Where can I find this replacement Part?

Sean Taylor - Reply

Hello! Unfortunately replacement parts for this particular model are difficult to find. There seems to be some replacement parts for the XL; however, I don't think that they are the compatible with the regular 3ds. Additionally, slot replacements are sold widely; however, it would require difficult smd rework. Your best bet is to find a New 3ds 2015 that is being sold for parts on ebay that has a working gamecard reader and use that as a replacement.
