Like Mario, Luigi has three LOD models, being the high-poly, medium-poly, and low-poly variants. The high and medium-poly models have textures applied and are in a mostly complete state, with a few exceptions such as floating during certain animations and having crooked right hands, while the low-poly model is completely untextured and by far the most broken and unfinished of the three. Luigi features unique textures for his mustache, sideburns, and hat emblem, but reuses Mario's eye and button textures. luigi.c--the file containing his texture and armature data--is also dated June 20, 1995, which indicates that he's based on an even older version of Mario than the one found in Mario_old/old.
