Re: Sierra/Dynamix sound driver hacking

Posted on 2017-05-27, 19:56

in DOS
Actually, it should be considered an error in my driver that it ignores the loop field, even if I may subjectively like it that way. Attached find an updated version of driver for KQ1 that corrects this. It also corrects an error in the sample rate calculation for pre-SB16 cards when the sampling …

though it seems to cut the door opening sound effect off prematurely as seen in the video I posted. The interpreter calls the sound driver's D_STOPSND function when the "inside of the house" room is being loaded. The SierraHelp driver (which may well be an older version of my driver) ignores that …

The issue is caused by calling the setboard() function without the "| mod_screen" part But how could that part have disappeared when recompiling the game? I think I have fixed the lava animation and switch-flipping screen update issue in all three executables at the locations that K1n9_Duk3 …

Thank-you. That should help a lot. and the compiler decided it was a good idea to read the value from bd[x][y] before calling msg_block() As I understand the C standard , the order of evaluation in this case is undefined, so the programmer was wrong to assume a particular order. and the debugging …

I never noticed that the lava was supposed to be animated, having used v1.2d as a reference before. It's definitely something in the original v1.2d executables. I have a distribution that has both v1.2b (as JJFILE1.EXE) and v1.2d (as JJFILE01.EXE) in the same directory. JJFILE1 (v1.2b) has animated …

ther than the stereo effect, is that really what Froelich would have heard? If so, then by all means add it. I only noticed now that Dan Froelich has put up a recording of FUNKY.ROL . While it has some additional reverb applied to it, you can hear that it sounds quite different from SBFMDRV's …

Updated and reuploaded JILLUPD and JILLFM yet again. JJFILE1-3.EXE as well as the supplied SBFMDRV.COM now take their settings from the BLASTER= environment variable. I had to add 328 additional bytes to each of the three main executable files for this. Testing the various settings exposed another …

Copying over the files from the OLD subdirectory reverses JILLUPD. And JILLA.BAT avoids JILLFM, as you already know. Querying the BLASTER environment variable is of course possible, but is not something that can be done in a few bytes. And Worx seems to be hard-wired to DMA 1, I think. Changing this …

Having debugged Jill's sample caching code, it's becoming plain to me what the problem is: The game caches four samples at a time. If all four slots are used up and a sample is requested that is not in the cache, the sample that has been used the least so far gets replaced by reading directly from …

In addition to the mixer issue, there are two remaining problems: Worx toolkit's method of IRQ detection fails under Windows 98. Basically, the routine starts a short DMA transfer and checks whether the interrupt service routine has been invoked. Such a method is not uncommon, but other sound …

Ah. Is that utility on the Creative SBPro driver disks? Then I can take a look and at least make EPICFM exit gracefully. Speaking of mixer, I noticed that Jill annoyingly writes its own mixer settings without asking the user. Maybe I'll patch that out as well, because I almost fell out of my chair …

Well, then I have absolutely no idea. You can PM me with a zip of your Jill directory as it is, so I can see whether the patch applied correctly or not, but other than that, I'm stumped.

Unfortunately, I was unable to reproduce any freezing, both using DOSBox as well as actual hardware running pure DOS. I have however changed the code a little to prevent what I could imagine might theoretically cause problems in certain scenarios. Try the attached EPICFM and tell me if it fixes …

The first archive demonstrates games that are sometimes mentioned as sounding different between MT and CM, but which MUNT (as far as I can hear) emulates correctly when using v1.07 ROMs. The second archive demonstrates games that MUNT does not seem to emulate correctly even with v1.07 ROMs. They …

Yeah, yeah. Run PATCH.BAT to make changes to the Sound Blaster code that should prevent dropouts on the Sound Blaster 16, similar to what I have done with "Jill of the Jungle". There only seems to be one version of Xargon, so no need for an update patch here. (Unless there are also four different …
