklet. There is a flaw in Japanese-English translations where Japan has no equivalent for "R" or "V", forcing them to occasionally use "L" or "B" as replacements. This is why in Version 1.1 Crashman, who wears a crash helmet and whose stage consists of crash stunt-oriented robots, is referred to as Clashman. This mistake is also made in Mega Man 2 for the Game Boy.
