Karja's Battle Dress is a DLC outfit unavailable in all NISA-published versions of Ys X, though it was available for the CLE version on Steam. Since the costume already exists in the game's files regardless of DLC (complete with translation), it can easily be restored in the NISA PC port with a simple mod.
Active Voice portraits of Adol and Karja drawn in a different art style, and in 128x128 instead of 256x256. These can be seen in the test map, test_debug. The portraits and full images ended up on some merch on Falcom's official shop.
A rough map of the Obelia Gulf with some layout differences; notably an isolated circular area in the southeast part of the map, the Flumen Strait. (Note: The raw image of the final map does not include islands or landmarks on its own.)
A similar image can be found in the game's artbook, but edited to resemble the final map.
Miscellaneous placeholders for common images throughout the game.
