Team SpiderGX released a new PC tool that will allow to have customized text (language) in the upcoming release of SpiderGX OS:

This new software comes along with a new version of our SpiderOS that has Multilanguage support.
The SpiderGX Customizer allows you to modify text in the SpiderOS menus. It will create a file that is recognized by the SpiderGX chip and it will be loaded thanks to the SpiderGX WebOS.
The file "french.gx" is already available and allows you to change your SpiderGX OS menus in French. Other languages will be supported shortly. If you create your own files, you can send them to Team SpiderGX so we will add them on our website http://www.spidergx.com.

Note: The new SpiderGX OS v1.12a that will load these .gx files is currently in final testing and will probably be released today (Friday).
