When you look at a video recorded by DOSBox, will you be able to see torn frames when the video is paused? This should tell wether the tearing is inside or outside the emulation.

Hi, thank you for reply

I record this AVI

The problem is there, you can see the tearing

By the way, I have a real 486 machine, and there is not tearing at all. I tested in a Celeron 333mhz PC too, and no tearing neither. Both in real DOS

Thanks

You could try to play with the cycles. Fixed cycles at maybe 20000, and vary to see if it improves.

Hi, thanks

I play with cycles, from 1500 to 30000, in steps of 150

I fixes cycles at 3000, 5000... 20000 and same

Tried too all CPU, etc options (dynamic, full, etc), vga/svideo options, EMS, etc etc

I think I tried all options in dosbox.conf, but tearing remains

In dosbox website, they say it runs "perfect" but maybe is because nobody really tried to do a long play 😊

In ntvdm works great, no tearing, but I really preffer to use DOSBox because i want to just play the game at 1280x960, in ntvdm my screen stretch to native 1280x1024 😀

Is this thread related to last year's thread here: Help - build a Dosbox PC. It was posted that you had video tearing that I could not reproduce. Also, I could not play the above AVI file.

Moreover, mobygames.com does not show that this game was available for DOS. Is this the FM Towns version?

Long story: http://www.softegg.com/products/pm2/index.html
Short story: a leaked beta version floats around. No one has a legitimate copy.

Although the English PM2 is a leaked beta version.
There is a Trad. Chinese version of PM2 for DOS. This game works fine with DOSBox 0.74 official if you boot to real DOS. 😉

I have versions for FM-Towns, PC-98, Mac, Saturn, etc etc of this game, for DOS only the beta if I dont remember bad, Chinese version is for windows

truth5678 , about the old thread, is not the same problem, this old tread was about vsync. And the video, is taken from dosbox windows, in the same folder, is the codec

About vsync, today i test in a custom dosbox, that is fixed in 60hz, perfect vsync (if the game is 70hz, slowdown to 60hz, but vsync is great) and same problem

For now, I dont found any solution

One way to find a solution is to first locate a legitimate copy of the game, so its compatibility would be known. It is not known whether your version is fully compatible with "standard" DOS. For example, if it is a modified FM Towns version, then the video output may be non-standard.

Any version you can find for dos is a legitimate copy, is same beta everywhere, is a official port to DOS

As has been explained, the English DOS version was never formally released, and the leaked beta copy is NOT legitimately obtained software. SoftEgg, the developer, has asked for people to stop pirating the beta.

Back to the question, anyone tried the game?

I tested today in a C2D machine with a dedicated ATI radeon 4550, and same problem. Other games work like a charm, no tearing, no vsync problems

I tested in ntvdm in same machine, and no tearing, just in dosbox

Finally, i tested the game in 8 different computers, 3 desktop and 5 laptops, the destops and two laptops with XP 32, I tested dosbox and ntvdm. 3 laptops with win7 x64 only dosbox. All same tearing in dosbox, and OK in ntvdm

Like i said, in real DOS works perfect too (real 486 and celeron machine)

My saves are personal, but if someone need, i can make a save just to test, I create a princess and play until is possible to do some adventure

For now, all looks like a dosbox problem

The issue isn't dosbox, it's running pirated software. If the software was legitimately obtained, then it would be possible to compare a working copy versus one that does not.

Don't get offended, if you don't like this thread, read another one

My idea with this thread is to find people that can test the game for a possible solution in dosbox, and report the problem, not to talk about the beta

And by the way, the game is in dosbox list

http://www.dosbox.com/comp_list.php?showID=300&letter=P

And yes, the issue probably is in dosbox, or something in the config, because the game works well in real dos. And dosbox is a PC+DOS emulator true?

Expect this thread to get locked soon. pirate ware is a no no here.

Then remove the game from Dosbox support list, because from dosbox website, the forum links goes here

http://www.dosbox.com/comp_list.php?showID=300&letter=P

Yep, locked
