Add 'BGM Currently Playing' feature

[drojf]

Sometimes we get asked what a certain BGM is in the Discord.

We could implement a feature similar to what the original game has, which displays the name of the BGM being played. Currently, the game/mod has no mapping of filename -> actual song name, so we'd need to add that in somehow (probably a .json file inside each BGM folder). There's also the complication of there being multiple BGM folders (such as the OGBGM folder)

I think the original game has an (option?) which shows the name of the currently playing BGM for a few seconds when it starts playing.

@andOlga suggested we instead display it on the pause menu (right click menu). I think this is easier to implement, and also allows you to check what BGM is playing at any time without adding additional shortcuts or buttons. I could pretty easily add a button which shows the file on disk too.

It's probably a good idea to display both the filename and the song name, since you may want to just find which file it is on disk (and also for our mod's debugging purposes, to check the correct BGM is playing at any given time)

TODO:

• Improve appearance
• fill out bgm databse (for both question and answer, if the same database can't be used for both)
• add an indicator of where the BGM file comes from (default BGM, GIN's BGM, or any other bgm source)

I've basically got this working. The main things to do are:

• improve appearance (optional)
• create filename -> BGM name database for the BGM and OGBGM folders
  • This is confusing to do due to the april update changes. However it looks like there is a good list on the Higurashi wiki of the BGM, which is probably the best place to start

Relevant to the OGBGM Folder:

• Check this wiki page https://07th-expansion.fandom.com/wiki/Higurashi_no_Naku_Koro_ni_Kai/Music
• Check this comment by me: Feature: enable the 2020 demo BGM? onikakushi#203 (comment)

Relevant to the BGM folder:

• Check this wiki page for a mapping of old BGM to new BGM: https://07th-expansion.fandom.com/wiki/Higurashi_Music_Replacements

Relevant to both:

• Check file metadata file hints at BGM name
• Higurashi music change list (may be out of date): https://docs.google.com/spreadsheets/d/1c4Ou9ssNuTAsxJozD0nnc-fzfaIwAdk30F2JhhQGmw4/edit#gid=844796254
• Using some music ID'ing software to compare to an existing list of music files with the proper names (like a Higurashi music collection)

So far I have the following for the Answer arcs. Probably easier to make a shared google sheets, fill it in there, then generate the JSON File from it.

    "bgmList":
    {
        "4" : {
            "name": "Digital Network",
            "nameJP": "Digital Network"
        },
        "mion" : {
            "name": "Spring Step (Mion)",
            "nameJP": "Spring Step (Mion)"
        }
    }
}

Starting putting together all the information I can find into this document: https://docs.google.com/spreadsheets/d/1CzZ6IBOPmDozdatWM2rol1DR2xjIaySSKY5XQV4yhdI/edit#gid=1854485371

This "Mario3573" has uploaded every BGM that appears in Higurashi in chronological order, with the BGM name (not filename): https://www.youtube.com/playlist?list=PL0YDec1hvdtU_2JXMxO-sByllanTyTrfb

Ordered by appearance in the VN, includes both the original versions and the Radiata Alice versions from the 07th-Mod Patch.

Also doesn't have those annoying anime screenshot thumbnail spoilers.

Rei added, all its new BGM comes from Daybreak. See you in 2024 for Hou.

For now, I'll automatically match our mod's BGM against this playlist (using audio similarity matching) to get all the BGM names (without manually checking any of them), as this seems like a good reference. This is a lot easier than what I was trying to do earlier. If there are any missing, those can be fixed manually.

I think it should be good enough that if there are any errors, we can correct them later.

Another source for song names from the (console game?): https://gall.dcinside.com/mgallery/board/view/?id=higurashi&no=58473 - from the screenshot, they extracted the bgm names from the game files

Besides the textual list, there is a download of every bgm, which has been renamed as hmXX_XX - so I can add it to my BGM matching script easily.

This feature has been added to all chapters (except console which hasn't had its DLL updated yet), see:
