Hi Merki, you installed the capture modification on my new 3DS XL console last year, it works great, however I only noticed now that the C Stick is faulty, I had always thought since I bought the console on release day that the C Stick was hard to use but I only just realised that is is clearly faulty now since I got a new 2DS XL and the C stick works flawlessly. Since it is now modified I can't send it off to Nintendo for repairs, I'm quite annoyed I didn't realise this sooner and I'm very regretful for not sorting it out.
Is it at all possible if I can send it your way and you can repair it?

Here are some video examples of the difference in functionality. (apologies for the bad lighting.)
Thank you so much.
