So I need to replace the circle pad on the 3ds (the skin is teared up so I thought it was best to place the whole thing.) but I'm concerned about the capture card that was installed and that it won't work once the pad gets replaced. I have computers guys I go to when my pc needs to be fixed so I was thinking going over there and asking them to replace the pad but I don't what to say to them about the capture card. Hence why I'm making this post, I wanted to know what to tell them about the capture card and what advice to tell them about. Like, how do I tell them to deal with the capture card so they don't make it unworkable?
