Dstwo flashcart problem on Dsi

Hi All, I am new here. I hope that you all can help me. 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.

 

1) the problem of your roms.
2) the problem of the micro sd card.
dstwo only support nds games. with the format xx.nds.

dstwo is a great card
seems it is a contact issue, you can try the paper trick

 

what does paper trick mean. i heard it can solve Poor contact problem. is that real?

 

like this: make the golden contact segment closer to the console

 

be far warned don't play multiplayer games via wifi system link only the new dsi firmware will disable access to the estore on the dsi
