From the blog "Sith Holocron's Blog"

Originally, I cribbed the original form of this list from the internet.  However, after I made the The TSL Warp Code List, I knew I would have to make a list for the KotOR1 warp codes.  I already had the BOS:SR codes but realized that the list would be compiled much faster with the community’s help. This list and the TSL list, are living lists: if new codes are found (or introduced by way of new mods), they can be added.  As with the TSL list, new codes will be attributed in the main post.
