Yes, and yes. The first DLL, resources.dll, goes from 0 to 65536 - which is everything from 1 to 5 characters in length. Similarly, the more DLL's you add the higher the IDS will become, so the 50th DLL would have IDS values with about 9 or 10 digits.

Not sure I understand the importance of having different length numbers though, they do the same thing whatever length they are...

O I never really knew that and was wondering. Yup I know a noob question. ^^

To my knowledge, Freelancer will only recognize 9 dll's. The game comes with 6, so you can only add three more, unless someone changes something I don't know how to change... perhaps in the exe file or something.

If you know any more about this please post.
