Nevermind, gaise, I downloaded another version of Gecko and it worked perfectly.
I was using 1.9.2b, 1.9.2 solved it.

omgHALPZME!

Gecko simply won't find my codes. It just says "SD codes not found". I did everything according to the tutorials, instructions and suggestions, downloaded my RSBE01.gct from Kittycorp itself, placed it in H:\codes, etc. And yet when I try to load the codes through Gecko, "SD codes not found". Has this happenned to anyone? Halpz?
