I think this guy did something similar:The upscaling for the gallery is easy, and I could release that now.
However, the game itself was originally made for 640x480 screens, so it's much smaller. To make the game more playable, I need to write a script that will zoom in on the game since it appears too small on a 1920x1080 screen.
The gallery works fine since the images have been upscaled to 1920x1080, but the game assets can’t be upscaled due to engine limitations.

Also pardon my ignorance, but would playing the game on the original resolution and then full-screening it during the scenes keep the CGs in uncompressed 1920x1080?
