in Sound/BgmInfoData


relate to the bahps, trying to find out what the fuck they're about


seem to be divided in 4 parts: header, block 0, block 1, block 2 (whatever they're about)

the file is always 0x244 bytes long (parts are respectively 0x4, 0x100, 0x40, 0x100 bytes long)


header (4 bytes)
00: ???
01: ?? always zero
02: number of entries in blocks 0 and 1
03: ?? always 4


block 0:
4 bytes per entry
bahp positions in samples

block 1:
one byte per entry
bahp type(??), values: 01, 02, 03, 04

block 2:
oddball shit, all the files have it filled with the same pattern repeating, 40 44 48 4C

well yeah, block 0 is the positions of the events, I tried laying them on a graph and it pretty much fits


block 1 must be dance type or something -- observed values are: 01, 02, 03, 04

in the Sabaku file, consecutive bahps use values 01 then 03, lone bahps use 02 and 04 (except the bahp in the beginning which uses 03)


also, the block0 positions are in samples (sample rate is typically 32000Hz)

maybe the first byte in the file is the song ID or something


so far:
ATHLETIC: 71
ATHLETIC_FAST: 88
CHIJOU: 64
CHIJOU_FAST: 78
CHIKA: 61
CHIKA_FAST: 74
KAZAN: 78
KAZAN_FAST: 90

.. nope, there are dupes, derpo

here's a null BBID file: https://kuribo64.net/get.php?id=yJD1ylYgzhiNHyyq

try replacing a song with a custom one, and replacing the associated BBID with this one

(might need fixing the first byte in the file, but dunno)

We need to investigate BigRedSound.bcsar. It has strings that refer to the BGM songs. Pretty sure there's more to it.
