I've decided to supply a direct link to the skin after waiting weeks for approval.
LINK FOR JOKER SKIN:
Right click and save image as, then place it in your skins folder and follow the below instructions. Just be sure to use this skin only with the Taxi Driver player.dff, it won't work with Claude's (the original player.dff) player model.
A Joker mod for GTA III. I've taken different Joker skins, edited and compiled them into one image and added the skin to work with the Taxi Driver DFF model created by gtadude1, which I do not take credit for. That is his model that he created, and it is awesome. Fully recommend it.
Download the skin from the link provided above
Place the image file in your skins folder
Download Taxi Driver player model by gtadude1 here
Open gta3.img from the models folder in your GTA3 directory in imgtool
Export player.dff and save anywhere as a backup, then delete it from gta3.img in imgtool
Add the player.dff from the "Normal Hair" folder included in gtadude1's Taxi Driver mod
Go to Options > Player Settings, then choose the Joker skin
Enjoy, and please rate!
