This is a modified "UoDemo.exe" with the following patches appied:
  - using "UoDemo+.dat" instead of "UoDemo.dat".
  - reading directly from "..\.rundir" if file is not found in the .DAT file
  - added an environment variable DATFILE which allows you to specify which .DAT to use (default is UoDemo+.dat)
  - added an environment variable RUNDIR that allows you to overrided the ".rundir" subdirectory
  - replaced the version string with UoDemo+ and update the publish identifier
  - re-organized FUNC_4283E4_ExtractScriptBytes to allow for easier debugging (and optional code insertion)

Greetings.
