Another user, called icemanoob, showed in a video how he films his gameplays (they have a good quality, just like GSD's). I don't know wath he exactly did, but his 3DS has some hardware changes that allows it to be connected by USB to the computer. And, once the gameplay is shown on the computer's screen, he can record it with one of these typical screen recording softwares. I'm sure that GSD uses the same/similar sistem.

Also, if anyone here already has a japanese 3DS and a copy of MH3G, he/she can use that system to get some good quality pics of equipment for the wiki. But since it's risky change a console's hardware, you should be really careful...
