Hi !
I wrote a simple plugin that makes some changes to how the game window is controlled in MZ:
1. The upscaling mode is set to pixellated instead of smooth (or whatever the default is) to make your game upscale sharper
2. The player can no longer resize the window , this preserves the pixel aspect ratio of your game
3. Fullscreen now ONLY upscales to the closest multiple of your game's native resolution rather than just stretching it out to fit the screen , this also preserves the pixel aspect ratio of your game
A quick demo of points 1 and 3 , Fullscreen without the plugin:
Fullscreen with the plugin:
As you can see it's a lot sharper now . This is similar to how OMORI upscales the game (and undertale too I think) so if you want that functionality then this plugin is good for that !
