What determines whether events will stop the music currently playing? (PM3, eventBGM.dat, etc) | Persona Modding | Page 1

dusky forum Oct 11, 2023, 3:33 PM

#

Some events in P4G, when called, will not stop music that is playing in the background until their next BGM call (E105_001, E295_001, etc). This allows you to have music from the prior events continuing to play during those events.

However, some other events do stop music, so you can't continue music from previous events. One of those events is E455_502.

I'm trying to find out what exactly determines that because I want to have music from E455_501 continuing to play into E455_502. Nothing in their PM2/3s stands out though, and eventBGM.dat doesn't even seem to have a lot of the events in the first place.

#

Have you tried the 50/50 strat

#

Deleting 50% of stuff (most likely Unit entries) and seeing if the music stops

#

If it does, try the other 50. Then keeping cutting in half until you find the entry responsible.

dusky forum Oct 11, 2023, 4:24 PM

#

I haven't. Honestly I was avoiding doing that bc I didn't know if I would break things or not lol

#

bc I was sort of under the impression that the unit entries controlled like, model movement and such in the event. I can try that though and see if that gets me anywhere 🤔

spiral quartz Oct 11, 2023, 4:41 PM

#

It does but you're looking for music not those

dusky forum Oct 11, 2023, 4:46 PM

#

that's usually stored in the PM3, yeah? the problem I'm running into is that there isn't anything relevant there that stands out from any of the other event files

#

I also tried deleting around half of the unit entries, then the other half, and it doesn't seem like that did anything. did the same thing with ambience just to make sure. testing a few more things to make sure though

#

🤔 I don't know if it's actually anything to do with the PM1/2/3 files at all. I swapped in the respective files from E295_001, and aside from the voice lines being wrong (didn't switch the awb at all), it played exactly as intended - except it still cut off the music

spiral quartz Oct 11, 2023, 4:56 PM

#

Sounds like it's not in those then

#

Have you checked for a bf

dusky forum Oct 11, 2023, 4:58 PM

#

i've been looking around, so far the only thing I found was in event_data/script/E455_502.bf.... which only decompiles into this and some message files that don't seem relevant

#

this doesn't look relevant either but I am not familiar with flowscript haha

#

I'm just wondering if there's something else comparable to cmmeventbgm.dat, with the other events in it. that file seems to only have social link events in it, but as I found out months ago, there are story events with nothing called in the PM3, that just work regardless 🤔

spiral quartz Oct 11, 2023, 5:05 PM

#

Could be

#

Or the low chance of exe fuckery

dusky forum Oct 11, 2023, 5:06 PM

#

oh god

#

yeah if it's exe stuff, I have... no idea what I'm doing there 😭

#

I'd have to like, decompile the exe in that case right?

forest gulch Oct 11, 2023, 9:47 PM

#

Is this happening when calling the event from the mod menu? If not it could be stopped before the call to the event in whatever bf is doing that

forest gulch Oct 11, 2023, 10:05 PM

#

nvm, I just tested myself and I see it just always happens...

#

Well I'd try replacing the pm3 with one from an event where this doesn't happen then if that changes nothing do the pm2

dusky forum Oct 11, 2023, 10:23 PM

#

I already did unfortunately </3

forest gulch Oct 11, 2023, 10:24 PM

#

rip

#

What if you replace the pm1 as well? Just replace the entire event...

dusky forum Oct 11, 2023, 10:24 PM

#

it seems like it's not related to the PM_ files because even when I switched in the files for E295_001, it cut the music that was playing at the time

forest gulch Oct 11, 2023, 10:24 PM

#

Oh, ok

dusky forum Oct 11, 2023, 10:24 PM

#

the only thing is that the audio was wrong bc I never changed it but I'm not sure if the sound banks would really control that logic anyways

forest gulch Oct 11, 2023, 10:26 PM

#

Well, I guess whatever's doing it must be in another file naotothink

dusky forum Oct 11, 2023, 10:26 PM

#

yeah, I looked a bit more earlier before deciding to just take a break, but the only other file I could think of was cmmEventBGM.dat, which unfortunately doesn't have it

#

mudkip had brought up the possibility of it being handled in the exe. does that sound likely at all to you? 🤔

seems like an odd thing to keep in the exe though...

forest gulch Oct 11, 2023, 10:37 PM

#

That seems pretty unlikely, I'd expect it's in some file somewhere. I wouldn't say it's completely impossible though

dusky forum Oct 11, 2023, 10:42 PM

#

I sure hope not lol

#

I'll keep looking in a little bit, if you think you have any ideas where this file could be though, let me know

spiral quartz Oct 11, 2023, 10:48 PM

#

dusky forum mudkip had brought up the possibility of it being handled in the exe. does that ...

