Hi guys Im looking into getting a couple different Developer systems however I need some help. A while back I was looking at a message board about a cancelled game and a developer from that game just so happened to pop on and post a picture of the game. The quality was superb and there was no artifacts from capturing. I messaged him asking him how he got such a high quality picture. He replied that he took the picture from the "Frame Buffer" of the system with his developer console.

Now this is my question, Do the following dev systems have this ability, and if so how far does it go? Can I capture video from the game directly instead of going through s-video, etc?

DC Katana
PS2 Tool
Dolphin (large case one, not sure of the name here)

If these cannot, then how did this developer do such a thing?
