im kinda new to this and have only ripped some textures from lsw3 psp and lego indiana jones 2 psp. if anyone is willing to help me out that would be gratefully apprecitated. im wanting to rip and recreate killer frosts texture from lb2 ds / 3ds as she appears only in those versions (unless you count the moblie ports of it).
