Yeah, idk how them are using but when i play mario kart DS online all the time i find cheaters with 300cc cars, and infinite powers (red & blue carapaces) i hate them!....please tell me what u think about nintendo WFC hackers, ^^ email me.
what you do is
1.turn your ds/dsi

ok so when your done and your in the race you press L,R,start,select, press them all at the same time,
but instead of it taking you to the menu it will keap you in the race and
it will slow make the cheaters stop for 1 min
hope this helped
p.s if you appreceat my work because i spent 2 weaks doing this then vote on my art work!
