This script automatically updates your custom system files each time ES-DE starts.
Installation Instructions
- Place 
update_custom_systems.shin~ES-DE/scripts/startup.
(Create thestartupfolder if it doesn’t exist.) - Open ES-DE and navigate to Main Menu > Other Settings > Enable Custom Event Scripts, then toggle it ON.
 
How It Works
- On ES-DE startup, the script will download the latest custom system files from the GitHub repository and save them to the ~ES-DE/custom_systems folder.
 - Existing custom system files will be backed up to 
~ES-DE/custom_systems/backup.
(The last 5 backups are retained.)
