As you see, my post didn't affect your contest. Because OP just posted and run. :D

Yes. I win.
Trust me, bad idea.

Prepare for a speech about non-ternary genders.

Thanks I'll check it :)
But does it work with old\new 2d\3d games?

Well thanks for all the replies fellas.

If one of the posts here answered your question or otherwise helped you, be sure to mark it as the solution (which will mark the topic as "Solved"). : )

There were a few instances where it didn't pick up the image, but it worked with most games I've tried.
For example, I was successful in screencapping Dosbox (might change depending on the renderer used), ScummVM, Leisure Suit Larry 7, Brütal Legend, Red Eclipse, Blood 2 and Unreal.
