Okay so ive downloaded the codes and ive gotten the compatible ones, but everytime i load it up from Nintendont it doesnt do anything, i looked into the launch settings and enabled cheats but it just freezes when i load up the game. i have a copy of the game and im loading the game from nintendont by loading the disc from there. am i missing something? can someone give me any advice?
Are you sure you’re selecting the right game version? If you’re on the Japanese version, NTSC-J 1.0 and NTSC-J 1.1/A do refer to different versions of the game, here’s how to tell which one you have: 
Otherwise you can try waiting about 30 seconds on Nintendont’s game selection screen before booting the disc, or connecting your Wii to the Internet before launching Nintendont.
I have an NTSC-U and i got the right codes i think i need to wait the 30 seconds or connect my wii to the internet, thank you for your help my guy!
