replace player.dff and player.txd in gta3.img
replace player.bmp in \models\generic\
-jacob"
So, you have to got to your models folder, go to the generic folder, backup your player.bmp, then replace it with the mod.
The 2nd one, you'll need IMG Tool, open up the gta3.img and find the player.dff and click on replace, then click on the mod player.dff and just click close.
what do you mean y backup your player file???
I think he means back-up your default Player Skin. It is recommended that you do back it up. Make a new folder in your Rockstar Games folder called "Backup" and put the skins folder in there with only the original Skin File in there. The default skin is the Greenish Blue Hawaiian/Palm Tree shirt with jeans.
what happends if you got rid of it a while ago ... with no back-up
