This gallery showcases possible methods of remastering Toonstruck and Toonstruck 2. Check it out, and then let us know what you think in the comments.
Comparisons
In the two examples below, the assets have been completely redrawn. This is a time-consuming process, considering the 60+ backgrounds in the original Toonstruck alone.
In the above example, a still from one of the game FMV sequences has been given the AI treatment.
In the following examples, AI-upscaling has been used to increase the resolution of the backgrounds. The results can vary; however, they are generally very good, considering they were created using 640×480 screenshots (rather than the original game assets), and the AI was trained on a generic model rather than a similar art style.
It is, therefore, very conceivable that AI could be used to dramatically reduce the time it would take to remaster Toonstruck in an HD format. Of course, the sides of the images would still need to be drawn to enable a 16:9 format.
Toonstruck 2 Gallery
Here are some images from the unreleased Toonstruck 2 with AI upscaling. The size and quality of the original images is generally very poor, so the upscaling has not been as effective as the upscaling on Toonstruck 1.
