Legacy Console Pack Editor

A small WinForms tool for browsing and editing .arc (.swf) and .pck packages used in legacy Minecraft console editions.

What it does

• Open .arc archives and browse their contents
• Open and edit embedded .pck assets (extract / replace / delete)
• Open .swf files from .arc and edit them via an external editor (auto-sync back into the archive)
• Preview and edit image assets

📦 Using the installer (Recommended)

Head to the releases and download the prebuilt installer!

Requirements

• Windows 10+
• .NET 8 runtime (or .NET 8 SDK to build)
• Java 8+ (only required if you want to edit SWF in the embedded SWF editor)

The app will automatically locate it and use it when you choose Edit SWF.

Building from source

From a PowerShell prompt in this folder:

dotnet build -c Release

After building and adding the needed files, run the executable under:

bin\\Release\\net8.0-windows\\LegacyConsolePackEditor.exe

TODO

• Add an app icon
• Make the .loc file editing work correctly with safeguards
• Revamp the UI to make it feel comfortable to use
• In-app .swf editor
• Download a pre-made example pack
• Animation viewer
• Maybe a web app?
• In-app .png editor
• Open folders
• Basic Hex editor
• Beginner/Baby mode with basic file names etc...

Special thanks:

• PCK Studio's source code to understnad .pck editing
• Jpexs decompiler's source the the painful .swf editing
