Andres has been doing a lot of work on the mod, so maybe the Version that's up for download is different from mine. And my Version has been tweaked (a few important 'standard' tech areas were made available, more troop types were created and fighter propulsion was redone).

You really only need the mod to see the tech trees so you'll know what research leads to what components. Everything runs on either standard SEIV tech or Star Wars tech straight from the movies. The exception is what I call 'pre-tech' - implosion drives and such - which you don't see in the movies but are logical steps in the technological evolution that leads to the tech seen in the original trilogy.
