GAMESHARK TUTORIAL

To write Gameshark codes you need to know a few basic logarithms, which are used in Gameshark codes, and fully understand binary and hexadecimal code.

Decimal - Hexadecimal - Binary
0 0 0000
1 1 0001
2 2 0010
3 3 0011
4 4 0100
5 5 0101
6 6 0110
7 7 0111
8 8 1000
9 9 1001
10 A 1010
11 B 1011
12 C 1100
13 D 1101
14 E 1110
15 F 1111
16 10 10000

Binary and hexadecimal code.

Binary code is a very primitive yet still widely used computer code. Old computers such as the Apple 2E, were only able to process code strands of ones and zeros. Binary code was created so digits such as two thru nine could be understood by the computer. The only draw back, was that this took a large amount of space and time to process information. Later, once more sophisticated processors came out, binary code was transferred to hexadecimal code, which took less time to process than binary. Hexadecimal is the most commonly used computer code today.

How the Gameshark works.

All Nintendo games are written in ASCII. A Gameshark intercepts all the strands of code being sent from the game cartridge to the Nintendo and translates them into hexadecimal code. Then the Gameshark ads which ever codes have been entered by the user, and then are placed "nicely inconspicuous" into the strands of code. The Gameshark then translates the info back into ASCII, and sends it to the Nintendo.

What makes up a code.

First of all, every Gameshark code strand has 8 digits then a space then 4 more digits.

12345678 1234

12345678 The front

1234 The tail

To make it easier to comprehend this, break the first 8 digits into 3 parts and the last 4 digit code as a 4th part.

(PART 1) (PART 2) (PART 3) (PART 4)

(PART 1) is a 3-digit bit used to tell the game cartridge what type of code will be used.

810 - Basic code beginning which will be used to access parts of the game cartridge, which will then go through the GS to create an effect, which the game cartridge can not produce.

880 - Basic code beginning which will go through the GS to create an effect, which the game cartridge can not produce.

D00 - Basic code beginning used to modify aspects of the game which were used for designing the game and were meant to not be produced by the game cartridge.

(PART 2) is a 3-digit bit used to tell the game cartridge how the code will be used. It also supplies data for how the code will work in the game.

3-digit data bit - used to designate the code to certain parts of the game such as levels.

696 - Basic code bit for designating that the code would show up on the cheat menu in the game.

(PART 3) is a 2-digit bit used to tell the game cartridge how the code will be used. It also supplies data for how the code will work in the game.

2-digit data bit - used to designate the code to certain parts of the game such as objects and cheats.

3C - used for codes editing health in 1-player games.
FF - used for codes editing ammo in 1-player games.
F3 - used for codes editing weapons in 1-player games.
F5 - used for codes editing health against enemies in 1-player games.
75 - used for code editing clipping and map settings.
3D - used for code editing clipping and map settings.
2 digit data bit - used to designate the code to certain parts of the game such as objects and cheats.

(PART 4) the 4-digit bit at the end of a strand is unexplainable and is used for data work in Gameshark and game cartridge.

0000 0001 0030 0007 3F80 3C80

The following are all of the 2 bit and 3 bit data codes. There are formula codes to get you started on how to use them.

Cool guys, thanks for all your support on the issue, and know hacking is not easy I assume that is because of the mechanics of a game, and the fact that each game is programmed different, which can make hacking it a lot more difficult, also i often wonder how the guys at GS central hack codes?

[rimsky82]

dlevere, those tutorials look like a lot of bs to me. No good at all. There are much better tutorials on our own site.

dlevere, those tutorials look like a lot of bs to me. No good at all. There are much better tutorials on our own site.

I just copied and pasted them from my message board, which is for new hackers.

[rimsky82]

Well, I would have no problem with it, except there is information in both of them that is just completely wrong. I won't get rid of them, or even demand that you do. But man, people writing tutorials full of guesswork without knowing the facts just isn't cool.

