Hello, I have a problem with my R4 flash cart not working with my n3DS. I tried the R4 cart in my O3DS and DS lite, it works fine. However, the card wouldn't even show up in my N3DS. After installing B9S, I also did the setup to fix DSi mode so that's out of the way. Here is something that I suspect, sometimes in the past, I am kinda obsessed with my stuffs being organized so I deleted 3 or 4 titles with number in FBI in effort to organize those. I didn't think about it much since my 3DS works perfectly fine. Just until recently when I tried to play DS games, I discovered that DS mode isn't working. I tried a few fix suggests by others, formatting SD card, download various firmware from different R4 sites, but none of them are working. My flash card is a R4i 3DS, revision C I believe. I wanted to start by download and reinstalling every Title ID that related to DS mode but I have no idea where to find them. Any help is appreciated, thank you for reading.
