I2N2GPL.EXE

This WIN95 program will convert tracks from ICR2/CART and N2 
to GPL.

To convert make sure you have correctly set the directories for 
CART/ICR2 (or N2) and GPL. 
You should be entering the application directories 
(e.g c:\sierra\nr1999 and c:\sierra\gpl and NOT the track directories).

If the source application directory is correctly set then you will see 
a list of tracks to choose from. Select a track and hit the convert button.
You will get an error message if the incorrect GPL directory 
has been set or you run out of disk space.

If the conversion is a success then the GPL season files are updated 
and you should see the new tracks in GPL.

The converter has been tested with Nascar 1999 and ICR2. I have no reason 
to believe there will be problems with either other N2 versions or CART.

The intention of the converter is to provide new tracks to race at. 
I have not attempted to create 1967 graphics or versions of the tracks.
You may not believe it, but a vast amount of work has gone into the AI!.
I have tried to make the AI drive at good racing speeds and take reasonable 
lines. However, it is simply not possible to get the AI as good as that 
created by Papyrus.


Known Problems

Note that some of the tracks have the pit wall removed this is because of 
graphic problems in these sections of track caused by polygons laid 
underneath the pit wall in the CART or Nascar version. 

When the Pit lane is to the left many cars do not make it out to practice.
I assume that this is due to the fact that the default tracks never 
have a left side pit lane so the logic to ensure all cars practice from 
the left was never checked in GPL.

Some of the graphics look very stretched.  This is due to complicated 
compatibility problems with textures of all sorts of resolutions and 
colour depths. GPL has its own restrictions on the type of textures 
it can display correctly and this has lead to compromises in the texture 
conversions.

Finally

Many, many thanks to Alison Hine for all her help with this project!.
