Tool needed :

-Crystal Tile 2
-Any hex editor

1) Decompress arm9 binarie:
  1. Open your rom with Crystal Tile 2
  2. Click on the ds logo

  3. Right click on FSI.CT/arm9.bin and click Extract
  4. Don't close Crytal Tile 2, you'll need it again

2) Edit Arm9 binarie:
  1. Open arm9.bin with an hex editor
  2. Look for "98 00 00 00 9B 00 00 00 9E 00 00 00"

98 is the national pokédex number of the grass starter in base 16 = 9 *16 + 8 = 152
9B is the national pokédex number of the fire starter in base 16 = 9 *16 + B = 155
9E is the national pokédex number of the water starter in base 16 = 9 *16 + E = 158

(use a converter if you don't know how to calculate : http://www.kaagaard.dk/service/convert.htm)


Let's put kanto starters:


  1. kan.png
  2. Save the modifications
  3. Go back to Crystal Tile 2
  4. Right click on FSI.CT/arm9.bin and click Compression
  5. Save and close



And you're done =)

NICE post, man.
Where is the adress to change the starters that Oak and Steve give?

One more thing...
When I change the starters this way, Why my Rival always choose Chikorita?
How can I change this?

Thank you Very Much for help! xD

This is working fantasticaly!

however, I do seem to find an issue here: how do I get deoxys+ pokemons in here?

all of them have 3 digit codes (arceus has 1ED for example) and the game goes black when I attempt to select my starter if I modify one of the 8 zeros with one of the digits (Ex: 1E D0 00 00)

I'd really LOVE to have an arceus following me around >.< but this seems like a problem, any ideas???

All DS ROMs store data in a little endian format (Google endianness for more info). So, if you wanted Arceus which has the code 1ED, you would input ED 01 00 00 in the hex editor. ;)

You can change HG/SS starters in a more comfortable way by using one of my tool, DS PokeHack Studio. Even if it's in alpha state, it can already change starters ;)

Hi I'm doing what you have written but it wont let me save it.

Bumping because I'm having the same issue and PokeHack Studio doesn't seem to have a 32x version. I did everything in the tutorial but CrystalTile2 won't let me save it.


UPDATE: Though the program acted like it didn't save, the change was saved! It works! That was weird, but it works!
