Gradius III and IV (PS2) Cheats
The following cheats can be entered at any time during gameplay in both Gradius III and Gradius IV. Press Start to begin entering each code, then press Start again to activate it. These codes only work if the Game Level is set to 3 or lower. Additionally, these codes can only be entered once, plus the number of stages you have cleared. For example, you can enter 1 cheat on Stage 1, 2 cheats on Stage 2, and so on. This rule counts for both cheats, so you will have to choose between them if you do not have credit towards both.
