Hi guys, Just wanted to asked a question regarding driver development. I am in the process of studying c++ not because i want to write drivers but because i always wanted to learn c . I know drivers are developed using lua specifically and really great things this came come from it. But my real qusetion is, is it really worth writing drivers if there are so many drivers out there for free as well as for sale? Is it worth the time and effort? Any advise would be greatful...
