Anyone had a problem where the DS will randomly freeze, using the R4? This happened to me whilst playing a game (Anno, although I don't think that it matters). I tried a soft reset to see if the R4 was still functioning but the game had crashed, but the soft reset did not work which meant that the whole machine had frozen. I restarted the DS with the power switch but the game did not go into the R4 menu, instead to the NDS menu. For a moment I was worried and thought my R4 had died, but when I reset the DS once again with the power switch, everything was fine again. Any clues what happened or why, and has this happened to anyone else before?
