You can either make 2 copies of your P99 folder one for Regular or you can use the batch file I created(extract to p99 folder, place shortcut on desktop) which will "patch" the version you want to play on.
If you don't have the hard drive space the batch file is simple, it will prompt you for which server you want to Patch. You just run it before you open Everquest. You can patch for Beta open everquest and then patch for blue and open another instance of everquest if you want to play on both servers at once.
