At the title screen, hold Select+Up and press B, B, A. The title screen's music and animation will stop to confirm correct entry, and the following button cheats will now be available:

• Press A the amount of times corresponding to the desired level number (e.g. 4 times for level 4) to start at that level.
• Press B for invulnerability.
• Press B twice for infinite lives and all items.

These inputs have not been coded into the Japanese version, but the effects still exist. Setting RAM address $C677 to a non-zero value enables invincibility and doing the same to $C676 grants infinite lives and all items.
