The Galaxy Level Engine is a low level engine for making SMG2 mods with. It provides a ton of functionality that you would otherwise not have.
The latest version is GLE-V3 (Patch 1)
For downloads, please visit the Releases page. On that page, you can download:
There is also a Setup Guide in the Wiki.
Most things in the GLE are documented on the Wiki, so if you get stuck it is reccomended that you read through it.
If you would like to suggest a feature, please open a Feature Request
Alternatively, if you discover a bug, experience a Crash, or experience a Freeze, report it by opening a Bug Report
Note: The difference between a Crash and a Freeze is that with a Crash you will have the Crash Debugger appear (it's a black box with a bunch of numbers and text on it). Freezes do not have this, and are often caused when the game cannot find a certain file on the disk or your SD Card.
Make sure you read the Wiki first, as you will be able to find most information there.
If that still doesn't help, feel free to ask for help in the Discussions, just make sure you use the Q&A category. I'll answer as soon as I can.
