Emerald Blue GC controller
G&W Octopus
Holy crap, that emerald GC controller looks so sleek and nice! Man, I really need to get one of these since japan got all the cool colored controllers.
Just what I was thinking, I love that controller! 
The Emerald ones get pretty pricey but I was able to get this one for under 30 because there was a catch....
The seller stated that the left analog stick didn't work correctly. From reading that I assumed it was loose or something, as a lot of used controllers are. What I normally do with loose left sticks is desolder them and switch them out with the C-Stick since they don't get regular use and are typically more firm.
When I finally plugged it in I found a different issue. When ever I move right the game reacts as if I'm inputting a little bit up as well. Maybe 10 to 15 degrees. The same effect happens when I move to the left; the system acts like I'm also putting pressure down. When I try to move the stick directly down the game system acts like I've only moved the analog stick half-way down. -Same with up. It's almost as if its not calibrated right. I tried unplugging and using the reset controller command to no effect.
I figured that the module was simply bad. So did what I regularly do: changed it with a replacement. Once set up again I found that the controller was still behaving in same manor. I checked the PCB and didn't spot an obvious shorts or bad traces. The few caps that are on the board look good too. Got any ideas on what the issue is? I guess if I really have too I'll swap out the whole board, but I would love to keep the original board if possible.
