Praise be
It's a good time to have a PSP, especially with Pirates! and Sonic coming up. Unfortunately, mine was on the way out. Second-hand to begin with, the analogue controller and one of the buttons were playing up, and so I headed back to CeX to ask for a repair.
I though I was to be disappointed - upon noticing it was running a hacked firmware they tried to avoid it - 'flashing a custom firmware voids your warranty'. I pointed out this was rubbish, as it was a hardware problem, and that I wanted a repair, not a replacement. At this point they sent a message to the repair department, who responded 'just give him another unit'.
And so I now have a mint PSP, in significantly better condition than my old one. The only cost to me: a couple of hours flashing it back to 3.03SE. So now I've an as-new device running Super Mario. Spiffing. And blessings on CeX.
