I've looked through the codes, but I can't seem to find anything (sorry if I've missed it). So...

Is it possible to evolve crystal pokemon without trading via Gameshark?

Specifically for Golem.

First off we need to know what Pokemon game your asking about. Once you've answered that then we could better understand what exactly your asking!

If you don't want to cheat then you'll have to evolve it the normal way. That being catching a "Graveler" and having it evolve.

Hi. :)

I did say the pokemon game in the title. Crystal.

Graveler evolves by trading. I am unable to trade. So, I was wondering if there was a cheat for it.

Well actually the way you worded it, it was not clear as to what it was.

Then the answer is this: All codes that are not for the GBA games you will find via Google search. Game Shark is currently owned by MadCatz Inc. and is only offering official support for GBA games when it codes to codes. They also offer support for PS2 games.

Pokemon Crystel is a Gameboy Color game and the MadCatz Game Shark SP was never designed to be used on older games. So if you want to cheat then you'll have to use older game sharks that is no longer supported (reason being that it was not made by the current owner).

You can narrow your search by also trying GameFAQ's, tho that is just a guess since I am not sure that they do things for older games!
