I am Raygoza and keep contact with mod developers of mods I like, I like to help my offering suggestion and ideas. When it comes to modding I am not good at it, I am only able to change a few things in StarCraft and Homeworld 2.
Some mods for Homeworld 2 end up with their text references in Homeworld 2 Classic for several things like descriptions ingame. This is original HW2's English.big file which seems to work flawlessly on Homeworld 2 Classic on steam. I haven't experienced any problems using this with Homeworld 2 Classic.
The race selector of Homeworld 2 Classic has Taiidan and Kushan race option names, I wonder what other things remain from the development of Remastered.
With references that appear when I play PTV on HW2C is $1102 or some other numbers as you can see in the image, but happens for me in names and descriptions for ships and research projects unless I replace the English file with this one.
