I saw this at goodwill and had to grab it. They were nice enough to let me test the unit first, so I was able to verify the rockers were still good. That's something to always check if you're buying used gaming hardware, those rocker buttons can either be pristine, or the machine may have been run half to death, and you won't know if you don't check.
I had a PSP-1000 once, and traded it in at gamestop for a credit on the PSP-2000. I LOVED the PSP-2000, it was a fantastic system, and it's emulation capability and web browser probably saw more hours dropped into it than the official games ever saw. I think I had eight of them?
Sony was vehemently against such use, and would often block such functions with periodic software updates, often mandatory for playing later games on the system. For instance, the PSP 1000 I have is running system software 2.0, which is highly customizable. Later versions flat out block any modification.
When my 2000 died, I bought a 3000 refurb, and was displeased to find out that one came completely blocked. You can mod that one slightly, but you have to do the trick EVERY TIME YOU BOOT the thing. It's nuts.
I've also completely forgotten HOW I got my Emu on, the terms that stick out in my mind best, Amber-Bock and Shiny-Bock Sadly happen to be beers. I believe those titles were meant to be puns, but they've made searching a stone you know what.
Any further discussion of such things would probably hit the rule wall.
I'm nervous to play any games on the thing, as you can't really roll back to an earlier version if you "get it wrong". Flashing the bios on ANY device is always a hard call, but in this case, if I wanted to play Vice City Stories, I would be forced to install an update that I know removes functionality.
(The PS3 originally supported Linux use, this feature was ALSO removed via "update")
Hostile updates are cowpoo.
