Everton, I just took a look at your code and I wanted to mention something. Your code changes the CC18 at ROM address $008D60 to 0018. What that's doing is changing the RAM address from FFCC18 to FF0018. That will prevent the game from subtracting from the number of turns/time, but now it's subtracting from FF0018 instead. Usually not a good idea unless you know what FF0018 is used for, and you know that subtracting from it won't cause any unwanted side effects. A better way to do it would be to change the subtraction instruction to a branch instruction. That way, you can achieve the same thing, but you're not subtracting from a different RAM address.

If you change the subtraction instruction so it just branches over itself ($008D5E:6002), this kills the subtraction, but you'll find that the game ends in a draw after the first turn. Not good. If you look at the programming, all you have to do to fix that problem is to branch a little further to get past the part that's causing the game to end in a draw: $008D5E:6012. You'll find that $008D5E:6012 does the same thing as your code, but without the unknown side effects. But, If your code is working and you don't notice any side effects, then you might be OK. Just wanted to let you know.

Thanks for fix my code but i have another problem and his name is:

George Foreman's KO Boxing

I need invincibility and infinit special moves


I am sorry for my BAD English...

Edit: I finally create the infinite special moves "AJXA-AA42", now i need only the invincibility.

As with most fighting games, George Foreman's KO Boxing uses the same routine for damage on both players. So if you make a standard Game Genie code for invincibility, both players become invincible. Ugh. But there is a way around that problem...

9VFT-BCD4 +
JBFT-AAD6 +
X3FT-ADD8
Player 1 has invincibility.

Also made a couple more codes...

JBFA-AAE8
Clock counts down slower.


BKFA-AAE8
Clock counts down faster.


I found where all the passwords are stored in the ROM, but didn't find any undocumented or hidden passwords (just the regular ones).

I was trying to create a code of invincibility for the "Street Smart," when I finally got it "AK4T-AA5E" the code works well but has a problem, both players become invincible. How to fix this?



The VisitntX's codes doesn't work on a real hardware!!!

This should help...

http://www.thegshi.org/?s=faqs&id=96

Thanks the link helped a lot. The end result was these three codes that I created 9TFT-BCH2 + CEFT-ADS4 + JEFT-BBH6.

Are working on real hardware but has a problem, money is not being computed. Any idea how to solve??


Edit: The codes I posted work only in the first matches. Man I give up

Last Action Hero...

ATKA-CA5Y
Infinite time.

Have only tested it for 1 and a half levels, but it seems to work fine.

You mentioned you wanted a "no car damage" code... I'm not very familiar with this game... where in the game do you get car damage?

the driving mission when you run into a car or semi your car gets destroyed and i really need infinte time on levels

i really appreciate the infinte time code thanks alot if you can find the code for car damage you will be a life saver you are already a life saver

Tony H there are two stages in the game where you drive a car. Stage 4 and 6 I believe.
