Greatest Heavyweights (Genesis)

Play as ranked competitor modifier in Career Mode
FFFLAD: 00??
NOTE: This allows you to play as anyone that is ranked in Career Mode. If you play as Mike Dixon (the champion), you'll defend your title against the #2 ranked boxer. Whether you win or lose, you'll go on to face the legends after that match. Also it will take Mike Dixon (or whoever you're playing as) & make them one of your created boxers. If you have two created boxers & neither one of them are highly ranked, when you are facing the legends as Mike Dixon, instead of being paid $7 million dollars for the fight purse, it will say N/A. If you play as one of the other ranked boxers from #2 on down, you will play as the boxer that's ranked at that point. If you win, whoever fills that rank after the boxer you played as moves up, that's who you'll play as. In order to control just one boxer, turn the code off & you'll play as that boxer.
01 - Play as the #1 ranked boxer (Mike Dixon)
02 - Play as the #2 ranked boxer
03 - Play as the #3 ranked boxer
04 - Play as the #4 ranked boxer
05 - Play as the #5 ranked boxer
06 - Play as the #6 ranked boxer
07 - Play as the #7 ranked boxer
08 - Play as the #8 ranked boxer
09 - Play as the #9 ranked boxer
0A - Play as the #10 ranked boxer
The higher the value, the lower the ranking. Using a value higher than 1E will cause the game to freeze.

Play as ranked competitor in Tournament Mode
FFFDE9: 00??
NOTE: This allows you to play as the ranked boxers in Tournament Mode instead of the legends. You'll also face another ranked boxer. When it goes to the match results, it will still show all the legend portraits. Your portrait is Joe Frazier's.
01 - Play as the #1 ranked boxer (Mike Dixon)

Again, the higher the value, the lower the ranking of the boxer you'll play as. 1E is as high as you'll be able to because the game will freeze.

Infinite Round Time / Minutes Modifier
FFF036: 00??
NOTE: This code can be used in 1 of 2 ways. 1st, you can use it as an infinite round time code or 2nd, you can modify how long each round is. However, in order to do this, you must turn the PAR on before the round starts & turn it off during the match. If you keep it on, time will not tick down. If you turn it off & don't turn it back on, the next round will be a standard 3 minutes.

04 - 4 Mintues
05 - 5 Minutes
06 - 6 Minutes

Infinite Round Time / Seconds Modfier
FFF038: YYXX
NOTE:
XX - Left digit (10's)
YY - Right digit (1's)
This code can be used in 1 of 2 ways. 1st, you can use it as an infinite round time code or 2nd, you can modify how many seconds each minute has. XX Modifies the left digit; YY Modifies the right digit. In order to create the number of seconds in a minute See this example: To have 35 seconds on the clock, the value would look like this: 0503. You can also go well beyond the numbered digits. You can use this code as an infinite round time code or 2nd, you can modify how long each round is. However, in order to do this, you must turn the PAR on before the round starts & turn it off during the match. If you keep it on, time will not tick down. If you turn it off & don't turn it back on, the next round will be a standard 3 minutes.
01 - 1
02 - 2
03 - 3
04 - 4
05 - 5

Power is well beyond maximum limits
FFF1A0: 006B
For some reason this also seems to make your opponent's punches ultra powerful too. I've played numerous matches where I got floored with a single hook or uppercut. Use a lower value if this is doesn't work for you.

Speed is well beyond maximum limits
FFF1A2: 006B
NOTE: Sometimes if the setting is too high, left will move you right & right will move you left. If its set too high, it can also make you excruciatingly slow. Use a lower value if this is doesn't work for you.

Stamina is well beyond maximum limits
FFF1A4: 006B
NOTE: Again, if this is too high, you won't be able to throw punches in quickly. When you throw a punch sometimes, your arm will stay extended for a second or two, which leaves you open for attack. Use a lower value if this is doesn't work for you.
