Hello, I`ve got NDSL with R4iSDHC, my friend has DSi with R4iSDHC. We both played the same US version of Mario Kart. Game works perfect on share play, but when we tried to play local multi on 2 games booted weird thing hapend. It was able to create game, console saw eachother. But in actual game when my friend choosed Mario in my DS Mario wasnt controled by my friend - in his console the same situation. We should have different rom versions to play local multi in Mario Kart DS?
