This is how I do it, I don't if my way is the best way, But what I do is run the rom in an emulator called DeSmuME there is loads of tools that let you see certain layers and stuff. I just edit the layers so I can see the Image on its own then just Print Screen, paste in Photoshop.
Now I've had my EZ Flash for a few years now, but i'm wondering if i could set it so it will auto load a rom, so when I turn it on and it boots into the menu, it just automatically loads whichever rom I choose?
