I was watching a video of a guy installing cia 3ds games into a 3DS and he pulled the SD card from the inside of the system were you take out the screws which confused me because I didn't know that the 3DS had an SD card there I'm using the old 3DS which I bought years ago when it first came out. I put custom firmware on it luma3ds and FBI so my question is do I need to do that to install CIA games or do I just use the SD card on the side of the system? Cuz I just dropped $20 on an SD card from eBay a few hours ago and I would be pretty pissed if I need to get a micro SD card instead. Is it because he's using a new 3DS that has the MicroSD inside the system or do all 3DS have Micro SD inside the system and that's how you install cia's or do I just use the one on the side of the system and it doesn't matter?
