The 1024x1024 texture of the wheel strip includes multiples of 5, from 00 to 100, with few repeats and 01. The edge scheme includes dollar signs, and the wheel strip has colored emphasis on high scores 100 and 95, as well as other scores. This texture map can easily be edited in Photoshop or any similar program. Change the numbers, then open your 3D program and reload the texture.
The original file is modeled, textured, and animated in 3dsmax 2009. It is also imported, textured, and animated in Maya 2010. I exported it to other file formats, and the model & texture data should work.
