So I have a hacked DSi with hiya CFW installed on the SD card. Just today I didn't have enough space on my 3DS for a game I was redownloading, so I decided to use the same SD card (which was very stupid of me). I downloaded the game, played it for a while, then stopped. A bit later I decided would play my DSi. I reinserted the SD into my DSi, but instead of it booting up like usual, the Hiya CFW thing showed up on my screen, then it tried to boot up. Then I got an error message telling me that something was wrong and to power off my DSi. I had a similar issue when I had a Pokemon Black 2 ROM on my sd, but I was able to fix it by deleting it from my sd. I hope that is the case with this issue I'm having, I really want to get back to using Hiya CFW!
Thanks!
Thanks!
