Why are ppl asking for AR codes for a time based game? Just set the date ahead a couple of days to activate whatever missing games you need. Using an infinite timer AR code would be pointless since you can't win or lose until the time runs up. Using an AR code to obtain all medals would just be even more pointless because that ruins the whole game, since you earn records by earning medals.
Just play the game the way it was meant to be played.
I wanted a code to change the timer to the boss timer, but couldn't find one. I had to get a game with the boss timer from someone. (Thanks again, N64Mario. In case you want to add me for Showcase, my Wii Number is 4235 0953 6478 5204. I heard you have good Mega Man games.)
Worthy of mention is that the game's clock doesn't go backward when you set the DS backward, after having the DS set forward. (You could set the DS backward and then start the game from the beginning, followed by setting it forward one day at a time to get everything that's unlocked by days...)
"Please... never do anything as crazy as that again...." "...I'll think about it."
