I bought an old 3ds because that was my dream since I was a kid. But the 3ds camera doesn’t work properly…
It just top black screen and then just freezes the system after a minute or if I just change to the front camera. But in homebrews like Space Riders it works only the back camera, but if I change to the front camera in the game it’s another black screen.
The calibration camera option also works perfectly, so I don’t know why is that happening 
(also, I’m from Venezuela, sorry if my English is bad)
