Nintendo game cartridges & Controllers

I am looking for the Super Nintendo and Nintendo NES game cartridges that do not work. I know a few people are selling them in working condition, but I dont see the point in me buying them if they work.

I also would like to get my hands on some nonfunctional controllers for the NES. Let me know! I just need the housing!

If you repair either one of these items & want to get rid of the housings of cartridges or controllers & need to get rid of them let me know!
