+++++ IMPORTANT +++++

Voodoo graphics card users need to download the special version of this patch for GLIDE.


* Other Information *

I have based my patch mainly on the video of the 1967 season, "Nine Days in Summer", supplemented for detail by photo's from the '67 GP.

All textures in the patch are 4-bit.  The only textures which have increased in size are the single-spectators to allow them to be replaced by groups of 2-4 spectators, and one advert.  The new cross-track banner texture is the only texture that exceeds 256 pixels in length and a lower resolution version is available for those using Voodoo graphics cards.

* Changes Included *

Adverts - the patch includes adverts for pits, grandstand and around the track which are more representative of 1967.  The limitations of the original track mean the variety and placement of adverts around the track is not particularly authentic.

Tower and Banner - the tower has been edited to improve its authenticity.  It is repositioned nearer to the track, is taller and narrower and includes the cross-track banner.  Although the banner is authentic, it is not torn as the original was at the end of the race.  Keeping the banner symmetrical was essential to keep the editing relatively straightforward.  As it was, the editing required was a major leap in my 3do editing skills!  For the same reason I have not produced a "split" banner to allow Voodoo users to use the high resolution texture.

Spectators - all the original GPL tracks have insufficient spectators and Mexico City seems particularly sparse, perhaps because there is only one proper grandstand.  I am not able to add spectators where there were none before, but I have replaced individual spectators with groups of 2-4 people, and also included a few soldiers (who were given the job of crowd control).

Track Textures - the original track textures had outer sections lighter than the central section.  Film of the 67 GP shows most of the outer sections were darker than the central section, with parts that were the same shade. My replacement textures use darker outer sections.

Other changes - I have made the red, blue and white houses a little taller, edited their textures and put more spectators on the roof. I have always been wary of editing grass textures as the grass colour varied around the track and is subject to variations in film processing/ageing.  However, I have changed the shade of the grass a little.

Changes NOT included -  I have not included a new sky texture because the Papyrus original (though not inspiring) is a very good match for the sky in "Nine Days in Summer".  Photos of the 1968 GP show a similar hazy blue sky.  The finish line chequers and MEXICO '67 graphic are the wrong way round and in the wrong place, but it was not possible to alter this.

* Options * (or I want my old Mexico back!)

When I have driven round a circuit for hours, I find I do get attached to the original Papyrus textures, particularly tarmac and to a lesser extent grass.  If you want your old tarmac back, delete the following files: -

tarmac.mip, concrete.mip, paintasp.mip and fixasp.mip

If you want your old grass back, delete the following files: -

grass.mip and horiz.3do

* Changes in Version 1.1 *

Changes in version 1.1 are to improve the quality of the textures and to improve historical accuracy.  They are the result of me finding a new source of period photos.

Included are:

- a higher resolution yellow PEMEX advert (the text is now readable),
- the white Goodyear banner is replaced by a yellow banner,
- the Pepsi signs now have red at the top and blue at the bottom,
- the META banner has a few more holes in it, and
- the grandstand ads have been changed.
