LOL I did that to make a gif a long time ago. I took the Seikendensetsu 3 Angela and moved her frame by frame in game and copy / pasted screenshots. then I cropped out the entire background then chose the frames I wanted, placed them together, smoothed the pixels, colorized it, and made it into my Vierna character walking.Technically I could take screenshots on an emulator but then I'd have to beat the game several times, each time with more treasure...
...*sigh* I'm on it :/
