= Ribbon texture files =

There are five "ribbon" texture files in the <code>Assets/Texture2D/</code> directory, named <code>ribbon-1.png</code> through <code>ribbon-5.png</code>. Ribbon files are used by the game for the colored ribbon on the corner of a song art when entering a song. <code>ribbon-1.png</code> (blue), <code>ribbon-2.png</code> (yellow) and <code>ribbon-3.png</code> (red) are used for ''Neritic'', ''Photic'' and ''Bathyal'' respectively. It is speculated that ''Abyssal'' and ''Hadal'' charts would've used <code>ribbon-4.png</code> (pink) and <code>ribbon-5.png</code> (purple).

= Unused chart files =

In ''Gadvia'', [[Gadvia:chart file|chart file]]s have filenames ending with <code>D1</code>, <code>D2</code> and <code>D3</code>, for ''Neritic'', ''Photic'' and ''Bathyal'' charts respectively. In the game's files, 60 charts with the suffix <code>D1</code>, 60 charts with the suffix <code>D2</code>, 60 charts with the suffix <code>D3</code>, and 2 charts with the suffix <code>D4</code> have been found. It is speculated that chart files ending with the suffix <code>D4</code> are ''Abyssal'' charts.

The two charts with the suffix <code>D4</code> are:
* <code>UMATrack13_Ch1_D4</code>
** The <code>SongName</code> field is set to <code>"蘭嶼幣"</code> and the <code>Compose</code> field is set to <code>"野東西"</code>, which points to the song [[Gadvia:蘭嶼幣|蘭嶼幣]].
* <code>UMATrack22_Ch1_D4</code>
** The <code>SongName</code> field is set to <code>"rainbow"</code> and the <code>Compose</code> field is set to <code>"ああああ"</code>, which points to the song [[Gadvia:rainbow|rainbow]].
