I have a GC third party controller (by ZedLabs, I know buying a legit controller is better but this one is just temporary) and it's loose. By that I mean that it doesn't get in a fixed position, and also it doesn't properly respond to inputs in a certain direction (up-left), which definitely makes some games unplayable. I've got through a few guides and know what to do, I'm just asking if this specific ZedLabs controller has a difference in its fixing and if there is a way to fix the analog without buying replacements. Thanks for any help.

By the way, here's a image of the controller for you to have an idea of what's up:
