white car textures on schroeder and Nicola Acciarri cars

hello, raztahz here...

i know this was asked before

i just downloaded schroeder and Nicola Acciarri f1 2002 and 2003 textures and carshapes

however i have some problems installing them into gp4

i'm using the official patch for gp4 and it is restricting me to use gp4 master that uses v1.00

i tried using wad.updater , installing them(with their downloaded .tex names) . renaming the files to overright the original textures... but eveytime i play i get white textures on the cars

i've usesd Bojan Tarticchio's williams f1 2003 which seems to work

can anyone help?

i' currently using the low textures (800x600 res) to get optimum fps
which is great for people using low textures

problem is that their textures have different names to those in default cars.wad therefor wad updater will not work. need to use gpmaster, there was an update to make it work with 1.2, however its not needed, just put a copy of the decrypted ver 1.oo gpx.exe in your directory and name it gp4old.exe then point gpmaster to this exe and it will work fine.
