"Make games in fullscreen without changing the resolution mode, while maintaining aspect ratio. Your game can be any resolution. Widescreen games are displayed in letterbox on normal screens, and non-widescreen games are displayed with black bars on the sides. Pixels are crisp and not anti-aliased.
There are also options for pixel-perfect scaling (integer-only scale), Hor+ and Vert- widescreen, and manual control of the game rectangle."
PROBLEM IS it's for Multimedia Fusion. However, the creator uploaded the source HERE
Would it be possible to get this to work with Construct Classic? If so, is anyone interested?
