GECK Extender
The GECK Extender is a project to extend the functionality and fix bugs
in the Garden of Eden Creation Kit for Fallout: New Vegas


Download a fresh GECK from either steam or geckwiki.com
Replace GECK.exe with the provided one (this is now required)
Install the extender plugin


Install with an appropriate mod manager or manually move the NVSE folder in to your Data folder.
Remove any previous version of GECK Extender (GaryHax.dll).
Remove any version of GECK Power UP you may have installed.

Compatible with all NVSE script extender plugins.
Do NOT use with GECK Power Up or GECK Power Up Fork. GECK Extender supersedes them.

Note: The marker hack has not been recreated, this was fixed in the official GECK.
