I need help using Duke Nukem 3d on my PSP. I tried both eboots, the smaller one from the Duke3D folder had the icon etc, but when I tried to run it said it could not run. The bigger eboot from the Duke3D% folder came up as corrupt! I've got the grp file in the same folder as the eboot. Got both folders under the game folder with the grp file in the Duke3d folder, still no dice.
