Sometimes Finnish "sisu" pays off. I finally sussed how GP4 works...well at least I finally got it to work for me. I installed a Mclaren Steering wheel
I followed the instructions extracing Cars.wad to a separate folder. Then in tex workshop loaded each of the relevant tex files from the cockpit folder (in that new separate folder). Then I clicked "replace selected file" and retrieved the relevant Mclaren TGA file. I clicked "downsample" to change the smaller versions also and then "save tex file". Did the same with the rest of the steerig wheel files.
Ok then back to WAD-workshop: "create wad file from directory". I typed in the address of the temporary folder. The it asks for wad name, I typed in "cars.wad".
What GP4Master then does is to create IN THE GP4 FOLDER a new cars.wad file. I backed up the cars.wad file from the game and copied and pasted the new cars.wad from the GP4 directory. And hey presto! I think GP4Master can export this wad file automatically, but it has never happened for me. Whatya think?
