Supastarrio | Mario Kart DS Codes: WiFi Cancel Items @Supastarrio | Uploaded 13 years ago | Updated 5 hours ago
This code will cancel green shells, red shells, bananas, fake item boxes, and bomb-ombs. They will disappear the moment you use them.
Other players get affected by this code as well. Their items also disappear when they try to use them.
This code can also have some amusing side-effects, as seen with the chain chomp.

Meant for WiFi, but it should work anywhere.
