Hi, I'm new here . . . I Just got a PSP Slim 2003 from eBay and don't know much about this stuff. It has 5.50 GEN-D (full) displayed in the settings menu. I read somewhere that it should only say this on Phat models, Slim is supposed to say 5.50 GEN-D3. Is this fine? I only want to use it for ISOs and emulators . . . Also, should I leave the CPU Speed at default or increase it? Are there any other settings I should change to get smoother/better performance? Thanks!
