The board has been cleaned up to the degree that it merits a news announcement. The following changes have been made:

• Duplicate runs (exact same submissions being in both the glitchless category and the any% category) have been removed (formally rejected/reverted). The rule set for the any% category allows runs of any kind, but there have been glitchless submissions placed in both categories and it was a mistake for me to allow there to be duplicates in the first place. Duplicates only amount to clutter and confusion, so if you intend to only run glitchless, please only submit your run to the glitchless category. It would probably be a better idea to change the any% category into "glitched" specifically to avoid this issue so that change may happen in the future.
• Game Boy Color as a platform for the game has been removed from this board. No runs had been submitted for this version so this has no effect on this board. The Game Boy Color version is a port that is fairly different except for story. For anyone interested in the GBC version of the game, the board is called Déjà Vu I & II: The Casebooks of Ace Harding.
• In addition, 8-bit Anthology runs can be found at 8-bit Adventure Anthology: Volume I. No runs have been submitted for this version although a forum post was made asking about it. The Anthology version uses a mouse hack of the game which makes navigation significantly faster than the original release. Instead of just banning these runs, it made more sense to move these into an entirely different board, although the actual content of the game should be just the same (the capsule warp works on that version). The new board is named after the actual published title of the collection, which is not just formally correct but also causes less confusion while searching for Deja Vu here at speedrun.com

With regards to duplicate runs, I would like to add that only identical runs at the time of writing have been reverted. This means that the run that was reverted to could also be a former duplicate, but without any way of confirming that, they will be left as they are at this moment. Earlier I mentioned the possibility of clearing things up by changing any% into glitched, but I will make an announcement when (or even if) that decision is made.

Hopefully these changes have resulted in an even clearer and concise board.
