slowing down dosemu?

slowing down dosemu?

Cheers all,

I recently tried Syndicate Wars, which I still own, in dosemu. I was  
pleasantly surprised that dosemu ran it quickly. (dosbox is too slow  
for this game). In fact, the game speed is too fast to be playable, and  
I'm wondering whether there is anything I can do to slow things down.

I've tried tweaking the cpuspeed configuration option, as well as  
turning on the cycle counter, but things are still going too fast.  
Maybe the game isn't using the rtc properly to time the game?

any ideas greatly appreciated

Cheers,
Kacper

What dosemu version is that?
1.2.2 have a serious bug which makes
some games to run incredibly fast.
If this is the case, try 1.3.1.
Also note that you have to use dos32a
to run Syndicate reliably. With dos4gw
it may crash.

Didn't have troubles with crashing, but never heard of dos32a before,  
thanks! However, Syndicate Wars is still running too fast, even with  
dosemu 1.3.1. What other things can I do?

By the way, the debian dosemu packages seem to have been orphaned at  
version 1.2.1. I took the changes made by the old maintainers and  
merged them into 1.3.1, thereby making a a 1.3.1 debian package. The  
dosemu-freedos package also needs to be updated so that it doesn't use  
comcom.com anymore, but I wasn't up to the task, so I just dropped a  
new command.com in the appropriate place.

The crash usually happens if you
press the key in the game intro
to skip it. If you use mouse to
skip it, then no crash. Does it
work the same way for you? That
assumes you are using dos4gw 1.8,
which is what my Syndicate Wars
have. With dos4gw 1.97 it works
better (the real problem is not
in dosemu and not even in dos4gw
actually).

> thanks! However, Syndicate Wars is still running too fast
Sorry, the bug appeared to have
been fixed 3 days after 1.3.1 was
released :( For some very strange
reasons I thought the fix is in
1.3.1, but it appears not.
Can you please try the CVS code?
It is a bit unstable at a moment,
but should work OK for Syndicate.
Otherwise you can try 1.2.1.
Not that I can reproduce your speed
problem under 1.2.2, but trying the
fixed version still worthy before
anything else.
What CPU do you have?

My Syndicate Wars came with dos4gw 1.97, and pressing a key in the  
intro doesn't crash anything. dos32a works nicely too.

Syndicate Wars under the latest CVS version is still too fast to be  
playable - no change from 1.2.1 nor 1.3.1

I'm running a dual athlon mp 2400+

Cheers,

Is this possible to get that Syndicate
somewhere?

OK, then you can try the slowdown
patches from here:
http://sourceforge.net/tracker/index.php?func=detail&aid=716137&group_id=49784&atid=457450

> I'm running a dual athlon mp 2400+
Wow, are you sure it works properly
(not too fast) under the pure DOS
without dosemu?

I got my copy off my swars cdrom. I can put a tarball up for grabs, but  
the thing is 100mb, bzipped. I could rip out the movies, but it's  
really the maps that are taking up the space. On that same note, is it  
possible to get your version of swars somewhere?

Thanks, will do, though these patches are from newyear's of 2004- will  
they apply? I guess I'll find out.

Don't know. Well, I'd try if I had a dos floppy. I guess you're right,  
I should make myself a bootable freedos floppy and try this out, to be  
sure it's not a game bug. I'll try this and get back to you.

Cheers,
Kacper
