Mashers's Grid Launcher Updater 3DS

From GameBrew

mashers's gl updater
Last Updated2015/12/08

This is a homebrew program that downloads the latest version of mashers's Homebrew Launcher with grid layout.

It uses a modified Lua Player Plus by Rinnegatamante, removing non-essential features to greatly reduce filesize. It is based on this commit. The source of this is contained at extra/ Please see the original repository for technical details.


This updater can be added to the grid launcher's settings menu by placing mglupdate.3dsx and index.lua in /gridlauncher/update/.

Otherwise, extract it any place you like (e.g. /3ds/mglupdate/).

If you are setting up a custom updater, the enable folder in the site should be password protected.
