As the title says... I was able to score a PSP 2000 for free since it needed some repairs. At first I thought it was a simple matter of the battery being more than done (seriously, thing swelled up to the point it wouldn't fit in the battery compartment anymore ). But on a lark I tried plugging in its power cable to check out to see if it might still work... and saw that the screen was cracked. Thankfully I have the tools to open up and replace what need be done, but for that, I could appreciate some help. Simply... where/what would be the largest capacity battery that I could get inexpensively for this thing? The first and obvious constraint is that it has to fit in the battery compartment, since the factory battery has to be thrown away. Secondly... I know that Fry's previously had the CR-5400 adapter that seems to be just flat out legendary here on gbatemp, but looking more recently I couldn't find it explicitly listed anymore, but rather one that look-alike like it. Do these SD-to-MSPD adapters all work the same or what?
