installing copied game with Daemon on psp

[Gaius]

Hello,

I have a copied version of GTA Liberty City Stories on disc which I'm supposed to copy to my memorystick, but I can't seem to be able to get it to work.

There are several folders on the disc:

ISO
MPHGameloader
PSP
UMDEMULATOR

When I copy everything to the stick I do get 2 icons when opening the stick:

GTA: Liberty City Stories - MKX
Daemon Tools PSP

Though when trying to run the game (by clicking on the GTA: Liberty City Stories - MKX icon) the psp jams.

When opening the Daemon tools psp and clicking on GTA.ISO the psp jams also.

Can anybody help?

Thx!
