I was messing with the FE3 modules that came with nightmare, and decided to translate the old names. Here it is, fully translated (I might have missed a few, tell me if this is the case). I also figured out what the unknown byte in the class bases editor is (weapon level) and how item range works. Thanks to Camus for the original modules and mysticShadow for helping me research how range works.
Update: We now have shop editors! You can now change the items that shops have.
