Pack author's comment
One of the best soundtracks on MSX imho. It was logged wit nezplay so it shows as K051649 and I don’t know how to change it to K052539 (aka SCC-I or SCC+), any help would be appreciated!

SCC+ is indicated by setting bit 31 of the frequency:

Code: Select all

0x9C: K051649/K052539 clock (32 bits)
        Input clock rate in Hz for the K051649 chip. A typical value is
        1789773. It should be 0 if there is no K051649 chip used.
        If bit 31 is set it is a K052539.

Iirc you do that with the following command:

Code: Select all

vgm_ptch -SetHzSCC1 0x80369E99 <file.vgm>

Okay, it took some figuring out and the correct value for these tracks was: -SetHzSCC1:0x801B4F4C
Updated the pack accordingly...

Ah, yes, I forgot the VGM format has a /2 divider on the SCC clock frequency…

Small update...

[sdsnatcher73]

I mistakenly used vgm_facc in my packs (did not RTFM). I've redone them now without using vgm_facc...

I took another look/listen and the loop for track 36 (Goodbye Harry) was sub-optimal. It has been shorted by ~50s now.

Just registered because it sounds like some notes are missing in a few songs. I'm curious if this is just an issue with me or if anyone else can hear this. From what I can tell are affected:

- Twilight of Neo Kobe City is notably missing the high notes in the opening arpeggios, also seems to be reflected in the reverb channels.
- Theme of Snatcher (Part 2) is a similar case.
- Theme of Randam is more subtle, with some of the backing notes missing.

That's just what I can notice. Comparing to the OST recordings or MSX emulation of the songs makes it quite noticeable. I can hear this issue on both foobar2000 2.24.2 (foo_input_vgm 0.30b5) and the site player. Same issue appears across different devices. Unfortunately I can't say if this is an issue with the VGMs themselves, the software playback, or some other issue entirely...
