Could this controller just not be compatible with this adapter (which is known to only work with specific controllers for some reason)? Would buying the Mayflash one work? I'm not sure what to do. It only moves a tiny bit (like a 1 milometer radius) when the controller is shaken, so it most definitely not loose. What's even stranger is that all the buttons work, and so does moving perfectly left or right. Checking in control panel, I found that moving in those directions causes it to think I'm jerking the stick back and forth between that direction and back toward the center rapidly. I found that moving up, down or diagonally is (nearly) impossible. As already mentioned, one of the great advantages of using this method is that you can see the changes of multiple controller data types from the project. After doing so, I tried setting the controls in project 64.
When it came, I plugged it into my Boom N64 and PSX USB adapter, and went into control panel, and calibrated it. The description said that the controller's stick was tight (which it is), and working just fine on a real N64. Thorough and mindful research is crucial to making sure you get your hands on the best-possible project 64 controller setup. I ordered the controller off of ebay a few days ago. Potential sources can include buying guides for project 64 controller setup, rating websites, word-of-mouth testimonials, online forums, and product reviews. I have been having problems getting my original grey N64 controller to work with Project 64.
