Just type in anything like cheat01 or something in the encrypter, grab the decrypted code on right. then paste it in the shift + o menu but you have to paste the code you grabbed on the right and put in the parentheses in one of these lines:
passcode = "[paste decrypted text]"
passgallery = "[paste decrypted text]"
passtopless = "[paste decrypted text]"
Then that sets the code to whatever you put in the beginning, for my example I put cheat01 so i go to the cheat code in the bottom right and put in cheat01 and it should work.
