jam sessions because if you look in the video you can see the cart is really big and hangs out of the ds so i figure that its something you need to play the game so i think when you put the game in a emu on supercart its gonna say please reinsert the gamecard post your thoughts
If you're reffering to the videos I think you are, then I believe that's just the developer hardware. If you post a link to the video you're talking about I can confirm this. Also, the Japanese version of Jam Session Hiite Utaeru DS Guitar M-06 works fine on my M3 Perfect with Mini SD and Flashme v8a.
