This isn't a QB topic but I'll try to help anyways. Try searching the QB for the checksum, you may need to switch endianness...you should be able to find it

I sort of hijacked this thread with questions about the QB format a while ago. I figured it was the most relevant thread, but I can open a separate thread if you would prefer. Or a mod could split it into two threads from where I changed the topic back on the first page.
Forging on ahead though, here's what I find when I dissect the PAK file for "Hotel California":
| Code: | I found the section names easily, as they are stored identically as with NOTE format files:
section name = "Chorus 1" checksum = 0x0C658976
section name = "Chorus 2" checksum = 0x2748DAB5
section name = "Intro" checksum = 0x085B59C2
section name = "Intro Solo" checksum = 0x67DBFDEF
section name = "Outro" checksum = 0x249404F8
section name = "Solo A" checksum = 0xD8953790
section name = "Solo B" checksum = 0xF3B86453
section name = "Solo C" checksum = 0xEAA35512
section name = "Solo D" checksum = 0xA5E2C3D5
section name = "Solo E" checksum = 0xBCF9F294
section name = "Verse 1A" checksum = 0x6BAF9FF7
section name = "Verse 1B" checksum = 0x4082CC34
section name = "Verse 2A" checksum = 0x791A3019
section name = "Verse 2B" checksum = 0x523763DA
section name = "Verse 3A" checksum = 0xC1A6577C
section name = "Verse 3B" checksum = 0xEA8B04BF
Elsewhere in the file is where I found references to some of the above checksums. Raw data is as follows:
00 00 00 00 00 00 01 5C (QB file size)
1C 08 02 04 10 04 08 0C 0C 08 02 04 14 02 04 0C 10 10 0C 00 (QB Magic number)
00 20 1C 00 (Start of section?)
9A FF 95 DA (Section name checksum?)
6C 4F 3A FF (File name checksum?)
08 5B 59 C2 (The checksum of the "Intro" section)
00 00 00 00 ???
00 20 1C 00 (Start of section?)
BD 83 17 17 (Section name checksum?)
6C 4F 3A FF (File name checksum?)
67 DB FD EF (The checksum of the "Intro Solo" section)
00 00 00 00 ???
00 20 1C 00 (Start of section?)
34 B1 2A 2F (Section name checksum?)
6C 4F 3A FF (File name checksum?)
6B AF 9F F7 (The checksum of the "Verse 1A" section)
00 00 00 00 ???
00 20 1C 00 (Start of section?)
56 08 AF DE (Section name checksum?)
6C 4F 3A FF (File name checksum?)
40 82 CC 34 (The checksum of the "Verse 1B" section)
00 00 00 00 ???
... |
Most of this seemed to make sense, except I still don't know where the timestamps are being kept. I couldn't find the unknown checksums among the Hotel California guitar marker checksums from the DBG file

0x71EB should be the ms offset of the "Intro Solo" Section...you're missing the part of the file that shows the ms offset for the "Intro" Section...which is 0xC97
I think that is what you should need
Edit: I'll re-post and fill in some of the ???'s (in bold EditEdit: "doesnt work in code sections, the [ b ] 's are there"):
| Code: | [b]00 00 01 00 (Start of first entry)
00 01 54 10
00 01 01 00
90 6B 67 BA
00 00 0C 97 (OFFSET ms of Intro)
00 01 54 20[/b]
00 01 1A 00 (Alternate 2D array section header?)
7D 30 DF 01 ???
9A FF 95 DA (Checksum given above for "Intro" section)
00 00 00 00 ???
00 00 01 00 [b](Start of second record)[/b]
00 01 54 38 ???
00 01 01 00 ???
90 6B 67 BA ???
00 00 71 EB [b](OFFSET ms of Intro Solo)[/b]
00 01 54 48 ???

| Is there a description for these fields written up someplace? I suppose I could make do by finding each section's checksum, rewinding to make sure the 2D array header is there, and then rewinding to grab the timestamp. Thanks again for your help! Hopefully now I can implement this logic and forget this ugly QB format ever existed. |

I don't believe so...I think the hardest thing for you is that you're trying to parse the PAK, not the QB...QB's are heavy with storing offsets to various information, when you use the PAK, you lose the ability to easily find information.

| That's not really a very big limitation, since the PAK file has everything nice and contained. As long as the format is known, I can parse it as formally as necessary to load it all properly. The way I have to parse some things are more hacky than others, but it works. |

I'll be examine a document that describes the GHWT format next. Are there any other GH format variants I need to look into? |
That is odd, if you find any method for the madness in the variation of these files I'll be able to update this tech doc accordingly. |
I just came to find that I was running into this problem because the "vocals" section checksum of 0xE8E6ADCB could appear several times in the NOTE file, but the one with the needed data is the one where the vox note size of 7 is given as the 2nd (or sometimes the 3rd, for some reason) dword after that checksum. I just added a loop to check each instance of the checksum until the expected vox note size was read. It solved the issue I was having. |

|
|
I am working on this .note to .chart converter and I am almost done.
It supports all notes, difficulties, TAPS, SP, Forced notes.
I just need to figure out how to convert ms time to tick time and back.
If anyone knows how this could be achieved, please PM me. :)
Tool download is on my Discord: https://discord.gg/nMBGfgD |

Thank you!
That is very useful :)
]For doing the reverse [.note -> .chart] in other words [ms -> tick], a guy on youtube called Buldy said this:
| Code: |
Tick [the note position in .chart] = (BPM * Resolution * time [in miliseconds]) / 60 000.
Moonscraper (and feedBack) take into account three decimal places of BPM value.
And yes, you need to keep track of what BPM you are currently on. |
And here is a method that seems to work pretty well for me at the moment:
| Code: | Convert current resolution to 192.
divide all the timestamps by (res / 192)
bpm * resolution = bpmres
125,786 * 192 = 24150,912
minute / bpmres = minbpmres
60000 / 24150,912 = X [ 2,484378229691699 ]
( this is for getting ms-time )
ticks * minbpmres = ms
ticks * 2,484378229691699 = 3814 [ms]
( this is for getting tick-time )
ms / minbpmres = tick
3814 / 2,484378229691699 = tick [ 1535,1929728 ]
tick rounded to closest divideable by 192. |
Just posting it here to keep it backed up for people who need to do it in the future on their own projects :)

| After some testing, it seems like the unknown extra byte in the 9 byte variant of note definitions defines ghost status (for drum tracks in Warriors of Rock). |
