becareful with the connectors, it’s very brittle. I broke the display connector’s bracket in the process and it’s held with papers in between the display now 💀
i bought one off marketplace pretty sure its never been opened up inside, its super clean, japanese version I paid 80$ for it. I modded it with ps1, psp and gba and n65 games and I am so in love with this handheld, nothing will beat it. I've had raspberry pi handhelds, steamdeck, switch, all of that and the psp is still my favorite and the one I know I will keep it forever now. enjoy !
