I have had an R4 Flashcard for the past 2 months (LOVE IT) but now I won an Acekard2 from Moonbooks.net and I just got it in the mail today. I have a 4GB SanDisk MicroSD Card FAT32 that I used with my R4-III. SO I backed that up and deleted it off my SD Card, and now I put the _ak2 folder in my SD Card Root, and then made a Games folder and put my ROMs and Saves in it, and then I put that file .nds into the __ak2 and loaded up my Acekard. What am I doing wrong? iT SAYS "Missing System File". I dont think it is the FAT of my SD Card because it doesnt say FAT error. I got FAT error when I didnt put my SD Card into the Acekard. I heard it click and it doesnt fall out when I hold it upside down. I am using the LATEST firmware from acekard.com for OSMenu of AK2. So...help me out here?
