Text binner worked like a charm; it converted basic sins + entrenchment in around 5 minutes.
(On a side note I fail to understand why a copy of the latest game info files preconverted to text. aren't included with each update of the forge tools. They come to barely 3 mb togther, less then a converter file almost.)
Now I have these files I'll be making some more mods, and rereleasing my earlier versions.
