The NES version of Gradius introduced the famous "Konami Code": Up, Up, Down, Down, Left, Right, Left, Right, B, A. The world would never be the same.

PRG CRC Test

Man United Nil

Hold A + B, then power on the game to access this test. "KONAMI ONE" will be displayed if the PRG CRC matches the internal value, otherwise "KONAMI TEN" will be displayed.

The same method is used with the CHR data integrity status to show "GRADIUS ONE" or "GRADIUS TEN". The European version fails the CHR check, despite using the same CHR ROM as the USA version.

Similar tests appear in other Konami NES games such as Ganbare Goemon!, The Goonies II, and King Kong 2.

The Japanese version's title screen displays the high score and uses the old Konami logo that was in use from 1981-1986. The European title screen introduces a graphical error on the right-hand side of the Gradius logo: a diagonal tile was mistakenly used instead of a curved one.

Ending

In the Japanese version, you get different congratulatory messages depending how many times you finish the game (up to six times). This was removed in the international versions.
