I got this one about a week ago, it was free so I shouldn't complain as much, but it didn't come with a memory stick or anything. One of my friends who has a PSP 3000 with a memory stick and everything tried to put a game in it (with a UMD disk, not an ISO). It never even loaded the UMD icon apparently. The test was apparently a while before I got my hands on it, so some information may not be entirely accurate. Anyways, since the problem seems to be that it won't read UMDs worth anything, what shall I do? If I do have to bin it, I'd like to get one that is a model 2000 or older, with a version of 6.20 or earlier, might anyone be able to put their superior searching skills to use for that?
