As you know, my PSP 1000's stick has seen better days. It drifts like crazy on some games. Games confirmed to drift so far are Burnout Legends, Afterburner, Rock Band, etc. So I'm understandably pissed off with it. Oddly it doesn't seem to affect Dissidia or Soul Calibur. So I'm bidding on a replacement stick on eBay. it's coming from China so truth be told I don't trust it, but its only a quid so no harm no foul, really. But with it coming so far, it probably won't be here for weeks. So I'm looking at opening up the system, giving it all a damn good clean and hoping that helps a little. To that end I have purchased a set of small screwdrivers, the sort usually needed to open watches and the like. They're the cheap crap ones from Wilkinsons but they should do. I've watched a vid on Youtube regarding the location of the screws and how best to clean the system, but I figured I'd ask the pros before attempting anything. So here's what I want to know: - What are the risks to the system if it's opened and given a damn good clean? - Is cleaning the connecions likely to improve the stick's responses, or are the problems more serious? - Could this possibly be endemic to Prometheus 5.50 as opposed to the actual analogue stick? - It doesn't drift at all in the web browser or while playing certain games. Why does it only seem to trigger with certain games? - Anything else I should know before attempting this? I'm notorious for being as far away from technically minded as you can get, so please explain in simple terms. Imagine you're teaching a five year old how to fix his PSP and you're pretty much there.
