you guys wanted it so im giving it to you, i moded this lamecraft version so it looks like the netherworld.simply load the pre-made map in the load section.
i cant take credit for this lamecraft version, for i only moded Lamecraft nnm mod v1.3. i made it look like the netheworlds, by modding the normal terrain, so dont be expecting any grass,water,gravel and trees.
to install, simply download the fill, open the rar. file and drag the folder(nethercraft) in your psp, into your game section.
