Playstation Title and Snap screenshots

[George Woody]

Hi, this is my first post, but my accout is about a year (just leeching XD) and I think this is the time to contribute to the community.

I'd like to start making some screenshot (titles and snaps) but with redump renaming system.

All my isos are 7zipped uncomressped by rocketlauncher y and played by mednafen retroarch.

So my question is, what is the best way to take titles and snaps screenshots? what emulator? what's the ideal screen resolution? how can a know what's already done? and what's not? I really want to contribute, I've always been a leecher XD with a free acount, and I think I shoud retribuite in some way

I'd like to make Video snaps too....

 

Thanks
