As the title says

There should be since 1.2.6, but I've no idea what the shortcut is. Try F12 I'd say.

That was the first thing I tried, if a sceenshot was taken, nothing notified me of it.

Does it make a difference if I play it as a desktop shortcut? Maybe I have to play it within Galaxy itself?

Edit: Okay, I experimented

--It is F12

--Doesn't work with Dosbox games on shortcut or through Galaxy

--The games it does work with, can only be taken if played through Galaxy, not a shortcut.

FRAPS?

Yeah, FRAPS.

I believe the freebie version has all the features you'll need for your screencap enjoyment. I'm not sure if it works on DOSBox games though.

Yea you must use Galaxy and the overlay must work in said game (as far as I know).

Personally I find it just easier to press "Print Screen" and save it to a paint file.:) thanks guys ^^

If you're interested in an alternative, I suggest looking for a small free program called Cropper, it can automatically save a png or jpg file as you press the Print Screen button.

Probably will be for a while, one has to remember this feature is brand new... as more games are made compatible with the overlay and some bugs are ironed out. It will become much more useful.
