Most of the tools that were released are very well detailed if you take the time to look through the files provided. I have found out so much information from going through the files and taking the time to read what has been provided.
If you really want to go forward with a Zero Online server, You need to put in the effort to actually learn and everything that has been provided, Is more than enough information - If you cannot work out a work around to the .exe before locating the Worlds.dat then I'm sorry but you may have further issues trying to understand the more complicated side of editing stuff.
Thank you again Soulless for this! You are truly a legend and i'm sorry if you are getting spammed asking for help due to this release, You don't deserve that at all!