pensbe

#

I said low chance specifically so you wouldn't go digging around in exe until you had lost all hope

forest gulch Oct 11, 2023, 10:49 PM

#

I'd prefer looking in the exe than randomly looking through files lol

#

I'll see if I can find anything as well

#

I do still doubt it's actually hardcoded, but in theory I should be able to find where it's coming from if it isn't

#

Where is the eventBGM.dat you've talked about btw? Ik you said you couldn't see it in there but I'd like to see what it is for myself

dusky forum Oct 11, 2023, 11:06 PM

#

it's either init.bin or init_free.bin

#

inside there it's in like event/cmm

forest gulch Oct 11, 2023, 11:07 PM

#

Oh yeah, I see

#

Ty

dusky forum Oct 11, 2023, 11:07 PM

#

np

#

there's a 010 template I used to look through that file, so I guess if that template is inaccurate it could be in there

#

although I doubt it

forest gulch Oct 11, 2023, 11:08 PM

#

Could you send that template

dusky forum Oct 11, 2023, 11:08 PM

#

forest gulch I'd prefer looking in the exe than randomly looking through files lol

searching through files kills my motivation so quickly LMAO. thank you for the help

#

yeah can you give me a few minutes? I'm eating dinner right now haha

#

Sure, no rush

here ya go

forest gulch Oct 11, 2023, 11:19 PM

#

Ah, I see why you say it isn't there.

dusky forum Oct 11, 2023, 11:21 PM

#

yeah, it seems it only covers BGM for SL events and such

forest gulch Oct 11, 2023, 11:21 PM

#

So do non social link events just always have it in the pm2 or pm3?

dusky forum Oct 11, 2023, 11:22 PM

#

99% of the time it seems to be in the PM3 (or PM2 for songs treated as ambience)

#

I believe there might be a couple where the songs are called elsewhere but I don't remember if it was an SL event or not

forest gulch Oct 11, 2023, 11:24 PM

#

Do you know where that elsewhere is or is it some unknown?

dusky forum Oct 11, 2023, 11:25 PM

#

if it was a SL event I'm remembering, cmmEventBGM. if not, unknown

dusky forum Oct 11, 2023, 11:26 PM

#

forest gulch So do non social link events just always have it in the pm2 or pm3?

I made a help thread a while ago that might have info related to this, let me get back to you

#

maybe it was a social link event that didnt have the BGM call in the PM3. as far as I can tell at least from looking at that old thread lol

forest gulch Oct 11, 2023, 11:44 PM

#

I'll have a proper look into this later today, for now I should stop

dusky forum Oct 12, 2023, 12:33 AM

#

alright. thanks, appreciate it

modest valley Oct 12, 2023, 12:49 PM

#

bit of a long shot but could the id be what determines if bgm persists, like if an event id is < 500. events seem to do that for voice lines, only loading an audio file for ids < 600 or something

dusky forum Oct 12, 2023, 3:44 PM

#

I hope not haha. that's a possibility though, it's not like I've tested to see if that is or isn't the case.

most of the story events have BGM in their PM3, most of the social link events are in the BGM dat. but these Golden events are just there in between lol

dusky forum Oct 13, 2023, 3:59 PM

#

forest gulch I'll have a proper look into this later today, for now I should stop

did you have any luck looking into it, if you have?

dusky forum Oct 13, 2023, 6:54 PM

#

i dug through all the files again and nothing stood out to me, I'm just so confused about what exactly is causing this 😭

forest gulch Oct 13, 2023, 11:28 PM

#

I didn't end up looking into it more. I kinda ended up getting side tracked looking into event editor stuff (didn't really find anything useful, just strings...)
Anyway, I'll try and actually look into it today maybe

#

Did you try the event id theory?

spiral quartz Oct 13, 2023, 11:44 PM

#

That one neko person got the event editor working in p4g32 iirc

forest gulch Oct 13, 2023, 11:44 PM

#

I don't think they got it working but yeah, they definitely got further than I have

dusky forum Oct 13, 2023, 11:44 PM

#

no worries, and I have not tried that theory yet. I wonder if that's really the case though bc P4G does have those voiced events for SLs every so often

forest gulch Oct 13, 2023, 11:45 PM

#

I'm pretty sure it's just the max rank events that are voiced for s.links

dusky forum Oct 13, 2023, 11:46 PM

#

there's some random non rank 10 links that are voiced

#

I'm not sure if there's a specific pattern to it but I know like Rise's rank 8 is fully voiced

forest gulch Oct 13, 2023, 11:47 PM

#

Oh, I didn't realise. That's weird

dusky forum Oct 13, 2023, 11:48 PM

#

I thought maybe they had all confessions voiced but that's not the case lmao so maybe there is no pattern for that

#

in any case I can look further into it but I kinda doubt there is a pattern to that....

spiral quartz Oct 13, 2023, 11:48 PM

#

Naotos confession is fully voiced too

#

Idk about chie or yukiko

dusky forum Oct 13, 2023, 11:49 PM

#

Yukiko's isn't

#

I lied I looked at the wrong rank, it is

#

chie's is too so I guess confessions are also voiced

dusky forum Oct 14, 2023, 2:43 AM

#

every E44_ event with no explicit BGM call at the start of the event seem to have the same thing happen (the music cuts out)... so maybe it is to do with the IDs of the event?

