SaveUpdate Scriptlet

ACE Version

by Kyonides Arkanthes

Introduction

There was a user that once wanted to add a very specific feature to the game header, namely the current map's name. Well, this scriptlet should let you modify all of your existing saved games by automatically adding that name to the hash for you.

Warnings

• It has no GUI at all, guys!
  
• This is a temporary scriptlet. Do not include it your official releases!
  
• Be wise and backup the game files beforehand.
  

Code:

# * SaveUpdate Scriptlet ACE * #
#  Scripter : Kyonides Arkanthes
#  2023-04-09

# This scriptlet facilitates the update of your old saved games by adding
# secondary features like Current Map's Name and the like to the header.
# It has no graphical interface at all. Not like it ever needed one, though.

# * Scriptlet Published and Distributed AS IS. * #
# I might refuse any user's request for upgrade or maintenance releases. #
