When you complete the game at a difficulty level (or above), an extra item appears in the option menu. It should be quite easy with all the continues, if you give yourself four lives per credit.

You can access all extra options, plus a training mode (great for practicing for high scores) with the following command. Place the cursor over "Option" in the start menu, then press and hold X, Y, and Z. Now press and hold A, B, and C. (I find it easier to enter the command by holding X, Y, and Z, press and hold A or C, then press and hold the two other buttons half a second later.

physical data of the seals of the different elements.
Special thanks to Mr. Noritama, who maintains an excellent Cotton 2 homepage. Some of the information here has been completed with information therefrom. Also thanks to Mr. MIWA Hideaki for providing some information, and for introducing me to Mr. Noritama's page.