#

not just the new Golden events either

spiral quartz Oct 14, 2023, 3:05 AM

#

Doesn't sound out of the ordinary

#

EXE has a check for ids having voice awbs but loads them based on id anyway abhorant

dusky forum Oct 14, 2023, 7:13 AM

#

I hate persona modding sometimes

#

😭

#

I never actually replaced any of the events so I can't totally confirm but everything I did test had the music consistently cut off 😔 so I just wonder if it really is down to it being in a specific ID range. just bugs me because it's inconsistent with the other events as far as I can tell

modest valley Oct 14, 2023, 11:13 AM

#

any patterns you noticed?

dusky forum Oct 14, 2023, 3:35 PM

#

my current running theory is that you might have been right 😭

#

I haven't been able to find any other files controlling whether BGM stops or not in my game dumps

#

I wonder if it's controlled in the exe or if it's just hard coded somehow. but I don't know how to like... look inside the exe or do exe patches

spiral quartz Oct 14, 2023, 3:38 PM

#

I found the voice stuff by just popping exe in hex editor

#

Could just look up files or ids

dusky forum Oct 14, 2023, 3:42 PM

#

~~huh, you can do that?~~

spiral quartz Oct 14, 2023, 3:43 PM

#

open an exe in a hex editor? yeah

dusky forum Oct 14, 2023, 3:43 PM

#

how did you end up finding it anyways? if you're opening it in a hex editor it's just going to be various bytes right

spiral quartz Oct 14, 2023, 3:43 PM

#

wont be anywhere near as detailed as ghidra but it has strings you can check

spiral quartz Oct 14, 2023, 3:44 PM

#

spiral quartz I found the voice stuff by just popping exe in hex editor

~~it ended up not being how it worked but I did find it~~

#

might at least point you in some direction

modest valley Oct 14, 2023, 3:44 PM

#

the voice thing you're talking about was a string though, easier to spot than assembly instructions (assuming it is id related)

spiral quartz Oct 14, 2023, 3:45 PM

#

ye

#

#

(then they have hardcoded id shit anyway abhorant )

dusky forum Oct 14, 2023, 3:46 PM

oh huh, that's cool

I have never ever done anything with exe stuff before so this is all foreign to me tbh lol

do you have a save file for testing e455_501/502 or are using mod menu?

I tried both

#

#

this may be my inexperience with looking inside exes lol, but i have no idea what i'm looking for lol
although this looks like something!!! not sure what to do with it though lol

#

there's also a reference to a few specific events but it's just to load textures, nothing to do with BGM or whatever

forest gulch Oct 14, 2023, 10:10 PM

#

I'm pretty sure that's stuff from some kind of event editor or debug menu. I don't think it's that helpful for this (for the last three days Ghidra's been aggressively analysing instructions in the hopes that I can find a reference to functions that use those, I'm not very hopeful at this point though, it kinda looks like the actual functions were removed and only some string formatting was left...)

#

I'll see if I can just copy the project so I can actually use Ghidra (while it's analysing it's basically unusable)

dusky forum Oct 14, 2023, 10:44 PM

#

imagine if we had access to an event editor in P4G like the one in P3F... that'd be really nice

#

hopefully you do manage to find something in ghidra though :') honestly I didn't expect a question this simple to get this crazy lol but here we are

modest valley Oct 15, 2023, 1:29 PM

#

naodead well i cant figure it out, doesn't seem to be around the code for queuing(?) up event bgm or actually playing it. hopefully someone who can actually re has better luck 😔

dusky forum Oct 16, 2023, 4:04 AM

#

dang 😔

#

here's what I have found out though: mudkip suggested i try loading a new event with a different ID. I copied over E265_001, an event I know doesn't cut music, and called it E265_002. Apparently, the music cuts out for this one though

#

that would suggest to me that music might be allowed to continue playing for certain event IDs but not for others

#

perhaps if I replace E265_001 or something with my desired event, and then edit the scheduler so that the proper events are called, it could work. bit of a jank solution though, if it even works

dusky forum Oct 16, 2023, 5:51 AM

#

this is half working so far. if I can figure out how to call different events for Marie's dungeon, I think this should work. (I'm having trouble with the flowscript stuff but I thought it'd be better in a new help thread)

edit: this may not work after all 😭
