Well, one day I heard about a guy who transferred his PS2 Analog Stick to his PSP. This is a great solution to the PSP's nub being so small and having such a bad grip. Unfortunately, he didn't post a tutorial. So I tried my hand at it and here we go. **WARNING** You need something to grind plastic with.

1. Take a broken PS2 controller or one that you'll never use. You won't be able to turn it back into a regular controller.

2. Take out the small screws in the back of the controller.



3. Rip apart everything inside the controller but keep track of the Analog sticks.





4. Choose what stick you'll use but keep the other one just in case.



 



5. Look on the inside of the stick. Where that square hole is, that's where the stick connects to the controller and PSP.



6. Now take your grinding tool and grind the outer circular part on the bottom of the stick down as much as you can. Then grind down the little things that stick out diagonally from the square hole. Don't grind the hole though.



7. Now remove your PSP's analog nub. It's easy. Just pull up and it comes right off. No, it doesn't void your warranty. It was made to come off. Look at the bottom of this tutorial later on for a video on how to remove it.






8. Now place on the Analog stick where the nub just was and move it around. If it feels to stiff, take out that grinding tool again and do some more.





Now you can easily switch between the nub and stick whenever you want. And you also have a great grip! You've just saved yourself some money!

Here's the link to my video showing you how to remove the Analog nub and put on the Analog Stick.
