shipnames.txt and strings.txt

These 2 files are not absolutely necessary for the proper function of this shiplist. BUT, they get rid of all those pesky '???' you might encounter. I even cleaned up the missing data the OP shiplist itself has through some patience and a lot of free time. A lot of work went to make sure these were accurate.

I strongly recommend using these files.. as they just improve the look and feel of the game.
NOTE: the installer introduced as of version 2.2 takes care of all installation problems.

model.siz

This file controls the size of models included in the OP+ Project packages (as of version 3.0). Its use is as important as the other supporting files.
