I broke Top screen connector, so I disconnected it and connect capture board into pc.
but, it showed only black screen.
First, I thought USB 2.0 cable may not work, so I bought USB 3.0 cable, but video output was still not worked.
Program recognizes the board type (N3DSXL), but video output is not working.
It's because of top screen connector missing? or my capture board broken?
I don't have soldering skill, so I didn't soldered anything. so not a soldering problem.
3/18 Edit: I received top screen connector from loopy, and it all fixed! it's now work well!
