Introduction
The VERsion packet contains information about the LFS and InSim versions, allowing you to prevent your program interacting with legacy versions of the game. To request an IS_VER packet, either set ReqI to non-zero in the IS_ISI packet when initialising InSim, or send an IS_TINY packet with a SubT of TINY_VER.
