There was a breakthrough. My brother and I tried and failed to extract the files, so I asked my sister's partner for input. They found the files actually needed to be in a specific folder as follows:
> idx2dec-master > bin > Debug > net5.0
Then they created a script that can decompress the files one after the other (using the forced debug arguments). From the files, I found several different file types (I think this is all of them but I am sleepy and may have missed some):
- F_AGL : .AGL, .GLD
- F_AGLCHR : .AGL, .GLD
- F_BG : .NCGR, .NCLR, .NSCR
- F_BGM : .SSS, .S14
- F_G3D : .NSBMD, .NSBTX, .NSBCA, .NSBTP, .ECA, .GLD, .NSBMA
- F_OBJ : .NANR, .NCER, .NCGR, .NCLR
- F_SCN : .BBQ
- F_TBL : .BBQ, .CHE, .GLD, .MVMP, .NFTR, .AGL
- F_TEX : .GLD
- F_VOICE : .BIN, .IDX
I decided to decompress the files in the F_VOICE category and got a LOT of .bin files. Here's all of the extracted files as well as the extracted voice files in their default formats:
https://mega.nz/file/2ZV2TbTb#KPZCeNO1j_...NH5txcw5T8
I still have a lot to do on this project. I haven't really gotten to test the files myself outside of a few glimpses with some 3D tools. I have a few guesses as to what some of the files are, although I haven't checked them myself yet.
F_AGL has a lot of files with names that make me believe they are the interactable objects or images in the games, like: BANDAI_NAMCO_GAMES, COMMU_BAD, COMMU_GOOD, COMMU_NORMAL, COMMU_PERFECT, D_EDIT_PLAYLISTCURSOR, D_NWF_WIFI_RANKING_TOP, or D_EDIT_PLAYLIST_FRAME.
F_AGLCHR has files for almost every character in the game, so I think these are all likely character portraits. There are also a few extras, likely character effects for Ai, Eri, Ryo, and Ami.
- AIH ... Ai Hidaka
- AMI ... Ami Futami
- AZU ... Azusa Miura
- CHI ... Chihaya Kisaragi
- ERI ... Eri Mizutani
- HAR ... Haruka Amami
- HIB ... Hibiki Ganaha
- IGA ... Yukio Igarashi
- IOR ... Iori Minase
- MAI ... Mai Hidaka
- MAK ... Makoto Kikuchi
- MAM ... Mami Futami
- MAN ... Manami Okamoto
- MIK ... Miki Hoshii
- OZA ... Reiko Ozaki
- RIT ... Ritsuko Akizuki
- RYO ... Ryo Akizuki
- SAI ... Cineria
- TAK ... Takane Shijou
- TKD ... Soichi Takeda
- YAY ... Yayoi Takatsuki
- YUK ... Yukiho Hagiwara
- YUM ... Yumeko Sakurai
- EFF_AMI
- EFF_RYO
- FX_AIH
- FX_ERI
- FX_RYO
F_BG has a lot of assorted files that I'm curious as to what they are for. A lot of them seem to be related to events or menus, like AUDITION_DAN, D_COSTUME_BG, D_ACCESSORY_BG, D_NWL_UNITLIVE_BG01, LESSON_RANK, QR_SQUARE, U_STAGE_DANCE_LESSON_ROOM_FRONT. All of the stages are listed here with proper names in the files:
- U_STAGE_AUDITION_STAGE
- U_STAGE_DANCE_LESSON_ROOM_FRONT
- U_STAGE_ISLANDSEA
- U_STAGE_LIVEHOUSE
- U_STAGE_NODATA
- U_STAGE_NWLLIVESTAGE
- U_STAGE_PUBLICHALL
- U_STAGE_TOKYODOME
F_BGM has what I'm assuming are all of the music related files, not just BGM. The majority of these file names match the songs of 'THE IDOLM@STER BEST OF 765+876=!! BGM COLLECTION' or the playable songs in Dearly Stars (Agent Yoru o Yuku, ALIVE, Kiramekirari, etc.). There are some differences though, with 5 tracks not being listed on the BGM collection or in game songs (that I know of).
- HELLO_GAME
- HELLO_LESSON
- MELO_GMW
- MELO_MAT
- MELO_PRE
F_G3D is all of the 3D related items, as far as I can tell. I want to work on this one the most, but there's a lot to it, so I'm just going to say there's a lot going on in there. Some of them seem to have exported oddly, but I'm not entirely sure why.
F_OBJ is other interactible objects. I see ACCESSORY_OBJ, COSTUME_OBJ, D_DANCE_DETAIL_OBJ, D_NWL_TOUCH_OBJ, D_SCROLL_BAR_OBJ, all of the dance panels listed, MEMORIES_NUMBER, MENU_ITEM, and several more objects.
F_SCN is full of BBQ files. They all have a bunch of assorted names like AIH_A01_AUD01, ERI_B02_SUB01_MES, RYO_LES_RESULT_RIT_MES, RYO_SUN_TALK, TOUCH_AIH_GOP, MAKERLOGO, etc. I am not sure what these are to be honest. Possibly text and routes in the game?
F_TBL I think must have something to do with sequences. AGE_CAMERA I would imagine would refer to Agent Yoru o Yuku's default camera, AGE_FACE I would imagine would refer to facial expresions, AGE_LIP would be mouth sync, AGE_HANDS would be hand movements, etc. I see files like ML_ERI_C02_MAIL, AUD_REEL_TABLE, IDOLIMAGELEVELTABLE, QRCODEPRESENTKEYTABLE, and a lot of others in there as well though, so there's got to be more here.
F_TEX has a lot of file names that sound like background images. B2D_876PRO_MEETING, B2D_876PRO_FLOOR_DAYTIME, B2D_876PRO_FLOOR_NIGHTTIME, B2D_ROOM_ERI, B2D_THEMEPARK, B2D_KITCHEN_HIDAKA all sound like locations. There are also files with HIT_BG_00, HIT_BG_01, HIT_CHR_00, HIT_CHR_01 file names that I have no idea what they refer to.
F_VOICE is what I can only assume is the vocal lines within the game. The files are separated by AI, ERI, RYO and COMXX. I'd imagine that COMXX would be the rest of the vocal cast (765PRO) as only Ai, Eri, and Ryo are voiced out of the characters beyond the 765 idols.
All in all, a lot to explore. I have next to no experience when it comes to ripping files or extracting them, but I feel like I've already accomplished a lot here. I want to keep looking into these files and see more and more! There's a lot of intricacies here and I'd like to keep exploring them. I also am curious as to what is going on with the 3D files. I have definitely opened them and had them open normally but later opened them and the vertices are all over the place. I will be looking more into them soon.
