I just bought a EZ Flash Omega on Amazon for my DS Lite Cobalt Blue. I believe I got a bad unit or something. Mario Kart keeps randomly freezing on me. My ROM is a good dump and has the correct MD5 hash. I already updated the firmware and even downgraded it, yet the game still keeps randomly freezing. I tried different microSD cards and cleaned the contacts of the flashcart with rubbing alcohol, yet still I'm getting random freezing.
