* "Gradius II" (PC Engine) - Pausing the game and then entering the code Up, Up, Down, Down, Left, Right, Left, Right, II, and I activates full power. This code works more than once on Easy mode.

Simon is also limited to special weapons from the first game: Holy Water, Knife, Axe, and Cross. (Additionally, the Holy Water weapon gives the "static flame" from the original "Castlevania", not the moving flame from when Juste uses it.)
