The NRS drivers seem to work well enough on SQ3, but have glitches on KQ1 SCI, such as the first time you open the door of the witch's house there is a couple of seconds of ear-grinding noise at the end of the sample, but every time after the first seems fine.
Doesn't happen here. Then again I don't keep track of older, possibly error-prone, versions of my stuff being distributed.

What are "low-res replacements", and what exactly are you all trying to do? If the goal is to get both MT-32 music and Sound Blaster PCM, but the latter only for those sound effects that are not just recorded from the MT-32, then modifying PCM-waveform-bearing sound resources to indicate whether it's an MT-32-recorded waveform or not, and having a custom MTBLAST.DRV look for that flag, is unavoidable. I've done this before.

Do you have newer, possibly less error-prone, versions of the drivers available? 😀

The first MTBLAST driver for QFG2 uses separate SOUND.XXX files, so it can already do that: either the separate file is there or not.

Actually, it may be avoidable. The approach being used by the second driver is for it to hack the interpreter to play digital sounds despite the MT-32 device ID, so you don't need modified or separate sound resources, but at the moment it lacks selectivity. It may be possible to refine the second approach to only play specific digital sounds by number, perhaps going by a table within the driver. A table would be specific to QFG2, but the interpreter hacking tends to make it specific anyway.
With the first or second approach, still need someone to go through the digital sounds and identify which are just sampled MT-32 sounds so they can be excluded. The SCI tool linked by collector seems to work well enough for the job.
Attached find patch for Quest for Glory II. Because only two PCM sound effects are not recorded from the MT-32 (and yes, I went through all of them), just providing those two modified sound resources as separate files is the simplest option, certainly simpler than modifying the interpreter executable.
Also find MTBLAST.DRV for King's Quest I. Since in this game all PCM sound effects sound different from their respective MIDI data, no selectivity is needed. I got no static when knocking on the witch house door; if you still do, report.

Play the MIDI data on your MT-32, then play the PCM sound data. If they sound the same, minus the lower sampling rate in the PCM sound data, you know that it's been sampled from the MT-32.
Does your MTBLAST for QFG2 do something more than the others in this thread? Seems to be more-or-less the same thing with SOUND.XXX files. Granted that the separate SOUND.XXX is easier, but collector seemed to like more the idea of no extra resource files.
For my own ears, I prefer some of the other digital sounds over the MT-32 sounds, if for nothing else than the seeming lack of reverb. But it is, of course, subjective.
I tried the KQ1 MTBLAST.DRV and don't get the noise when opening the witch house door for the first time, so that's an improvement. I also tried it with SQ3 and it seems to work fine there as well. Thanks for the updated version of the driver. Do you also have a newer SNDBLAST.DRV with stereo FM for SCI0?

This could also be that sometimes with MT-32 SFX, the reverb for the current song will intervene or conflict with the reverb (or lack thereof) for the SFX.
For me, the advantage is hearing them in stereo (think SQ4, the "LiftOff" sound where the starship pans in both channels) versus (relatively) low quality PCM in mono.

NRS, great to see you! Glad to see you're still around.
Excellent idea! makes a ton more sense than manually flagging each resource. I didn't think there were many other than the genie laugh, since that's all people mention.. if I may ask, what in blazes is the second one? Ad Avis screaming at the end?

Very interesting as well! I had no idea all SFX were PCM. And also, genius, makes a lot more sense to just allow all SFX to be played PCM and music on the MT-32.
Great post, great thread. Thanks to Tikalat for his investigatory work also 😀

The evil starts when you find out that each soundtrack piece is compressed per device. No lumping together like the SCI files.
So only the SB will have the digital PCM effects embedded in the track (Adlib / SB). Using anything else will not make them visible.
Plus the 2nd intro lightning bolt (play track #4) - doesn't even exist for non-SB. Never called or used.
Means you have use normal Adlib ($00) ID to give you the PCM. Then trick the game to use other ID ($07/ 0C) to get your normal MIDI. Game does keep music + SE in 2 separate memory segments (useful to know in figuring this out).
Some basic stuff attached - just fixes the SB init problem with fast CPUs. Has some decompressed MIDI binary blobs for others to look over. SX.OVL merger code.
Had a cheap idea for SQ3 + QFG2 driver-only versions: (inside the driver) check MIDI data and look for 3 pairs of magic bytes. Turn on/off digital as needed for matching pairs.
Bloatware. Non-award winning stuff. Only works with _original_ game. Classic amateurish. Yeah. Tikalat-style. 😉
If collector doesn't need any more specialized driver-only game hacks though, I'll call it quits for now. Do some private hobbyist stuff for awhile.
(like hack-merging a few more Sierra drivers/interpreters for my own fun or failing to do same for MI1-2)
Let the smart people take care of things. Why create more problems for myself? :p
On Krondor, the game's music is designed to be heard on a SC-55, I don't think the MT-32 support is anything special, in fact, I think the MT-32 just plays the GM files with a GM SysEx bank, ala SQ5.
I think the MIDI SFX sound fine on a SC-55, but that's just me 😉
Hey, so, PCM sound effects won't play in Krondor CD version if you have GM selected? Is that right?
I guess you're right about Krondor. I think I lost sight of which MIDI synth was the one to use in my rage about not being able to hear the digital sounds along with it 😀

Right you are. Same with Krondor floppy (unpatched or patched).

