  • Have "Gallery" written in gold writing on the main menu.

    After getting all 8 endings in Zero Mission, the font for "Gallery" becomes gold to signify that all endings have been obtained.

  • Harder Version of Final Boss

    Normally, the final boss fight is pretty simple-it only takes 5 super missile hits to kill him, if you target the core.

    However, if you achieve a 100% item collection rate, the boss will take 15 super missiles to kill, and will do 50% more damage, which varies with your difficulty level. So, if you have 100% on hard mode, the boss will take out three tanks with one swipe of his claw, instead of two.

  • Open New Time Attack mode

    To open Time Attack Mode in which you get a password for your clear time and percent, choose a file that has the green+yellow Samus symbol and hit the A button. When you see the 'Start Game' option, simply hit Up, Left, Right, then Down on the d-pad and 'New Time Attack' will appear.
