I am at my wits end. I have a new dstwo. I added the necessary files to the micro card, but the dsi will not recognize it. it says nothing is in the game slot. It is one 1.4.5. I updated the dstwo on a older dsi. still nothing, I tried older firmware still nothing. The dstwo works in a older dsi i have but still nothing on the other one. So i know the dstwo is not the problem but what is? Any help will be appreciated. The dsi works because it plays regular game carts!
