I was messing around with an upscaling algorithm called waifu2x. I already used it to for a texture pack for Army Men RTS (link here), so I tried to see what I can do for Machines.
Textures for the machines themselves are fine, what sticks out are low resolution terrain textures in some of the maps. Unfortunately I read here that the game has a 256x256 limit for textures, so some maps can not be updated, because textures are already at the maximum size. This is most noticeable in the training levels and Rolling Plains maps that look awful.
I did some tests on Adelphi9 (moon) textures and ice map textures. Since waifu2x algorithm smoothens everything and makes things look like a painting for the moon textures I also applied a HSV filter using Gimp to add some noise, so it has a more "sandy" look. I think it turned out quite well. Since ice is supposed to look smooth, for ice textures I applied some noise only to the parts where there are rocks visible, but it didn't make much of a difference.
You can see some comparison screenshots here. Best is to open the screenshots in a new tab to make it fullscreen, so you can see the difference more clearly.

Tell me what you think. Don't expect me to make more of these, the algorithm doesn't work well on everything, some maps can not be updated and the whole process is time consuming.
Some extra information for texture modders:
- Texture limit is 256x256 and textures must be in .bmp format.
- If you are using GIMP when you export the image in the Compatibility Options you need to check "Do not write color space information" and in the Advanced Options select "24 bits", otherwise the game will crash when loading textures.
