Analog stick getting stuck

A drifting analog stick is usually the result of a loose screw on the PSP shell.
If you flip your PSP over so you are looking at the back of it, there will be two screws on the side where the analog stick is, try tightening both of those screws (specifically the bottom one) with a small screw driver. If the problem persists, you can try to replace the analog stick yourself if the warranty has expired. If your warranty is still valid, you can send your PSP to Sony and they will repair it for you.
The UMD drive on the other hand, may be the result of dirty laser, or failing drive. Depending on the age of the PSP, you may be out of luck. The only option, aside from replacing the drive (which is expensive, and well, not worth your trouble) is to jailbreak your PSP to be able to play games from the memory stick. While downloading games that you do not own is illegal, backing up the games you own is ok.

Try calibrating your PSPs analog stick, here's how: 1. Go to Settings>System Settings 2. With the System Information screen displayed, rotate your analog stick in a circular motion (clockwise and counter clockwise). This will adjust the analog stick's range of motion. 3. Exit the Settings then run your game and test the analog stick. (it should be working well by now)
I hope this helps.

i know ur problem. Happened to mine as well, i had to replace the analog stick, it costs 5$ online, i cant give u link cause that'll be against the rules of this site, buut imn sure you'll google it and find and out. moreover there are some reviews out there as well which telll how to replace the analog stick, Best of Luck.

as a sony certified technician, i can tell you that these types of problems are caused be what we call a "false Contact". When the psp's analog stick does not touch the motherboard component, the analog stick auto scrolls down. If it auto scolls up then is just dirt biuld up. But if it scrolls down, make sure the screws on the back of the psp are FULLY tightened so that way the analog sticks makes contact with the motherboard. I fix psp's for fun so if you have a question that need to be answered right away, please just call my cell phone Number (773) 351-2426 (USA, ILLINOIS NUMBER) hope that works

do you have a warranty? if so call up microsoft and you can send it back and get a new one free of charge!

Provided you havent taken you PSP apart and moved the analogue stick try calibrating it before starting the game.

Go to Settings/System Settings,
Select system information,
Once the MAC address is displayed rotate the analogue stick in a circular motion.
Exit the screen and Voila one calibrated stick.

Sounds like you need to replacement. You can find them for about $10 on eBay and replace it yourself.
