Super Smash Bros. Melee
I have not played this game but have heard it is great.
Cheats:
Alternate Multiplayer Music:
Hold L or R when selecting a stage in VS mode and don't release it until the stage loads. The stage should play different music. Only a few of the stages have alternate music and you can't do this technique until you acquire the Sound Test. The stages this works on are:
- Icicle Mountain
- Great Bay
- Temple
- Yoshi's Island
- Onett
- Pokémon Stadium
- Kingdom
- Big Blue
- Battlefield

To unlock the Kongo Jungle from the N64 version of this game, complete the 15-Minute Melee. I'd recommend using Donkey Kong and constantly use his Down + B move the entire time (thanks to DEngel's Secrets guide, for I used that strategy to unlock this myself)!

Stage Unlock: Yoshi's Island Past Stage
To unlock the original Yoshi's Island stage from the N64 version of the game, use Yoshi and hit over 1,350 ft. (400m in the JP version) in the Home-Run Contest. To do such, stand next to the Sandbag and TAP the X or Y buttons to jump, then use the Down + A move to hit the bag for around 30% damage each time. Do that about 4 times to get the bag up to around 100-110% damage. Since you won't have much time left, get the bat and use a Smash hit to send the bag flying. If you did it all well enough, you should make it well over the required distance.
Transform with Zelda before battle
In Classic Mode, if you pick Zelda, you can transform into Sheik (or vice versa if you're already playing as Sheik) before the battle starts. On the match-up screen, hold Down (Control Stick) + A until the battle starts. You'll automatically transform before it begins.
