Proper filename (IMO):
World Soccer Winning Eleven 6 + World Soccer Winning Eleven 2002 (Japan) (Promotion DVD)or alternatively (but as argued before, I think it's better to put it in Disc Title and leave only game titles in Title field):
World Soccer Winning Eleven 6 + World Soccer Winning Eleven 2002 - Promotion DVD (Japan)
Neither: the "Promotion DVD" is an edition variant of "Demo".
The information about what it came bundled with should go in comments or edition field instead of the filename.
Why do you remove that information from the Edition field, if so?
It is not convenient. I don't see this name in this cd scan
What exactly don't you see on the CD scan? The only doubtful parts there are "World" (since it's the USA release, according to the barcode) and "Disc 4" (since there's no number on it, so it should be "Baldur's Gate - The Original Saga (World) (Soundtrack - Music by Michael Hoenig)"). Regarding the next tag, this was already discussed years ago, the CDDA, VCD and DVDV/BDV dumps should be somehow tagged to indicate the system they represent. Since Dremora didn't like the idea to add the bonus discs into the same dats with their 'parent' games, we need to tag them properly, so, people, who only interested in PSX-related audio discs (for example) could easily sort out the needed files and ignore the rest.
Ideally, it should contain the game title, but at the very least, it should contain the system name or acronym and something to understand the reason of its inclusion into the dat. Something like "Bundled with PSX Game", "Bundled with Magazine", "Promo for PSX game", "Related to PSX game" (also, do these variants need the articles? since the "PSX game" technically means many copies) or something similar. Another possible variant is to put some tag before the title, something like "[PC] Baldur's Gate - The Original Saga (World) (Soundtrack - Music by Michael Hoenig)". I'm all ears to your ideas.
