No, I tend to leave the maps and a bit of programming stuff from the previous games in in case I need to reference them for whatever reason, though I've stripped a lot of that out working on 3 now for practical reasons. But the entirety of the first game, in terms of maps and a lot of code is in the second for that purpose. They take up almost no space, and I was under the mistaken belief that I couldn't have two copies of RPGMaker open at the same time for a while, so I thought that was what I was stuck with if I wanted to check old work or reuse some of it.
Long story short though no, none of that old CS1 stuff in GT is used, it was just there as a reference bucket for me (though there IS obviously one boar scene in GT, in the alley early on).
Glad to hear you're working on a translation though! What language are you working with? There's already one in Japanese and Chinese, and one in Spanish has been underway for a while, though I'm unsure of the progress there.
