Main Game + Updates
This filesystem contains the base game, plus all downloadable updates for the game, which ended with v4.1. (Explanation about how the Wii U updates are applied and how we merged them here)
The base game of Mario Kart 8 has 3 different releases. Japanese (NTSC-J), American (NTSC-U), and European (PAL). All 3 base games contain identical files and filesystems (apart from app.xml, meta.xml and manual.bfma), even including language files that can never normally be used on that version. Updates, however, only included the needed language for that specific release. The file system, file sizes, and file list will be based on the Japanese release, but it can be assumed that it is the same for the other releases unless otherwise noted.

This filesystem contains the DLC content that can be purchased separately on the Nintendo eShop. (Explanation about how the DLC is applied/unlocked here)
The 3 DLC releases are all 100% identical (apart from app.xml and meta.xml). The DLC filesystem only contains the track data for the DLC tracks. Everything else like DLC vehicles, characters, 200cc data and DLC track music is stored as a regular game update for all users.
