Instead of the enormous list of passwords that I used to have, I have cut it down to the necessary passwords for each version including my hacked versions as well.  If you still want to view the old page, click HERE.

  Note that the passwords for hacked roms such as Phred’s Cool Punch-Out!! and Bald Bull’s Punch-Out!! will send you to the hacked character instead of the original character listed on this page.
  The Japanese Gold Cartridge version of Punch-Out!! ends with Super Macho Man instead of Mike Tyson or Mr. Dream.  Even though the Tyson/Another World Circuit/Credits codes are programmed in the game, they do not work for the gold version of Punch-Out!!.
  Also, if you are having trouble with the Another World Circuit and Credits codes, make sure that you enter the first nine digits of the code first and then HIGHLIGHT the last digit of the code.  Then hold SELECT and press the A and B buttons together on the last digit to enter the code.  If you are using an emulator on your computer, these codes may not work if you are using a keyboard as a controller.  For some reasons, emulators will not read multiple buttons pressed on a keyboard making it impossible to enter the Credit/Another World Circuit codes.  Instead, use a Gamepad of your choice (sold separately).
