CaitSith2's Mario Kart DS Time trial code viewer/verifier
Welcome to CaitSith2's Time trial code viewer/verifier.
First off, to get a code, you need to go to the record screen
of the course you wish to show off. (So that your viewing your top record
of that course.)
Once you are there, push Up, Down, L, R, Y, A in that order.
This should pop up a code. This is the code you enter in here.
