Yep. Everything, YM2203 and YM2608, is doing this to me and I'm guessing it's something on my end...

Can you give me M files you are trying to convert? Checked ones from hoot and there's no runtime 100 error in S98 rendering or S98->VGM conversion.

Sure: http://www.sendspace.com/file/ce0vsc
These are the two tracks I have been primarily working with.

Right, totally forgot that in_vgm does that. Thank you.

Here you go: http://tails.bloodheaven.net/VGMPP/_etc ... _wrk/tm03/
I had no errors with conversion.

CMD log:
pmd2s98 01MM.M
pmd2s98 05MM.M
s982 01MM.s98 -noadpcm -v 40
s982 05MM.s98 -noadpcm -v 40

A little off-topic here, but since you all seem to have issues with in_vgm's cache, I'll add an option to disable the cache (or maybe make it more intelligent).

Ah, I figured out what I was doing wrong! I wasn't letting pmd2s98 finish converting... Well, everything's working now. Thanks for your guys' help with this. :D

Even though this was mentioned via IRC, I'll post it here anyway.
---ADPCM detection seems to (not) work under specific circumstances in which it can not be clearly determined.
---PMD2S98 s98's generally do not convert well with s982vgm. (eg: missing multi-freq mode, dropped notes etc.) Hoot s98's work fine.

Probably should note -v ## SSG offset requirements are also very different with pmd2s98 s98's vs hoot s98's. (Currently doing comparisons with music from same games between players, possibly suggesting either have their own SSG volume adjustments on s98 creation)

OK, we discussed that in IRC. Conclusions:

1. Auto ADCM detection will be changed to -adpcm switch, it sucked anyway.
2. It appears to be PMD problem, it can fallback to FM3ex mode to play 4 FM sounds and use 4 separate channels. MaliceX used -opn option to get YM2203 tracks but 4th channel was leaved out since YM2203 has only 3 FM tracks.

Updated ADPCM converter. Link in first post. And Happy New Year, let's hope that forum will keep storing awesome stuff and became more stable (Hi Oerg).

Apologies for the bump, but I've noticed quite a number of PC-98 sets being submitted, so I would like to clarify.

Did we ever manage to find the correct values for SSG volume? Are the sets currently on site using this value, or will they have faulty FM/PSG volume ratio?

So far I used values found "by ear", this needs some investiogation for sure but i don't know where to start. Preharps you happen to know how hoot stores these?

<option name="fm_mix" value="0"/>
<option name="ssg_mix" value="-13"/>

Those are default values for PC98 with either PC-9801-26K or Speak Board

<option name="fm_mix" value="0"/>
<option name="ssg_mix" value="-18"/>

Default values for PC98 with PC-9801-86

<option name="fm_mix" value="0"/>
<option name="ssg_mix" value="-2"/>

Default values for PC88

Many drivers override these with custom values.

Do these numbers represent decibels?

I don't think so, just general balance I think - you should ask Hoot devs to clarify though.

I'm not sure if you couldn't change the balance with a BIOS/motherboard switch on a real PC-98, which could amount to the different values used by different games.
