So, i got my DSi the first day it came out, along with a AceKard2i. Works Perfectly for like a year and until today, i have no idea why, but it just suddenly doesn't want to work. It started "not working" in a later time, but before that time, it was working fine. So i'm using the newest AKAIO, etc etc. So i'll just get to the point, so when i boot it up, it gives me this Jap message. I can read jap so i said something like this "???Error has occurred???? Switch it OFF. ?????Manual" something like that. i got that message before, and i just lightly tap the power button to return to the menu and it works, but now, i try that method, it just keeps giving me the error message. I tried re formatting my SD card to a FAT32, still doesn't work. I'm using a Kingston 2GB Micro SD Card. So yeah, that's my problem. And yes, i can refund it etc but i want to know how can i solve it for future purposes.
