This is a first! Using a cheat device to hack another cheat device! If performed, this will actually create a paradox and will 
dissolve the space-time continuum.

Access Unused Hidden Developer Message 2 by pressing Up, Down, Left, Right at the Code Screen (Beware: Stripes:)
000B4B-13

NOTE: Tested to work with other Game Genie revisions. To display either message using any Game Boy that allows the Game Genie 
to fit inside of the Code Breaker, you must follow posses a Game Boy Code Breaker unit these steps:

1. To save the Game Genie code list onto the Codebreaker library you must remove the game cartridge from the Game Genie  
while at the code screen. (recommended you use a Game Boy cartridge that has no save RAM backup as the voltage spike 
resulting from removing the cartridge while the power is on will more than likely wipe out your save progress. 
I assume no responsibility for the damage, or loss of SRAM, etc.)
2. Hold down the "CB" button and press start to boot the "null" game. Release the "CB" button and you should now enter 
the Code Breaker menu. [B]333333333333333[/B] should be the recognised game header. This is the list where the 
Game Genie codes will be stored.
3. Input the patch codes and press start to save the codes as normal.
4. Enter the codes next time you start your Game Genie after the exiting the Code Breaker, 
with any game inserted and any code will take effect.

I guess it's only a matter of time before you can add your own codes to the database.

And if you already can, then go ahead and add them. No point leaving them on the forum. This isn't GScentral :P

Aren't you a Chronicler? Get to it, sonny. Chop-chop! :P

Edit: Added nensondubois to the Hackers group.

[ReyVGM]

I didn't want to add his codes before knowing if he could add them on his own. Some people don't like it when someone else adds their own codes if they could have done it themselves :P

But the point is moot, he can add his own codes now

[nensondubois]

Cool beans but I don't know how to add codes.

I have more Game Genie codes, but I encountered a slight nuance, so to speak. There are two revisions (at least that I know exist). My revision which has a Game Genie logo and some text (later version?) and the dumped (2.1) that only has the text as the second copyright screen. The less-known difference is that there are mapping tiles differences between the two revisions. I will provide codes for both.
Both versions have the same build date text. I'll have to unscrew the device at some point to see if there are any numbers on the IC chips that would give away the revision number on my undumped unit.

Cool beans but I don't know how to add codes.

Come on now, you know how to edit a wiki, but you can't add a code? It's 10 times simpler than a wiki.

1) Just enter the code page for the game you want to add codes to.
2) Click Add on top.
3) Enter the code and info.
4) Hit submit.

That's all

[nensondubois]

A'ight. Sounds simple enough.

The giving tree keeps on giving.. just when I thought I was finished with disassembling the Game Genie BIOS, there is one more thing.

Once whatever revision I have is dumped, their respective codes will follow.

[nensondubois]

Wikis required learning of syntax for performing operations, adding codes to a database is something I have never attempted before, also, excuse my laziness. :P
I can't seem to add anything. I attempt to add a code and it does not set into the list. Also, how does one add a game (in this case, the Game Genie)?

Game & Watch Gallery

Game select Music modifier (Some songs don't play at the right speed, so use the Mode Select Music Modifier for those. Sound effects are related to song playback speed because what signals the song to speed up or down depending on the game's current difficulty depends on a single write. Haven't determined the values which affect the song speed and no sound effect bit is assigned to the Mode Select.)

I can't seem to add anything. I attempt to add a code and it does not set into the list. Also, how does one add a game (in this case, the Game Genie)?

Just go to the game page you want to add codes to, select ADD from the top and then CODE. On the window that pops up, type the code and the name of the code, select Game Genie from code type, and enter your hacker name for credit. Hit submit and that's it. If you want to enter additional information, you can do it while you're adding the code or after the code is posted.

If you want to add a code to a specific Group, then just select the group name when adding the code OR edit the code and select the Group you want to move it to.

If you want to create a Group, then just click ADD and select Group. Type the name of the new group and hit submit. The group will be invisible until you add codes to it.
