I created this because I wanted to make a fake "boot screen", as seen here:
You could also use it to display a logo or similar.
By default the splash screen can be skipped at any point after the Scene_Boot is ready, by pressing escape.
The splash screen is loaded as soon as possible after the database in order to permit the image to be encrypted.
If you have a huge database and need the splash to appear earlier, let me know - there's optimizations possible that seemed unnecessary when testing with a modestly sized database.
As the plugin only modifies Scene_Boot, it is unlikely to have compatibility issues with other plugins. However reordering with respect to any resource preloading plugins may affect the load order of the splash screen.
