The Do's & Don'ts' Of Adding & Editing Cheat Codes.

Q: Why dont the cheats work in PJ64 ?
I ticked what i wanted to use but it does nothing on all games i have tried.
What can i do to make them work ?
A: Make sure you have enabled your Memery Pak otherwise cheats will not work !

To make sure it is go to options/Configure Controller Plugin (see picture below)

:: click to enlarge ::

Now the input dialogue will open

& make sure the Memory Pak is plugged in is ticked.

:: click to enlarge ::

Now click ok & Mem Pak is ready for use with cheats.

Q: Why can't i see any cheats in the Menu, it is Blank ?
A: Well this could be several reasons.
01: The game you are playing has no cheat support at the moment, so either follow the links

to a site to add yourself some cheats, or wait until they are supported for that game.
02: Make sure that the Project64.cht file is in the root folder (with the Project64 Exe)

03: There May be a memory hang caused by opening too many Roms after the other

this can cause the Cheat Menu, Rom Properties to display empty.

Just close Project64 and then reopen it.

Load your game and check if the Cheats are there.

04: Check your Rom with Goodn64 it might be because of the following reasons:
You have a Rom that is a Bad or Alternative Rom..

The Rom may have a different CRC and isn't recognised.

You can do 2 things here: to fix this problem:

04a: Check Paulob's "GoodN64 Bad2Good Patches"

and you will also need IPSWin 2.0 to Patch the Rom.

These are available from the superb Emutalk.net Downloads > Misc > Tools

and see if it has your Roms name in there, if it does then patch it to be recognised as the Good Rom version leaving you to play on with no problem at all.

04b: You would need to add a cheat into the blank menu for the game.

So just enter this example below:

Test Cheat

80123456 0001

Once you have added the cheat close PJ64.

Now go into the root folder of Project64 & open the Project64.cht file in a text editor.

In other words Double Click the Project64.cht File and it will open in Note Pad.

Search for your Games name:
In this case we will try Super Mario 64 = //Super Mario 64
so search for //Super Mario 64 if that shows nothing try without gaps etc

making sure you are the right Region Cheats you need once it finds it.

(JU) = :41 (1080) these are for NTSC
(J)    = :4A (JAPAN) these are for NTSC
(U)   = :45 (USA) these are for NTSC
(E)    = :50 (Europe) these are for PAL
(A)   = :55 (Australia) these are for PAL
(G)    = :44 (Germany) these are for PAL
(F)    = :46 (France) these are for PAL

So if its the USA Region you want it will be shown like this in the search

//Super Mario 64
[635A2BFF-8B022326-C:45] <<<< Arrow points to the CRC
Name=SUPER MARIO 64

Once you have found it copy the entire Cheat entry for the //Super Mario 64 to the end //----
and past it to the Bottom of the file under the one test you added.

//Super Mario 64
[New-CRC-C:45]
Name=SUPER MARIO 64

Cheat0="Test Cheat",80123456 0001

Now Copy the Test Cheat CRC over the original One below it.
Now delete the one above leaving this one the only new one added.

Save As and then say ok/Yes to overwriting the file and then close.

Happy Cheating!

Q: Is there a way to make Project64 Remember Cheats i have left on in a game

even after closing and reopening ? and if so how ?

A: Yes there is, On the Project64 Gui: Options\Settings\Options\Remember Select Cheats.

:: click to enlarge ::

Now Cheats on all Games that have been left on when you closed Project64 last

will be remembered and automatically enabled on the next load of a game .

So make sure you turn off any that you do not want back on before closing.

Q: Where do i find cheat codes to add myself into the Cheat file ?
A: You can find a list of links by clicking Emu64cheats link & then Cheat Sites.

Q: How do i add cheat codes in PJ64 ?
A: Click on the Adding Cheats link for a full explanation.
But please remember that you do not need to add Enable or Keycodes codes.

These are only to be used on the real Console Cheat devices, PJ64 does not need them.

