A collection of utility scripts for Drop instances, specializing in handling multi-part RAR archives and ISO mounting.

Extracts RAR files, mounts ISO images, and runs executables.

Files:

• extract-mount-run.bat - Main extraction and execution script
• exr-setup.bat - Game setup launcher for multi-part archives
• install-user.bat - User installation/setup script

I updated this to add support for multi-part GOG installers, inno-setup directory matching the Drop install folder, and adding an executable as a startup item.

Simply add:

• Setup item: exr-setup.bat
• Run item: drop-start.bat

1. In your Drop instance, navigate to Executors or Add Executor
2. Create a new executor pointing to the Drop-Scripts directory
3. Set the executor name (e.g., "DropScripts" or "extract-mount-run")
4. Confirm the path points to your Drop-Scripts installation

1. In your Drop instance, create a new Version

2. Configure the version as follows:

   Setting	Value
   Setup Configuration	Windows: install-user.bat
   Launch Configuration	Setup-only mode (no launch config)

3. This version handles basic RAR extraction and ISO mounting with EXE selection

For games distributed as multi-part RAR archives with ISO files, create an additional version:

1. Create a new Version

2. Configure the version as follows:

   Setting	Value
   Setup Configuration	Windows: exr-setup.bat
   Launch Configuration	Windows: drop-start.bat

3. This version uses the enhanced launcher optimized for multi-part archives

Use the extract-mount-run version:

• Drop will execute install-user.bat during setup
• The script will prompt you to select a RAR file and executable
• Alternatively, pass RAR and EXE parameters directly:

  extract-mount-run.bat "path\to\archive.rar" "setup.exe"

Use the extract-mount-run-multipart version:

• Drop will execute exr-setup.bat during setup
• This handles multi-part RAR archives (.rar, .r00, .r01, etc.)
• The script automatically finds and extracts the main RAR file
• Locates and mounts ISO files from the extracted contents
• Executes the selected or specified EXE file

• 7-Zip: Must be installed at one of these paths:

  • C:\Program Files\7-Zip\7z.exe
  • C:\Program Files (x86)\7-Zip\7z.exe

  Download 7-Zip

• Windows PowerShell: For ISO mounting/unmounting operations (included with Windows)

• Administrator Rights: Required for mounting ISO disk images

• Windows OS: Scripts are designed for Windows systems

1. Extraction Phase:

   • Script searches for RAR files in the current directory
   • Creates a temporary working directory
   • Uses 7-Zip to extract the RAR archive(s)

2. Discovery Phase:

   • Searches for ISO files in the extracted contents
   • Lists available executables on the mounted ISO
   • Prompts user to select an executable (if not specified)

3. Mount & Execute Phase:

   • Mounts the ISO using PowerShell's Mount-DiskImage cmdlet
   • Executes the selected EXE file
   • Returns the executable's exit code

4. Cleanup Phase:

   • Unmounts the ISO image
   • Removes all temporary extraction files
   • Closes the command window

• extract-mount-run.bat: Core script handling RAR extraction, ISO mounting, and EXE execution
• setup.bat: Simple launcher that spawns a new cmd window and runs extract-mount-run.bat
• exr-setup.bat: Enhanced launcher specifically designed for multi-part archives
• install-user.bat: User installation/setup helper script

Version Name: extract-mount-run
Setup Config: install-user.bat
Launch Config: None (Setup-only)

Version Name: extract-mount-run-multipart
Setup Config: exr-setup.bat
Launch Config: None (Setup-only)

Both versions run in setup-only mode, handling extraction and execution during the installation phase without separate launch configurations.
