Hi i have firm 3.71 m33-2 do i need a 1.50 kernel to run the gpsp emulator ? :O bcause i'm having trouble when i want to run this emulator it doesnt start it gives an error oh and btw i have psp fat =P

Yup. You need to download a 1.50 eboot found here=http://www.psp-hacks.com/file/4 and heres the 1.50 addon=http://www.psp-hacks.com/file/1291

if i update to the 3.90 version i dont need to download this kernel rigt?

You need to download the kernel addon for 3.90M33.

Well i've downloaded both kernels but when i put the 1.50 kernall in a map that i called UPDATE and want to start it on my psp it says this update isnt needed because i'm on 3.71 :S is it possible that i already have this kernel when my friend downgraded my psp with pandora ? or did i do something wrong ? :O
