Try patching the game for "fast" CPUs. Patch can be found here: http://www.sierrahelp.com/Patches-Updates/Pat … rryUpdates.html

Yes, I found those already, no help. The gosierra script is only one that actually helps, without it sound blaster is not found.

The game is mostly playable, but you'll get occasional crashes. Dog is easiest to reproduce. Changing route in taxi also crashes.

Would it be worth trying a CPU slow down driver?

..and its not completeable. In appx mid game it will freeze.

Just disable the caches. It's safe don't be scared. That should rid you from the need to chase many of those fixes and patches. Use SetMul to disable the caches without needing to fiddle with BIOS settings.

Hi, great idea, but did not help.

I did:
setmul l1d bpd vpd

..and the same result. The dog freezes the game.

Hmmm, what version of Larry 1 have you got? Is this an original disk installation?

Sorry if you already tried, but have you tried the game from a different source online? That happened to me a few times where it was just a faulty corrupted version I was using...

Also, are you launching the game in Win98 or DOS?

Yes, tried many sources. One of my initial ideas was whether its corrupt !

For launching, I used PIF functionality to launch special DOS session from Win98. (I think its not well documented, there are ready made "gaming" PIF:s in C:\Windows). You can define custom config.sys and autoexec.bat in the PIF. It the reboots to those params - seems to work very nicely(??) So when you click the special PIF, it reboots, and goes direct to DOS mode.

Running direct from Win98 it does not work at all.

I haven't tried from say Dos 6.22, for that I need to find a new compactflash card that actually works somewhere.. 😉 It sure is picky.

Nice! I think you already got the best technique to launch a DOS game in Win98...

Have you tried without any sound device configured to see if the game behaves the same?

Oh, what a brilliant question! Without sound, the dog scene went through ok!

I was also wondering, does it want to play a sample, or something like that with the dog?

..So the rationale for the crash could be that even though both OPL and MPU music work, there is issue with samples. I did run DIAGNOSE.EXE, with no issues. But its could be the something deeper.

Quite possible! Maybe with FM sound/music it's not trying to play that sample... Have you tried adlib alone?

OK, tried adlib, and pure mt32. With both the dog pisses as it should. So the sample theory might on to something.

To open it up, can it be related the version of the soundcard? Its a CT2770. I have installed no drivers.

What's the size (in bytes) of your SNDBLAST.DRV?

its 9784. mtblast.drv is 3688.

I have 3670 for MTblast.drv... Give it a try: https://drive.google.com/file/d/1gLLQs84F2sSs … ?usp=drive_link

OK, so yours again say couldn't initialize music hardware

This is probably a little thing. I'm a professional Linux developer myself, no idea on how this DOS/Sierra stuff works.
