Also, the random values in the 40x25 matrix is because we don't know how to interpret FOG.TXT due to a complicated algorithm and/or self-modifying assembly?

Finished the linear texture sampling code and I got this which looks promising. I had to convert the gradient calculation to true color for this example. Note the empty 9th...

I'm so close to being convinced that Arena uses some kind of spherical projection to map the fog onto the screen. If you turn the camera then the fog shimmers;...

I just made one small discovery -- the right edge of the screen has a blocky appearance to it, like the 320x200 texture is not getting populated correctly from the...

How do I use the low 8 bits of each FOG.TXT sample to do the dithering? I tried adding it as a delta but that just makes everything brighter and...

This is where I'm at. I tried the every-second-pixel pattern but not the movement yet. 

Going to try passing this data to the renderer next but still don't feel like I understand everything completely.

I'm thinking of merging what I have now to master and coming back to it later once we have more information on how it all works. I want to get...

I might be misunderstanding the problem and this is just how it would be due to beat frequencies or something? Anyway, changing it to this seems to have no change:...

Yeah, I was about to suggest that. Having the save file format in the wiki would be preferable for long-term records. We can keep this issue here as a reminder.
