Auto Updating my Game?

Hello all!

I know this question has already been asked, but I can't find anything good (on here, or anywhere else on the Internet).

I want a system that automatically updates the users game upon loading it, updating the entire project. This is good for info, fixes and news etc., as you know.

I know about Crafty and HegsaPatch (that might not be the name, don't fully remember). I've also heard of M2H patcher, but it isn't available anymore. Also, I can't pay for anything.

Is there a free and simple system for what I need, and if so then how would I go about doing it?

Thanks in advance!
