I tried the trainer which i downloaded years ago from this site moments ago and it still works for me. I believe the recruitment one never worked anyway, but everything else was fine. I could research items that required 20 turns in 1 turn. Movement was fine and so was building buildings. I bought the physical copy which needed steam, so i'm not sure why your one doesn't work. That being said, with this wemod thing, i wouldn't be surprised if it affects trainers in a bad way. I can't get my homeworld remastered trainer to work despite it saying "game on" when playing it.
