I have received complaints as to the requirement of MSTSbin to use KLW stock, of which some of these individuals argue that KLW stock should be produced for users of both BIN and otherwise.
Personally, I believe that the advent of MSTSbin has since set a new standard exceeding that of the original game. For that reason, I try to utilize all possible advancements the new "foundation" BIN provides in each of the latest KLW releases.
Nevertheless, I realize that some of you prefer to run without BIN, and I respect that decision. However, MSTS creation still remains a time-limited hobby of mine, and I cannot possibly provide KLW addons in multiple formats that can effectively please everyone.
That said, KLW addons will continue to be produced with compatibility for MSTSbin, even if it compromises compatibility with the pre-BIN versions of MSTS.
Regardless, KLW addons are not wholly restricted to BIN users. As with all MSTS addons, users can easily retrofit the latest KLW addons to work properly in non-BIN versions of MSTS, usually with little more then adjustment to .eng or .wag file lighting parameters.