Q: Can i add, edit & delete cheat codes in PJ64

     without having to open the cheat file in a text editor ?.
A: Yes Project64 1.5 will allow you to add, edit & delete through the GUI.
      Click the following for more information on Adding, Editing, Deleting & Using Cheats

Q: Can i add or edit codes in the Project64.cht file in a text editor ?
A: yes, but 1st:
     i'd have to say you dont need to, as you can do all this through the GUI
     but if you feel you want to then...
     Open the Cheat File In Word pad, & search the Name of the Game & Region.

example: Super Mario 64
Once you have, Make sure that you look at how the Cheats are written in the file.
example: Cheat0="Ostrich Mario",8033B3BC 0090
Cheat1="Mario Runs Backwards",8033B3BE 0070

Notice how the codes are written & how the code's are Separated by a Gap (Space)
like XXXXXXXX XXXX & not all in one code XXXXXXXXXXXX.

If it is a Modify Code that you would like to add Like:
example: Cheat5="Open Level Character Modifier",8125508A 00??
Cheat5_O=$01 Easy Level,$02 Easy & Normal Level,$03
Make sure that the Tie (Chain as it were) (O) Option:

Is listed somewhere below & shares the Same Cheat Number.
Also check to see if the ?? (Question Marks) are the same amount as the $00 (Values)

Also If you would like to right a note to the code like:
Cheat7="Play As Options",811653D2 00??
Cheat7_O=$07 The Big Green One,$08 Vikki,$09 Plastro
Cheat7_N=Here you can choose who you would like to play as.

But Do not use this with any other play as option.
The note will now be displayed in the cheats menu

when you click on the chosen cheat code option.

Now you may or may not of noticed the \ in the Active Modify Code Example.
This is what is used groupings (or in plain English)

It is used to group certain cheats together in the cheat menu.
You are most likely to find them in player 1, player 2 or solo & multi player options.
The \ will group all the Cheats in one option Box with a + sign to the left of the Box to open There you will find every cheat that comes under that option, already to be chosen.

Important notice to remember:
Make sure that the ie (Chain as it were) _O= (Option) & _N= (Notes): are listed somewhere below & shares the Same Cheat Number.
Also check to see if the ?? (Question Marks) are the same amount as the $00 (Values)

Q: How do i know what cheats are for what region ?
     Also how would i know them from written in the cheat file ?

(JU) = :41 (1080) these are for NTSC
(J)    = :4A (JAPAN) these are for NTSC
(U)   = :45 (USA) these are for NTSC
(E)    = :50 (Europe) these are for PAL
(A)   = :55 (Australia) these are for PAL
(G)    = :44 (Germany) these are for PAL
(F)    = :46 (France) these are for PAL

Q: How many codes can i put in a game, is there a limit

& what would happen if i went over it ?
A: You can put 500 cheats in per game, IE: Cheat0 - 499.
You can put in 100 codes per cheat.

IE: Cheat0="All Guns",xxxxxxxx xxxx,xxxxxxxx xxxx, (up to 100) Codes per line.

If you were to put the codes in PJ64 through the GUI (Cheats Menu) anything over 500 cheats per game would crash it.
If you were to put the codes in PJ64 through a text editor, only the 0-499 cheats would show up in the cheat menu.

Q: Can i use Stacked Activators for hacked moves, in No Mercy ?
A: Yes you can, Project64 1.5 now has the function.

/Me hears all happy screaming No Mercy fans all over the world.

Q: I have seen this Cheat code on a site but it starts with a 50, 88, 89, D0,D1, D2 number.

Can i use this In the PJ cheat File.
A: Yes you can, infact there are already many many codes

just like it in the cheat file already..

Previous Versions of Project64 never had these capabilities

& have just been introduced into V1.5.
How this works will be explained a little further down.
The 88, & 89 Codes are GS/AR Button Codes, & they are available to use Via the F9

On your Keyboard to use on PJ for a Quick injection code like Press F9 for 99 coins.
The D0,D1,D2 Codes are Activator Codes & are used to activate the use of a Codes at a push of a button like Press L to Levitate, Press R for Full Health Etc.

Q: Is there any codes that i can not use because they are not supported ?
A: Yes, there are Codes that are not supported & all those codes are listed below.

