Answer:
Dude, not to burst your bubble or anything but honestly hackers completely ruin the game for everyone else playing! Instead of hacking, try practicing with every gun and see which one you like; maybe you'll find one you really like! My personal favorite is the P-90 if you wanted to know.
Also, if you hack your wii, you run a risk of breaking the whole game system!
But anyway, people will give you more respect if you choose not to hack.
Just my two cents.
PS--- I know I didn't technically answer your question, but I hope I helped you make the right decision!
