NES FCEUD codes by Abystus

ahh duh.

Is this code correct. Jaws... untouchable... PAR= 996607, Game Genie= YAVPVPTA ???
What exactly I'm I comparing? The compare number that was next to "9966" in the address is "06". The value is the last 2 digits of the PAR code which is "07". Does that mean that the compare # "06" does not match the value # "07", therefore you need to make it an 8 digit game genie code and not a 6 digit game genie code otherwise the game will freeze. Is this an example when a 8 digit game genie code is needed?
Now if the compare number matched the value number, then only a 6 digit game genie code would be needed?

Compare works like the below example:

if (Address == 6) //Our address is 9966 and our compare value is 06.
{
     Address=7; //This would write 07 if the compare above were true.
{
 else 
{
      //Do nothing and the value at that address would remain the same.
}

Basically before it writes the new value it will check the value at that address when it is applied. So with that in mind if we play a different version of the game with different fixes added to it then that address value may be changed because the underlying code has been moved to make room for the fixes that were put in place for the revision change. The check prevents the code from being put in place on an address who's original value does not match the compare.

So in your example if 06 had not been at that address initially then the code would not have written 07 and basically you would see no effect in game because the code did not apply the new value. Remember this is just a safety precaution so that codes don't crash your game when used on different revisions of a game or when the game changes it's asm routines on the fly. And yes your conversion to game genie is correct "YAVPVPTA".

It takes all of the codes together for it to work, not just the first line.

I tried that code and it doesn't seem to work though. It doesn't seem to hit anywhere. You said it is correct but yet I don't know why it's not working

[Abystus]

I came up with this code... "AEVSUVPA". Is that correct? I tried searching for DEEB by scrolling down the list but I couldn't find it. I then entered DEEB into the tab where it says "Seek to" and then it showed up.

That is correct. If you noticed below where you got that code it's already been converted to game genie in both 6/8 digit formats. So now you know how it all works .

I use both, hardware console and emulator.

I understood most of what you said. A debugger can be found in basically any decent emulator right? So using Nestopia as an example... i click on options > cheats. I enter DEEB in the address slot and 00 in the value slot. But what I don't understand is how to find the compare. Above these fields is the CPU RAM with 3 tabs: Index, R0, R1. Underneath each tab is lots or rows of numbers/letters. So how do I find the compare?

First thing download this emulator: FCEUXD SP 1.07

Next open your game in it, then go to tools>debug. A new window will come up, now just go to the address DEEB in the debug window and see what value it is set to with the code off (should be 09). That (09) is your compare value. After that put the compare value(09) into the second slot of the converter and the new value (00) into the last slot and your complete GG code will be displayed above.

BTW if your using hardware doesn't it have a 3 code limit anyways? Seems that converting codes longer than 3 lines is only going to provide partial effect at most. Just saying

Abystus.... you said to enter the PAR code in the Game Genie Code Converter 4.0 to make the code into a game genie code instead of a PAR code. I will use this as an example:

Ninja Gaiden (U) PAR FCEUX

Hit Anywhere DEEB00

When I open the game genie code converter 4.0 and I click on NES... the Hex Code slot has:
4 spaces where you can enter letters or numbers, then there is a " ? ", then there are 2 spaces where you can enter letters or numbers, then there is a " : ", and then there is two more spaces where you can enter letters or numbers. That is a total of 8 letter/number spaces.
The example PAR code I am using only has 6 letters/numbers. So how do I input a 6 digit code into the Hex Code slot which is 8 digits?

Your example code below:

First Field: DEEB
Second Field: Compare Value
Third Field: New Value (00)

To get the Compare Value you need to have a debugger (Find the address with the code off to see it's original value). The compare value is only used to compare against the value it is about to change. If it is true (compare is equal to the value at that address) then the code goes into place, otherwise the code is skipped (To prevent crashing the game if the original value was changed by the game to something else, or if the game version is different.). There is only need for a compare value if the game changes its value at that address at some point (most games typically won't but most people create 8 digit codes just to be safe), and mostly just a safety precaution. So if you generate a 6 digit GG code it still will have the same effect, however it won't compare before it writes the value.
