Hacking Supercard DSTWO not recognized by system

[bahamut920]

A while back, I bought a DSTWO and it worked fine for a couple of months. Now, neither my DS Lite nor my o3DS recognize the DSTWO. Neither system even reports a game in the cart slot. Now that I have A9LH on my 3DS and I can carry my entire library of physical 3DS carts around with me at all times, I'd like to be able to do the same for my DS library. I've tried formatting the microSD I was using, I've tried using a different microSD card. I think it's a physical connection issue, but I'm not sure if it's between the cart and the system or the cart and the microSD. Would cleaning the contacts fix the problem? If so, what's the best way to do so? I don't think a cotton swab would be able to get in between the plastic dividers to actually clean the connectors. Is there a good cleaning kit for DS carts anyone can refer me to, or a reasonably effective substitute? Is the issue something else entirely?

Use compressed air to clean all the contacts. That should help.
