Hi there,
<<<< click on THUGPro tab on the left side of thpsx.com
Then at the top of the new page click on "Community Skaters" ^^^^^^
Those are all the user uploaded CAS. All you have to do is click the Download link next to the one you want to try.
Put the new CAS downloaded file into the "\thugpro\save" folder. (right click on the THUGPro program and click "Open File Location" to easily find the save folder)
Boot up thugpro and load the new skater.
