While this thing royally sucks for a NES controller, it is great for a hacking project for PC. There are quite a few tutorials of mods people have done using arduino boards to replace the sensor with an accelerometer. Combine this with a Rift or Vive, and you have a pretty nice VR setup. The biggest issue will be finding one at a good price.

I'd put more stars but I ordered 3 and 2 of them quit working the very day I got them and I'm sure you have to work out and diet with them as well cuz it didn't do too much for me and they kinda hurt so be careful but if you are fit and in shape and just want to be tone I'd recommend it
