Iv used the panasonic formatter. Iv tried AKAIO 1.6 RC1 + 2. AKAIO 1.5. And also the latest official firmware. AKAIO 1.6 shows the menu and when i try to load a backup it freezes on the LOADING screen. Usually with green writing, sometimes red. AKAIO 1.5 didnt even show the menu i think it froze on a loading screen before the menu. The official FW loads backups but most seem to crash at the main menu of the game. Im thinkin about trying 1.4.1 to see if the card is fake... Also noticed this post in the forums and wondering if i should try it. Grab the latest AKAIO firmware, currently 1.6 RC2 = http://normmatt.com/forum/ Grab Official Firmware 4.07a15 = http://filetrip.net/f2445-Acekard-2-Official-4-07a15.html Take the file akmenu4.nds from OF 4.07a15 and copy it to /__aio/ak2loader/ Turn on Acekard and Navigate to a Game, Press Y Twice to open Properties Switch the option "AK2 Loader" from "AKAIO" to "AKMENU4" Hit Okay (A) and play game This worked, so just need to change every game to AKMENU4?? Wierd not sure why i had to do this but thanks to the original poster of this tutorial... Still the odd game not working but this is better than the OFW.
