LSL6 Gravis Ultrasound Audio
« on: February 06, 2025, 11:56:20 PM »
After getting Gravis Ultrasound emulation working in DOSBox for a non-sierra project, I read LSL6 was one of the few games compatible with the card.

I downloaded the sierra GUS drivers from Sierrahelp, but couldn't seem to get it working.

Searching this site didn't turn up much and I couldn't find any youtube videos showing off lsl6 GUS audio. Anyone already do the leg work on this?

I'm curious if it sounds better or worse than the SB audio. GUS seems to be a crapshoot.

I have a couple of Sierra GUS drivers on the site. I would imagine that you are using the GUS32 driver for LSL6. I have not messed with the GUS drivers/emulation much, but it does have a TSR program that has to be run befor the game. Did you use a batch file to launch it and then the game?

I was trying the GMGUS drivers, but after your comment I downloaded the GUS32 driver from this page. I ran 'loadpats -ill6.ini', but when I start the game I get:

Error 53: Can't find sound driver 'C:\SIERRA\GKCD\GUSMIDI.DRV'.

Putting the drivers in that folder does work. but I'm not sure it was worth the hassle.

That folder would indicate the path inside of DOSBox, not your computer, of course. Is the parent folder of the 'SIERRA' folder mounted as C:? i.e., if the actual folder is C:\Oldgames\SIERRA\GKCD\ then the command in the [autoexec] section of your dosbox.conf should be

mount c C:\Oldgames

then DOSBox will see the game installed in 'C:\SIERRA\GKCD' and the GUSMIDI.DRV should be in the GKCD directory.

It works fine. I just thought it was odd that it requires the drivers to be in a GK folder. Other non-sierra games find the GUS midi patch folder as defined in the dosbox config - normally C:\ULTRASND

Well, that driver was provided by Sierra.
