I got it on 2011 and when my psp charger is lost I didn't use it. I got a new charger last year and my old 4 gb memory stick is corrupted already. My cousin bought me the SD card adapter and of course it wasn't recognized. Months later it unexpectedly worked. It was preloaded with games and the 6.60 pro update. I was still new at the PSP homebrew at the time and I didn't update. A day later I'm just playing Super Mario 64 on the DaedalusX64 emulator and when I was hit by a ball in the game, Mario was stuck on the ground. I quitted the game and no roms showed up on the menu. I quitted and the adapter didn't work again. Tried to format it on my phone it still does not work. So I wanna buy a real Memory Stick now but I don't have any money.
