I have a PSP1001 with CFW M33 5.00-6. My home button seems to mute, along with doing whatever it does. (so if i'm playing a game, pressing the home button will mute the system, and bring up the quit game? screen) I can simply press the volume button to bring back the sound, but this happens everytime and gets annoying. Also, my "music note" button doesn't do anything (i'm guessing it's supposed to mute). And on top of that, if I play for 30min or so, small black pixels show up on the top right of the screen, and stays there unless i turn off the PSP for a couple hours. Anyone got any ideas on how to fix these?
