This release features all the last improvements of Luma3DS and also includes a brand new plugin system.
This plugin system loads .3gx plugin files.
The plugins can be placed at 2 possibles locations:
sd:/luma/plugins/<TITLEID>/<filename>.3gxto set a plugin for a specified title (higher priority)
sd:/luma/plugins/default.3gxto set a plugin which would be loaded for all games (lower priority)
Default plugin is only loaded if no specific plugin is found.
An api is available to allow you to create your own plugins using a menu easily.
An example is available here.
