Query: YOU HAVE TO WRITE YOUR OWN CODES???

i bought thise game shark and used it right away. it goes to this code page, of course, and so i figured i'd turn on some codes. NOT SO EASY! as i just figured out, u have to write ur own code. so i did that but it still didn't work. i can't figure out how this thing works at all. i tried to get infinite rare candies, like it did in the example but i couldn't get it to work. this product is not worth buying. Even with the detailed instruction manuel it is still impossible to figure out how to get these codes to work! DONT'T BUY, get a gba or gbc game shark! they are great!
