GOG version of DCOTE

It looks like the GOG version of DCOTE has fixed shaders for the blue light problem.
I've checked and they match the ones from here:

There are also changes to the main exe but nothing in the xml area.

Well that went well

Luckily the textures in the .pc.naf files are all at the end of the file.
They are in a format of texture id, texture length, texture, asterix which is easy to split out and rebuild. I just saved the unknown chunk of data before that into a file and then each texture split out into its own file.

I tried a simple test of the main Arkham plack by increasing the texture size from 512 to 1024 and this is what I got.

So at least a full high resolution version of the game would be possible now if anyone has the time and inclination!

Well this is promising

A quick look through a .pc.naf file shows that where the "DDS" file format marker is for each texture immediately before it is a 32 bit number which is the length of the texture.
This means I may be able to simply split the file up into texture and non-texture chunks and then rebuild with different sized texture chunks and have it all just work.
More than likely though there are other length values or pointers to elsewhere in the file that would need rewriting but at least I have somewhere to start.
