WARP.DLL QUESTION

OK, so i picked up this game and while i Was a it I inserted of the DLLls inside the package into my main RM2k3 file as well. I noted the game had a version of "Warp.Dll>" that was 25 KB and mine had a version that was 28 kb, copied from Forever's end methinks.. I'll admit I decided to drop in the new one and replace the old one , but was wondering if anyone had any clue why there might have been a difference in size and whether it had any perks, in which case i suppose i should grab it again.