[jin299]

Dievere, would you be able to post some hack tutorials from your own site if possible?

Hackmaster can I ask you a question if I may about hacking, I always wanted to hack my own unlock everything code, but never knew how, could you tell me the method to hack this type of code?

[dlevere]

I don't know how to hack an unlock everything code. An unlock all doors code might be similar, I don't know.

There are a lot of ways to hack a code to unlock all doors. I use one similar to the event done code - that is, save in a place by a door that is locked and start an unknown search. Now at the door do equal to. Unlock it, and do different to followed by equal to. Then load it back up and keep repeating this.

[jin299]

That sounds like a cool code, Ill definately, have try it out? do you know any other hacks, that aren't mentioned on the web, what about a invicibility code, any idea how to hack it?

Hacking Untouchable/Invincibility Guide By Abystus

[dlevere]

This isn't for the PSX, but I found an old tutorial that shows how Lik hacked this invincibility code for the GameBoy:

Invincibility Codes
by Lik

Hi people! This is Lik back with another Game Boy Hacking Tip. Many of you had flooded my email with letters wondering how I hacked that Invincibility (walk on spikes, and enemies go right thru you) for Mega Man Extreme for the Game Boy. Well today is your lucky day because I'm in a good mood and I'll let you in on the secret of hacking that code. So go grab your Game Boy, your GameShark and a copy of Mega Man Extreme and let's get cracking… oops, I mean hacking!

1. Get into the game and go somewhere where there are no enemies and perform a Start Search.

2. Now get back into the game and walk around for a little while (stay clear of enemies) and do an Equal To search.

3. Repeat Step 2 once or twice to narrow down the possibilities.

4. Now walk around and let an enemy hit you, and once Mega Man is flashing, do a Different To search.

5. Now get back into the game and get hit again and once Mega Man starts to flash, do an Equal To search.

6. Repeat Step 5 once or twice to narrow down the possibilities some more.

7. Get back into the game and walk around away from enemies and do a Different To search.

8. Go back into the game and walk around and perform an Equal To search.

9. Repeat Step 8 a couple of times to reduce the possibilities.

10. Now check your results, if you don’t have only a couple left, Repeat Steps 4 through 9.

11. Now it is time to check to see what you have.

Now it's trial and error time. You must test out all of your results, but if you want to cheat you can check out the site to see what the code is. If you followed the instructions right, your code should look something like this:

91 00 45BA, 00 being the value when you stop your searches on Step 8. It is that way because 00 means that the flashing of your character is off, so if you ended your search on Step 4 the value would be 01 meaning that the is on (makes you invincible for a short time). Now set the value to 01 so it keeps the invincibility on all of the time. There is your code.

That wasn't that hard, was it? You can also apply this method to other games that are similar.

[jin299]

Very, good find Hackmaster, I can honestly say I really enjoyed reading the tutorial, you posted, thanks again,

Also I remember previously reading some psx hacking tutorials, on codemaster project web page made by the same hacker, who made the invicibility hack tutorial you recently posted there, is there any way I could contact this hacker by the name of Lik via through email or a youtube account?

[dlevere]

Is there any way I could contact this hacker by the name of Lik via through email or a YouTube account?

No, Lik has been retired from the GameShark hacking scene for at least 10 years.

[jin299]

Well is there any other hackers like him you could recommend?

[dlevere]

A lot of the PSX hackers that I know are retired. There are a lot of hackers here at GSHI that still know how to hack PSX GameShark codes. What exactly do you want? A particular game hacked, or do you want to learn how to hack PSX GameShark codes yourself?

[jin299]

Cool, that's nice to know and I'd rather learn to hack gameshark codes myself, There's actually another question I want to ask you about hacking Hackmaster

when hacking a code, how do you know when a code needs to be more one line long and if so how do I find the rest of the addresses for the code, like take for example codes that are 2 lines long or four lines long, how are these constructed, are the codes addresses that are seprately condensed into one another, or is each address of the code located in the memory next to one another?
