A couple of upscales of the legendary The Secret of Monkey Island. While some of these turned out great, I do think there is some room for improvement. For starters, these all are based on images I found online, so they weren't uncompressed screen captures I took myself. Perhaps for the best possible end result, it would be best to actually rip the uncompressed images as they are directly from the game data itself.
But, overall, the results are pretty decent. They definitely look better than what the official HD remake of the game looks like. So, with some elbow grease, a fan-made HD upscale that actually looks good could be achieved. Some screens could probably do for some retouching in a painting app, but it does speed things over from painting everything from scratch.
