Pokémon Brilliant Diamond can be officially purchased and downloaded through the following methods:

: Approximately 4.3 GB (the unpatched base game).

: The v0 version lacks several major features that were added via a day-one patch (v1.1.0), such as the game's opening and ending movies, local/online communication features (Union Room), and access to the Battle Zone.

: This base version is famous among speedrunners and collectors because it contains numerous original glitches, such as "Menu Overlap" and "cloning exploits," most of which were patched in later versions like v1.1.2 or v1.1.3.
