This page details platform, regional and update differences to the game. For specific chapter differences, please visit their respective pages.
Platform Differences#
Borders#
Similarly to the console release of Undertale, the console release of Deltarune includes various dynamic borders that the game switches between Super Game Boy style, such as a generic black border, an autumnal border for the Light World, and a castle-themed border for Castle Town and the Card Kingdom. All three of these borders are used across all chapters on consoles. All the code for the borders is still present in the PC version of the game and can be re-enabled with little hacking, but the graphics were deleted, resulting in them always appearing as pitch black.

Loading Screen#
In console versions of Deltarune, there is a loading screen for each chapter, showing the Annoying Dog hanging from a rope. The original sprite in Undertale only turns 180 degrees, while this version turns a full 360 degrees. Due to the PC version having almost instantaneous load times, it is disabled in the code. Despite that, the sprite and code for it still remain in the files. Below is an example of how it looks on PC:
