Tried all this and it still won't work. In XMB-GAME-MEM Stick it says |There are no game| I have 3.71 M33-2. I created an ISO folder in the root of the mem stick. Put a 3 letter ISO with proper file attributes. When in the Restore menu and checked all settings and still the ISO game wont show in my PSP game menu
Any idea, please?

Is it an official Memory Stick?

If it says magicgate unknown/unsupported then it is a fake stick.

well i tried all the above but still doesnt work. Apparently my memory stick isnt legit aswell. Why is it for daxter, like surely metal gear should not be hack friendly

@PspXbox92

You need custom firmware installed on the PSP to play ISO games on it.

If you have access to a custom firmware PSP go HERE.

If you only have access to a Official firmware PSP go HERE.

Hi there,

I have a few questions too...

I have a 1.50 PSP and I've got Call of Duty Roads to Victory .cso file with me.

Can I just copy it to my ISO folder and play it? Do I have to download any additional software to play iso/cso files?

Moreover, for those iso games who are requiring latest firmwares; will it be possible to play on my 1.50 psp?

Sorry for my ignorance :); I will try my first iso game tomorrow

I am a PSP noob just bought slim and lite with 3.71 M33-2 and I followed it to the letter. But of the five cso files on my card 2 don't show, 1 shows twice and the two which show once and have a load screen both go black after loading.

What am i meant to do?

Thanks so much for these instructions. I am a PS noob and just got the PSP Slim with 3.71 M33-2 and followed this. All the ISO's I download are now working, Thank you so much. Cheers

For all those who want to work their games after they installed cfw to the psp, they must format the memory stick toa automattically create the necesarry folders(including ISO).You cannot simple create a iso folder and play the game, cuz it wont show.

When I look at the Information tab for my Memory Stick it says Unknown...so it's fake, how can this be when I have a genuine SONY MemoryStickProDuo MagicGate...
What's Up With That???!
