Mario Kart 8 Deluxe (MK8D) is a flagship racing title for the Nintendo Switch. As of the latest official patch notes from Nintendo (covering the Booster Course Pass wave 6), the current official version is 3.0.1 (or 3.0.2 for minor stability fixes, depending on region). There is no official Nintendo-sanctioned “Update 3.0.3.”
The terms “NSP” (Nintendo Submission Package) and “XRAR” (a misspelling or variant of XCI or a scene release tag) are file formats associated with unauthorized (pirated) copies of Switch software. Therefore, references to “Update 3.0.3 NSP/XRAR exclusive” refer exclusively to custom/modified/pirated content, not an official retail update.
