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:
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:
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…

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.
