None of those will work with GameYob, as it uses its own unique cheat format.

Ive tried to follow the guide to add cheat codes for Pokemon Blue, but it never finds the file when I click "manage cheat codes" in the menu. Everything is identical as far as names, I changed the extension from txt to cht, and I've made sure there is no space between the 0 and the code name I entered.

What else may cause this problem?
