I'm using the latest Akaio 1.4.1 on my Acekard 2i, and keep having the same problem with all my games. I will be playing them fine for a few days and saving frequently, and it will continue to work. Then just randomly, I haven't even taken the card out of the DS or done anything differently in the menus other than to select a game, the game will no longer recognize my sav file. For example(the most frustrating issue for me), I've been playing Final fantasy 4 and would get fairly far into the game after playing for a few days and then just one time I'd start up the game and the load game option would no longer be available as if I had no saves. I check in Akaio and the .sav file is right there, and its name matches the finalfantasy4.nds save name and I have tried renaming them, adjusting the ext with the files as well as in Akaio. I even took everything off the card and formatted it with Panasonic, then put everything back on and it still doesn't recognize the save when I start up the game. This has happened twice now with this game, and you can understand how frustrating it can be to get so far into it and the save work fine for awhile and then just randomly stop and force me to start all over. It's not just with FF4 either, several of my games have had the same issue where the .sav file is no longer recognized when I start the game up. I haven't used any other card or firmware before this either, it's a brand new Acekard 2i with just Akaio 1.4.1 installed on it from the get go and the saved games were all started on it. Any suggestions? Thanks!
