I received my first of two R4is today (It took forever to arrive, so they sent me another as a sorry) and out of around 15 ROMS, only the two up the top worked; Dragon Ball Origins 2 and Animal Crossing Wild World. The others had a [?] next to the title where that little avatar was meant to be. It was like: [?] Zelda Spirit Tracks.nds. [?] Mario Kart DS.nds. [?] Mario Party DS.nds. And so on. I got my ROMS from a trusted site, and tested them on my DS emulator on my laptop, and they all work fine, they just don't work on the R4. I formated the SD, made sure I had the correct Kernal, I had everything needed to play, I just couldn't. Now, to make matters worse, Animal Crossing and Dragon Ball don't even work now. I'm using a Kingston 4GB Class 10, on an OG v6.3 3DS. It doesn't make sense how two ROMS could work, but the others couldn't. Could you guys dip into your mystical fountain of flashcart knowledge and help me please? Thanks.
