I'm sorry, but if I wanted to play such a game, I'd use FreeSCI. Honestly. No need to waste time and efforts. It's the same, no, it's even worse, because these particular vector graphics were made for 320x200. My advice - optimize it. Even though it's re-rendered in 640x400, it's still blocky and doesn't make any sense. Load Photoshop up, do some pixel-editing. Or just make plain SQ3 Point and Click a la Larry 2 remake, without any graphical changes. Because it's stupid to do only the half of the job.
