    [I highly suggest you test your codes on something like a real game cart, if you still have anything that old, or on an emulator like VBA - also, GameYob currently only supports 14 strings of code, not full complex actual codes]

    This is very easy, and it is broken down into 3 steps:

    1: The original code
    2: If it is enabled or disabled
    3: The name of the code

    First off, find the code for waht ever game you want, I'll go with Pokemon Crystal, because I'm hardcore. Lets try the shiny pokemon code: 910730D2 . From here, you format you code like this

    1: Basic code

    910730D2

    2: Basic code + Enabled/Disabled

    910730D2 0 - Disabled
    910730D2 1 - Enabled

    3: Basic Code + Enabled/Disabled + Name

    910730D2 0Fight Shiny Pokemon - Yes, there is no space after the 0 or the 1.

    Saying you just want this code for now, save it as the name of your rom, mine is "06 Pokemon Crystal.gbc - in this case change the .gbc to .cht ["06 Pokemon Crystal.cht"]."

    Saying you want a longer code, this can be done, the only current restriction is that you can only have 14 lines of code per cheat file. Lets add a longer code like Walk Through Walls.

    010AA3CE 0Walk Through Walls 1
    010AA4CE 0Walk Through Walls 2
    010AA5CE 0Walk Through Walls 3
    010AA6CE 0Walk Through Walls 4
    9100FAC2 0Walk Through Walls 5
    9100FBC2 0Walk Through Walls 6
    9100FCC2 0Walk Through Walls 7
    9100FDC2 0Walk Through Walls 8

    Just enable all codes at once when using a code like this, I suggest you always set codes to be disabled [0] to start out with, and just manage them while you are in game. Now lets get these rascals guys.

    I found quite a lot of cheat files for GB and GBC:
    GB .CHT Files
    GBC .CHT Files

    They're in the BGB cheat format which appears to be the exact format you describe.

    That is some spooky scary stuff, using those files you could edit the information contained in them, and rearrange as you would see fit. If anything is missing, you can now add it manually.

    There's nothing spooky about it, I used that format on purpose, since it has existing cheat packs and is easy to edit by hand.

    There's no particular reason I can't increase the number of cheats. LemonBoy, the guy who implemented cheats, set the limit to 14. I think I can make it as high as 100 without memory being a concern, I'll just need to implement scrolling in the cheat menu.

    100 is very very good, I'd suggest having side scrolling if you could manage that, I think that would be nicer than just a long list.

    Up to 100 cheats are supported now. I don't know what you meant by side scrolling, I decided to organize it in pages. You can press L and R to move between pages.

    I tried your method and it didn't work. I managed to use an infinite star chips code for Yu-Gi-Oh!- Capsule Monster GB on VBA and it worked like a charm. However, even using Cheat2Cheat, it won't work on WoodR4 which is what I used to test the code. It's only one line and that's all I used. I converted it to the .cht format using the Cheat2Cheat app and it didn't work. Now, I guess I'll have to play the game with 99 chips. :(

    I'm not familiar with Cheat2Cheat, but as far as I can tell it's only for gameboy advance games. You should open the created .cht file with a text editor and make sure it follows the format described here.
