How do you play as master hand on one player?

Answer 1

The Master Hand secret can be performed by doing these steps in two player mode:

Having two controllers, plug one controller in the third player slot while the other is in either the first or second player slot. The first/second player controller should pick their fighting character, while the third player controller should move their cursor down to the "Name Entry" option on their character slot. Put the first/second player controller on the "Back" option, then press A on both the controllers simultaneously. If the game does not freeze and goes to the level select screen, it was done correctly.

Answer 2

I found this the easiest way to play as Master Hand. You must use Game Cube controllers, so follow these steps exactly:

1. Take 2 Game Cube controllers, put one in the 1st OR the 2nd player slot and one in the 3rd player slot. (Note: This can work with Melee & Brawl)
2. Have the 1st/2nd controller place the cursor over the "BACK" button (do not press it).
3. Place the 3rd controller's cursor over the "Name Entry" button (again, do not press).
4. Make sure that both controllers press A at the same time.
5. If you did it right, you should be on the Stage Selection screen.
6. Whoever has the 3rd controller has Master Hand.
7. CONGRATULATIONS! You have mastered the Master Hand glitch!!
