"GSLaunch" is a modding tool that im making for GSClient (the russian client from Dev-CS.ru, which adds major updates to your CS), which has an interface inspired in 7Launcher. This one, allows you to modify your installed GSClient changing to each modded version you want (like from Down-CS), the game language, and many more.
Note: i don't pretend to promote my project because i know that is not allowed here, but im just declaring this to your question to give you more information about my project if you're interested. I hope that you can understand this. Cheers.
