Regain energy:
Repeatedly tap Select after a round ends to regain energy.
Note: This may only be done once per game.

Lose half your energy:
Hold Select + Down before the first match to lose half your energy.
This code only works on matches after you beat Bald Bull for his title or after using the 777 807 3454 password, and only before the first match.
You cannot use the "Regain energy" trick in round two or three if you first use this code.
Although this code is not very helpful, but it may be fun for someone who wants an extra challenge.

Hint: Defeating Bald Bull:
Knock down Bald Bull once during the round before he does his bull charge.
When he comes at you, hit him with a body shot.
If you time it correctly, he should get hit and fall to the ground.
Repeat this one more time in the round to win the match and the Major Circuit Title.

Hint: Defeating Glass Joe:
If you wait 40 seconds, he will jump back and taunt you.
When he comes back down, hit him in the face.
60% of the time he will stay down.
However, if you want to be sure, hit him with the left.

Hint: Easy win:
To get an easy win, attack two or more times.
Then just watch until you see him blinking red and move to the left.
Swap him by rapidly pressing Up + A about six times, then he will block.
Keep repeating this until he is out.

Hint: Knockout retry (emulator):
Note: This trick may only be done if the game is played on the NESticle emulator.
Select "CPU", "NES Movie", and "Record" to capture your match.
If your boxer is knocked out, play the movie and stop a few seconds before your boxer is knocked out.
The emulator will start the game exactly at the point where it was stopped, allowing you to avoid the mistake that lead to the knock out.
