hi guys i just brought a psp slim and a 4gb magicgate memory stick,when i on the psp slim,i need to wait for around 30 seconds before it loads into the xmb,sometimes it just show a black screen for around 30 seconds before the power auto switches off,also when i put the games into my memory stick,the psp slim could not read the memory stick,i tried it on my fat psp,it could'nt read it too,when i my psp slim with the memory stick inserted,it says i need to format my memory stick under system settings,when i tried format it,it says that there is no memory stick inserted,so i tried to format it using the computer,it couldnt format it too,my fat psp totally can't read the memory stick at all.So i tried using my 2gb memory card on my psp slim,it could detect it,but when i press the game,it just hanged and auto turned off.my fat psp version is 3.52 m33-3,my slim psp is 3.71-m33-2. Can anyone tell me what should i do to make my 4gb memory stick and psp slim work,thank you very much.
