It might be helpful to provide some details about what you're trying to do - which emulator/system, how are you trying to add palettes, etc.

@Ekstreme Can't really tell the exact "which one" without some digging, but they are the "around $2 a piece from china"-ones and arrived overly sensitive and erratic (check my fix video for it if you want to see the difference).
As I remember the NES controllers, I can't recall them being "spongy" like these are. This has not been a issue for me though. Don't know how they would fare in Track&Field type things yet.