There's quite enough PCM-exclusive ones too. Even for cutscenes. Plus ~15-25 short speech clips.
The end of ch8 sounded so~ wrong to me - maybe it's my expectations though. Same with ch6 start (or was it 7?). Should listen to the SB track to see if it's just me.
Gunshot is used enough for SE - spells, lightning. Other areas. I want better (if PCM is better).

That doesn't seem to be the case. Unless I am completely mistaken, all sound and music is in an archive with the extension .SX, with each tune compressed with the LZHUF compression algorithm. The decompression code is just written to skip unwanted bytes instead of adding them to the decompressed data buffer.
The cleanest way is still to just add the reference to the PCM track to the track lists of devices [h] and (07 and 0C). Then the .SX archive needs to be rebuilt and put into the game directory to be used as a replacement of the original file encapsulated in KRONDOR.001.

Looking over the list at the end of FRP.SX, that looks like all the names. Working backwards from the driver, I wouldn't have ever noticed that - they seemed to keep massaging the data over and over. Never got a complete soundtrack of all devices per tune - just separately. Chased those bytes around and never figured out where they were coming from.

I can wait many more years to pick this up again. My interest in DOS-related hacking just got completely drained.
Thanks for looking into this though. I'm sure others will become motivated to finish this.
All right, dearly beloved. I don't know this game at all, so this may be completely wrong after the title sequence, but I can now get General MIDI sound with PCM samples.
KRONDOR.EXE must be modified so that it even bothers to call up AUDBLAST.DRV with any RESOURCE.CFG entry other than SNDBLAST.DRV. The modification could be done more elegantly; right now it is forced to always load AUDBLAST.DRV, no matter the setting.
SX.OVL includes an AUDBLAST.DRV that doesn't fail to initialize on faster machines. Inappropriate trivia: the IRQ check routine that always fails wasn't done by Sierra but just copied from Creative Labs' very first Sound Blaster SDK.
FRP.SX has the sound resources modified so that PCM tracks are included in the [h] and track lists as well.
I have only tried it with some "free download on Sierra's website to promote the game Betrayal in Antara" that's dated 1997 (readme file says "Betrayal at Krondor FREE RELEASE, Version 1.02"), so beware.
edit:
Thank you so very much!!!! Act1 = "Hold there!" (thought it was "Hello there!" - bad memory)
Going to make a speech list because of this. 😀
edit2:
Okay did some more testing comparisons. Gen Midi music is correct - choirs, percussion, themes. Special digital SE are right - definitely better than some of the synth ones.
Battles - Alistair is right. I remember digital but listening much closer, I can sort out the Adlib synth. So SC-55 synth it is! (already correct).
Now if Alistair could give NewRisingSun the sound files with the corrected SQ5 drum program #s, he'd have performed 3 miracles in a mere week with that release.
edit3:
Should also mention that my 1.02 CD saves do load with NewRisingSun's EXE. Be warned though!
From EXE strings:
- CD = Version 1.02 CD
- Floppy 1.0 -> 1.2 patch = Version 1.2
- Antara = Version 1.00 (....? that's weird)
Yeah, the CS in "CS_HARP" stands for Chris Stevens, who made a MT-32 patch bank to emulate the GM sounds. It's pretty horrible though (listen to Krondor or SQ5 on a MT-32 and you'll see why!), I don't know why they didn't just use the Sierra one.. Although it's far from perfect too.
Right you are. Same with Krondor floppy (unpatched or patched).
OK, neat. Well, now NRS has fixed it, anyway 😉

Sure. Krondor is a game where the SFX would be preferable in PCM because it's not a MT-32 game natively. I wonder if any other GM games fall into this category..That have the problem that is.

I'm pretty sure NRS already knows which are which, i think he told me originally 😉 But I'm happy to supply him with the track names if he has time and needs the info.
My main NRS project I want completed someday is Willy Beamish with CD version and MT-32 support, but we'll see. 😀 He's done so much for me I should dedicate my website in his honour- hey, maybe I'm onto something.. 😉 We'll see, 10th anniversary coming up.
The MTBLAST patch for Willy CD was never finished because Cloudschatze mentioned that although most things work, some sound effects were missing. I can't find anything wrong from listening to the introduction, so here goes. Report if you find something missing.
EDIT: Uploaded new version.

Only did Beamish once on Sega CD. Not familiar at all memory-wise.
I think he's worthy of a tribute - basically done more than most of us could combined. :approval:
Now I get this itch to do some Scumm game that I've heard about a unused feature but never had the skill to bother. With all that open-source work, should be easier. 😀

I've only sent this out via private message so far. This patch for SQ5 allows for using all sixteen MIDI channels on General MIDI, so that the Glockenspiel and the Reverse Cymbal no longer get cut off by the Alert sound during the flight simulator sequence in the introduction. And drum map changes are now sent to the output device. New compared to the version I sent out privately is automatic remapping of illegal drum map numbers to the ones recognized by GS level 1, which is required to get them to sound right on later Sound Canvases. 4.PAT adds a voice reserve sysex to better make use of the sixteen MIDI channels, and ADL.DRV is the stereo FM driver.

Could someone please provide an overview of all the versions and patches to this silly game? The websites on this game are confusing as hell, why with the "free" version not really being free and supposedly bugged, and some patch originally being an update to a floppy version but also fixing bugs in the free version, and similar incomprehensible gibberish.
