That's interesting! The version that Mr. Do sent me is the green version (with Japanese text for the buttons). I agree that this game should to be split up in two versions (parent/clone).
Are you sure? I could have sworn that the one I bid on was pictured purple, because I tried to bid on a green one later and lost it. But at the same time, I never saw it; it went straight from a friend in Japan, to Sean, then to you. If it is the Green one, then that is great, as the purple is a bit easier to track down.
Note that there is also an early version of Helmet (Silver), though you can only tell by taking the cover off. Bugfixed version is CN-17 (which you have of mine); original version is CN-07.
Below is the "cheat" that could be done on the original CN-07 version:
--When in clock mode, push and hold the TIME button. The Helmet character will stop moving and will eventually get hit by a falling object and fall over. After the character falls over let go of the TIME button.
-- Immediately after letting go of the TIME button, push the GAME A (or GAME B) button and the TIME button at the same time.
-- Next, hold down the RIGHT button and then let go of the GAME A (or GAME B) button and the TIME button.
-- When the game starts you will have two Helmet characters playing at the same time, and both characters can accumulate points.
In regards to earlier post about the Melody Rom for Mario the Juggler... do what you gotta do to make what's preserved more accurate. =D
