You guys sure are lucky...
1. For me, I just got my 3DS XL the other day and got it updated.
2. Hence, I had to update my Acekard 2i using a DSL.
3. It all went okay, and I managed to start a game (the world ends with you) until the whole thing freezed,
4. Then there's the error screen requiring me to reboot.
5. After rebooting, the icon is has changed to the Acekard 2i icon and starting it results in an error screen, while booting it in DSL will have it "Loading" forever...
Oh ya, my Acekard is a new one, just bought it the same day as the 3DS XL...
Any ideas how to fix this?
I had the same issue twice - each time after updating the firmware of the 2i. Both times, it was resolved by connecting the SD card to a PC, copying all contents over, formatting the card and putting everything back in, minus AKAIO - then putting a fresh AKAIO installation on it.
I'd also like to report that this particular firmware update appears to have certain SDHC issues, and while most games work fine, new ones have issues. For example, Pokemon Conquest returns a FAT Error when played from SDHC while it loads instantly from a standard SD. Similarily Pokemon White 2 (J - patched with the 2.3 translation) loads forever and lags on FMV sections after (if is more appropriate) it does. Keep that in mind if you are interested in these two games.