Here is a list of codes that are & not supported.

Supported Codes: N 6 4 C O D E T Y P E S

Q: I have also seen this message on the (Pal Code) Action Replay sites saying

"Cant not be used with Equalizer" what is a Equalizer ? & can i still use them in pj64 ?
A: The "Equalizer" is a little Sister of the Action Replay cheat device

but works in just the same way as its big brother does.
The only difference now is, The "AR" is no longer in Production, & the "EQ" still is.
Yes you can use them codes with pj64.

Q: where can i get a full update provided by Emu64 Cheats for PJ64 ?
A: you can check for updates by clicking the Downloads link & then pj64 cht Files link

If the file is updated that is where it will be along with any previous versions.

Q: How do i use cheat codes in PJ64 ?
A: For a full Visual Explanation click on the Using Cheats link.

Q: You said something about Serial repeaters (patch Codes) how do they work ?
A: The 50 numbers = Serial Repeaters (Patch Codes) What they do is patch (compress)

100's of codes down to a small Patched Version.

example: California Speed Cheat2="Have All\Cars",50001504 0000,800AAE5B 0001
50001504 0000,800AAE5B 0001 = 21 Codes Changing by 4 Hex Higher in the last Digit

in the Memory Each time & the start off point is the 2nd code after the 50 Patch.

Take a look & count up the 4 Hex jump.
To help you understand how the numbers in Hex go up

The Hex Count goes from 0-9, A-F & then 10-19, 1A-1F & so on.
So where the Decimal count goes from 0-255 Its Hex Equivalent = 00-FF

so if you can imagine a decimal count of 0-31 the hex Count would be 0-1F

Dec: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31
Hex: 1,2,3,4,5,6,7,8,9, A, B, C, D, E, F,10,11,12,13,14,15,16,17,18,19,1A,1B,1C,1D,1E,1F

& so on & upwards, & that should give you the idea how the Hex Count works.

So then how do we make this Patch 50001504 0000,800AAE5B 0001

Well the 50 patch codes works like this.
You tell the patch how many codes there are & how much they change from each other.
Now this is a Serial repeater, Meaning that the main memory Address has the same Value.

The memory Address being the 3rd to 5th number & the Value the last 4 9th to 12th.
The 1st to 2nd code is a standard 8 Bit = 80 this also indicates that the value
will only be the last 2 digits & will only go as high as FF the equivalent of a Dec 255.

Lets look at the code we are going to see change from 800AAE5B 0001 - 800AAEAB 0001

800AAE5B 0001
800AAE5F 0001
800AAE63 0001
800AAE67 0001
800AAE6B 0001
800AAE6F 0001
800AAE73 0001
800AAE77 0001
800AAE7B 0001
800AAE7F 0001
800AAE83 0001
800AAE87 0001
800AAE8B 0001
800AAE8F 0001
800AAE93 0001
800AAE97 0001
800AAE9B 0001
800AAE9F 0001
800AAEA3 0001
800AAEA7 0001
800AAEAB 0001

See by looking at the last Digit of the address that it is going up by 4 Hex on each Code.
Now all we have to find out is how many codes there are.

So lets start with a plain 50000000 0000 to begin with until we know how many codes & what the increase is.

Starting from the 1st code we can count it up to 21 codes at a 4 Hex Jump each time.

We now know that there are 21 codes so we ad that in like this.
How many is 21 in Hex ?
The guide above tells us it = 15 so we will add that in 50001500 0000.
Good, now how many does it go up by 4, so we add that in 50001504 0000.

So now we add that serial Repeater to the 1st code 50001504 0000,800AAE5B 0001
& there you go, 21 codes brought down to the number of 2.

You can also add A long line of Patches that could amount to a huge amount but would look like 10 Codes.
but you could also have as much as 500 codes in one patch.

A Question of regions.

As i always say, & really can not stress enough.
Do not & i mean do not try to add NTSC (U) (Gameshark) Cheat Codes to PAL (E) Games.
You will find both PAL (E) & NTSC (U) Region Cheats on Emu64cheats then Cheat Sites
