Mike Tyson's Punch-Out!!/Miscellaneous and Cheats

Miscellaneous

 * If your opponent's health is very low towards the end of round 1, but you haven't knocked him down twice yet, it might be a good idea to avoid knocking him down and waiting to do it at the beginning of round 2. Then you have lots of time to knock him down twice more for a TKO. This strategy is most important against Mr. Sandman, Super Macho Man, and Mike Tyson. Especially Mike. Of course, if you have already knocked him down twice, you may as well knock him down a third time for a round 1 TKO.
 * If your opponent gets knocked down and gets up on a count of 1, he will automatically fall down again as soon as you land an uppercut, even on a full life bar. This rule does not apply if the round ends before you knock him down again.
 * Every boxer except King Hippo shares a palette swap with exactly one other opponent. This means that their bodies look exactly the same except for the colors and the head, and they use many of the same animation frames. Therefore, a telegraph that applies to one boxer will often apply to the other, although the timing may be different. These are the boxers who share bodies and animations:
 * Glass Joe and Don Flamenco
 * Von Kaiser and Great Tiger
 * Bald Bull and Mr. Sandman
 * Soda Popinski and Super Macho Man
 * Piston Honda and Mike Tyson/Mr. Dream
 * No opponent ever gets up on a count of nine, except the second time you fight Bald Bull, who always gets up on a count of nine.
 * Soda Popinski was originally named Vodka Drunkenski in the arcade game Super Punch-Out!!. Strangely, his banter between rounds still suggests drunkenness. Either Nintendo wanted to avoid offending Russians, or perhaps more likely they just wanted to avoid references to alcohol.

Health regeneration
After round 1 or 2, you can press while Doc is talking to you. You will see Doc pumping his fist faster. When you start the next round you will regain a bit of health. If your health meter is full or very close to it, you will lose health instead (this can be done before round 1 to make the match harder). The code can be activated only once per fight.

Passwords
These can be entered at the start screen by going down to continue, and pressing or  to start entering the code and to confirm each number. Use and  to change the numbers.

Another World Circuit is a new way to take on the Major and World Circuit fighters. In one long circuit, you play through the King Hippo and Great Tiger matches, the entire series of World Circuit fighters, and the Dream Fight (with Mike Tyson/Mr. Dream being labeled as "Another McChampionn"). If you lose even one fight, it's Game Over. Unfortunately, if you can already beat the World Circuit pretty easily, this will not provide much extra challenge, but it can make the game a little more interesting.
