Tecmo Codes

The first code is a sound-test code. When you get to the Tecmo Super Bowl "Start Game" screen hold Left and press the B button. This will allow you to listen to all the music and sound effects in the game.

Tecmo's a great game, but if you really want to you can change some things about it. One of the only really useful ones is changing the time - so you can play longer quarters against opponents. Most of the code pages I found only told you how to change the quarters to 2, 10, 15 and 20 minutes, but I decided to go a step further and figure out how to do if for almost any time. The other codes are pretty useless, but I included them just to be comprehensive. You can use these in Nesticle by going to Rom Patch, typing the code into the code line and hitting enter, then highlighting the code and pressing toggle so it flashes.

APESOT - gives everyone a 100 Rating in every category

ZXTIOT - all starting offensive positions are played by the starting QB

The time code is pretty simple. You enter a two-digit code followed by UXLZIA to change the time. The second digit changes the first digit in the number of minutes per quarter, and the first one changes the second digit in time: so 15 minutes would be coded as 51. The code assignments go like this:

CODE:
A
P
Z
L
G
I
T
Y
DIGIT:
0
1
2
3
4
5
6
7

Unfortunately you can only use digits 0-7, so no 8 or 9 minute quarters are possible. So AP would be 10 minute quarters, YY would be 77 minute quarters, and ZL would be 32 minute quarters. I personally like using 6 minute quarters, but many prefer 7. Here are some useful examples:

PAUXLZIA - 1 min
ZAUXLZIA - 2 min
LAUXLZIA - 3 min
GAUXLZIA - 4 min
TAUXLZIA - 6 min
YAUXLZIA - 7 min
PAUXLZIE - 9 min
APUXLZIA - 10 min
PPUXLZIA - 11 min
ZPUXLZIA - 12 min
LPUXLZIA - 13 min
GPUXLZIA - 14 min
 IPUXLZIA - 15 min
APUXLZIE - 18 min
AZUXLZIA - 20 min

I'm sure you can figure the rest out. You can also freeze the timer for continuous play by using SXNXPZVG. I guess this is if you just want to practice for a long time. The remaining codes simply have to do with the point scoring, which I find to be pretty worthless. The one interesting thing you theoretically could do is ban field goals by making them worth nothing. Otherwise, these don't really do anything all that useful:

AAOATTTA - TD=0 for Player 1
AEOEVITA - TD=0 for Player 2
LAOATTTA - TD=3 for Player 1
LEOEVITA - TD=3 for Player 2
PAOATTTE - TD=9 for Player 1
PEOEVITE - TD=9 for Player 2
GAOATTTE - TD=12 for Player 1
GEOEVITE - TD=12 for Player 2
AAEALYPA - XP=0 for Player 1
AEEEUTPA - XP=0 for Player 2
ZAEALYPA - XP=2 for Player 1
ZEEEUTPA - XP=2 for Player 2
LAEALYPA - XP=3 for Player 1
LEEEUTPA - XP=3 for Player 2
TAEALYPA - XP=6 for Player 1
TEEEUTPA - XP=6 for Player 2
AEKAGGLA - FG=0 for Player 1
AAKEKGLA - FG=0 for Player 2
PEKAGGLA - FG=1 for Player 1
PAKEKGLA - FG=1 for Player 2
TEKAGGLA - FG=6 for Player 1
TAKEKGLA - FG=6 for Player 2
PEKAGGLE - FG=9 for Player 1
PAKEKGLA - FG=9 for Player 2
AASASIZA - S=0 for Player 1
AEKEIIZA - S=0 for Player 2
PASASIZA - S=1 for Player 1
PEKEIIZA - S=1 for Player 2
GASASIZA - S=4 for Player 1
GEKEIIZA - S=4 for Player 2
TASASIZA - S=6 for Player 1
TEKEIIZA - S=6 for Player 2

For this TD=touchdown, FG=field goal, XP=extra point and S=safety. Player 2 also applies to the computer player, if it's a one player game. And of course you can use multiple codes as long as they don't conflict, so you can change time and scoring, and make it so scoring rules apply to both teams equally.
