Hey guys! First post, so I'm more than just a long-time lurker officially. My R4 for the original DS was stolen, so I decided to try the Acekard2i after researching how good it was online. I bought two of the cards from RealHotStuff along with two 4GB SDcards from the same retailer. (Sandisk) I am running AKAIO 1.8.6 I have a DSiXL and a smaller normal DS After seeing the popularity poll and all of the good things people said, I purchased two cards (One for my girlfriend and one for myself) When I first encountered errors, I used the newest version of SD Formatter from the official website to format my drive. I have the Zip file of my backup and the zipfile of my AKAIO firmware from their original states. I transfer the items to a folder. Then I transfer them to my Acekard2i. Every other time I transfer files (SAV or game) to the card, (When I boot the card via the DS) I get a weird issue where the files read with random unreadable characters and "?" marks. Akaio boots, but in this state, if I click a file.... The file just hangs forever. Sometimes, when I transfer files, it works just fine. Other times, not so much. Additionally, I have encountered an issue that whenever I try to back-up savedata by connecting the SD to my PC (by the provided T-Flash Hispeed USB drive), it causes fatal errors resulting in loss of data. (I have officially beaten Pokemon White 4 times.... It's a bit frustrating) I also encountered an error with where I connected the USB and all my .savs disappear. It reads them, but they .savs aren't there if I try to back them up. Very VERY frustrating. All my experience so far with this card has been like a hit-and-miss game of failure. I've spent more time trying to program firmware/fix the card than actually using it for playing games. I never had issues like this with my previous card, and I would like to think there's some extra-special thing I could do to make this an easy plug-and-play like my R4 running Ys was. I have yet to find 100% conclusive proof that my Acekard is a clone, but I do not think that is the case. I might try buying a new SD card tomorrow.... Any help/tips would be appreciated guys. Do you think it's the SD card, the Acekard itself, or the adapters? I'm open to suggestions. Has anyone else had similar issues?
