Hey, I created QuetzaDrake as a sim for The Sims 2. The meshes i got from modthesims.info, although the ears and tail were originally 2 separate accessories, and the sims 2 has no way of combining 2 accessories into one. I had to actually do it myself by extracting the meshes with SimPE (a modding tool for The Sims 2 that allows you to mod pretty much every aspect of the game) put them together in milkshape3d (a 3d modeling tool for modding) then re-import it with SimPE and then create a clone of an accessory then link that to the mesh, also when i put the mesh together i had to extract the joints and assign the meshes to the ones they need to to get the accessory working right. The skin tone is a modified skin tone i got from modthesims.info, basically what i did was change the color of it in Photoshop, i used the same texture for the ears and tail.
here's the link to the installer (created it using Nullsoft Scriptable Install System, great alternative to commercial and proprietary products like InstallShield)
