the Cheat Database. Maximize this window if you
are having trouble viewing it.

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)
Now the input dialogue will open & make sure the Memory Pak is plugged in is ticked.
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 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

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
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.  
No 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 agame.So make sure you turn off any that you do not want back on beforeclosing.
Q: Where do i find cheat codes  to add myself into the
Cheat file?
A: You will find both PAL (E) and NTSC (U) Region Cheats on the
N64 Cheat & GFAQ Sites link on the side menu.

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 rea
Console Cheat devices,PJ64 does not need them.
Q: Can I search for my own cheat codes in PJ64?.
A: Yes Project64 1.6 Legacy will allow you to search and test it's result & add to the database through the GUI.
Goto Cheat Search  for more information.

without having to open the cheat file in a text editor ?.
A: Yes Project64 1.6 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.cbd file in a
text editor?
A: yes, but 1st: i'd have to say you dont need to, as you
can do allthis through the GUI but if you feel you want to then...  Open the Cheat File In Word pad, and then search the Name of the Gameand the 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:

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 and multi player options. The \ will group all the Cheats in one option Box with a + sign tothe left of the Box to open  There you will find every cheat that comes underthat 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
(S   = :53 (SPAIN) these are for PAL)

Q: How many codes can I put in a game, is there a limit
   and 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) anythingover 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 1.6 has the function.

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
Project64  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 F9On 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 and Press R for Full Health Etc.

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 dothey 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.

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 the50 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
Hex: 1,2,3,4,5,6,7,8,9, A, B, C, D, E,

and 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 thevalue 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 by4 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 and 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 add 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 and 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 and i meando not try to add NTSC (U) (Gameshark) Cheat Codes to PAL (E) Games.You will find both PAL  and NTSC Region Cheats on the  N64 Cheat & GFAQ Sites
link on the side menu.
