What to do with my old PSP e-1004

Hi guys, I found my old psp.
I've never used it before, it's probably ten years old, I don't know. I don't have any games, I connected it to my Ps3 via USB, but there's nothing to do with it, give me ideas other than the most obvious ones, like buying a disc (I already know that it wouldn't work for me without a disc)
