so i think this r4 blew my fuse and i needed to the f1 f2 fuse thing... god is R4 made by the m3 team weak!!!!!!!! anyway... i got a new dslite, and when i insert the microsd card in the r4, and turn on my ds, it will not turn on. i take out the microsd and it will turn on.... (before it broke my last ds, it was working ok lol... i mean... it would turn on ;-)
