I beat DS but not Wii, I am in mirror mode.

Beat both of them 100%

At what point do you "beat" Mario Kart? When you play through all the levels? When you unllock all the characters and karts? When you beat the staff ghosts? When you have 3 stars in all races and challenges?

I've beaten Mario Kart Wii 100%, but my sister hasn't given me a chance to play Mario Kart DS yet.

both 100% many times over

I've beaten all of the races, unlocked all the characters and karts, and beat some of the staff ghosts on MKDS. I don't even have MKW.

I have half of the Wii characthers. In DS I beat all the course with 1st places.

I have all characters in MKW (Including Mii Outfit B), beaten all staff ghosts, and gotten all gold medals in GPs. The only thing is I think I have to get three stars on the 150cc Special Cup and nearly all Mirror cups.

I haven't played Mario Kart DS in so long...wish my R button would at least work for me half the time these days.

I managed to beat at least half the staff ghosts, and about everything else. Getting Tri-star rank was probably harder to do, though.

That reminds me, I should check to see if my last friend code still works for Mario Kart...Hm.

Both 100% complete!

I didn't play MKW a whole lot, so I'm not far at all... On MKDS, though, I unlocked all characters and Karts, and I got at least 1 star on all of the missions and races. So when I go on Wi-Fi there's a star next to my name! ^~^

just need mii outfit b and i 100% complete both.

I borrowed Mario Kart Wii from my friend and I beat it in a few hours.

@Sableyed: On Mario Kart DS do you know about the Mario in the Kart when you first get in to the game. Well if you beat the game it will show all the characthers.
@TRDS: Lucky

I completely cleared MKDS getting three stars on everything including missions. MKW, I gave up on after a few months. There were way too many Blue Shells by the AI.

I beat the DS version. Working on the Wii version.

I've beaten all the cups in first place on Mario Kart Wii. Don't have all the characters, but if they expect you to do more than that it's really not worth it.

I know I'm bumping this, but to the day, I beat MKDS and have to unlock Bowser Jr, Baby Daisy, and Dry Bowser on MK Wii.
