You're wrong, twice (and lol about the "hack the game").
Of course you can cheat with the Wii (use GeckoOS for your retail Discs/cIOSCORP/UNEEK+DI, or use your Loader, all have an option to apply cheats, some can even download the cheats for you (CFG, GX and WiiFlow). Also, there is a cheat for this game, it's only one right now, and not the one you would like, but anyways...
If you don't have any USB-Loaders, you can also use AccioHacks, which will do the same for you.
Oh, and don't use cheats online. You would not only be a giant douche, but Ninty can also ban you.
