Hi there!! There was literally no space available within a segment to patch what was needed so a sacrifice had to be made. This file will NOT play Adlib music because, well, let's say i NOPped the AdLib function to make space for the Tandy patch. So basically when you want to play with Tandy use this patched file, and when you want to play with AdLib use the original. So yes, it is very much recommended you just copy this file as is without renaming it and keep the original LORE.EXE . Enjoy!! Yours truly, CarlosTex
