Hi I have an Acekard 2i and a DS Lite (and a 3in1 but that's not an issue). I have the following problems: 1) Sometimes, but rarely, when I close my DS and re-open it the game goes black and won't come back. The system is still powered on. I can start the game again and play for many hours without it happening again, it just happens sometimes. 2) I notice that it takes a while for my Acekard 2i to initially load when I turn on my DS, which wasn't always the case. It used to be pretty instant, now it takes about 5 seconds on a black screen. Then the "loading" shows up, flashes white, and it performs normally. 3) When I go back to the "root" and try to select the microSD card on my DS, nothing happens. if I select slot-2, it says no slot-2 is inserted. If I reset the system it goes back to the folder selection and works fine, it's just when I press the B button and go to the root menu that for some reason the card acts as if anything is inserted. To clarify, I checked if this was a fake card and the website says it's real. I have a 16 GB microSD card. I reformatted with Panasonic to see if that would help, and it did speed up lameboy but that's about it. Thanks for your help. I don't think it's under warranty anymore.
