please help... It keeps saying "The Game Cannot be started"

I'm new to psp homebrew, so if anyone could help that would be wonderful, i'm using a fat psp, and i've only downloaded the original 4.01 update from sony...

I am going to say this once, and once only.

You CANNOT go directly from 4.01 to 4.01M33, it DOES NOT WORK.

You need to downgrade to 1.50 in order to get to 4.01M33 (if you have a phat, slim process is a bit different).

official firmware (4.01 in this case) > 1.50 > 3.52M33-3 > 3.71M33 > 4.01M33

You cannot run the updater without 1.50 firmware or custom firmware.

hi Slap, i think you need to go up to 3.80m33 first and then just use network update to get to 4.01M33.

it has been a while since I looked at my PSP, I still have 3.40 OE-A, what route do I have to take to upgrade to the latest firmware and where can I find the files I need? btw, I have the thick psp not the slim

Any HELP is greatly appreciated
