So, finally I got through and made also a save. The time I got through the DoxBox was so stable that I could reload and retry so much I wanted without the occurrence of the freeze. Very confusing.

I have been having this problem as well and was able to fix it on my machine. The trait which seems to cause it is the rendering method. I had been getting the crash when using ddraw, but with surface, it goes away. Just for edification, I did not notice the problem on the Garidian ship in the beginning, but any warbird or what-have-you. I tested it by deliberately setting a course to Romulan space.

I had the same problem as a final unity, where I got to that one mission with the outpost you got to attack that solo warbird and it hung up when I destroyed it. and after I shut down dosbox and restarted the program it let me get past it. Any info as to why that happens would be helpful. I have had a strange crash just now that has me concerned. I made it to allonor (or how ever you spell that) the chodak capital planet and I beam down and picard says something then it throws me back into dos box.

It should probably be known that I'm running the game with all the contents of the game in a folder called \DOS\CD, and the game installed at \DOS\STTNG and "Mount d C:\DOS\CD" and "Mount c C:\DOS" and the game runs fine after I changed the path in the game. The game is a bit choppy pops in the sound almost clock work every min but Ive grown use to it be nice to get rid of it though. Other then that I haven't had a problem.

I'm assuming that the numbers such as the sound volume are in Hex format? I read somewhere that the irq should be set at 7? there any truth to this?

I'm also running a modified version of the STTNG.OVL file remade using DOS32a

In the STRING file I'm not sure what the DPixel=OFF, and the UniVESA=OFF are, but everything related to the sound was off before and I changed them to on.

(Non related praise mostly directed at the developers of the program)
I must say that other then crusader No regret, I haven't ever had any problems running my old classic games that I have enjoyed through out the history of computers. (oh and a few probs with WC/privateer but thats prob fixed now) Just the fact that I can get this far in this game again after having the cd so long and not being able to do anything with it is a joy. To play these games mainly privateer, I have even purchased older computers in hopes of getting them to run again. Needless to say this is a much better way to solve our weird gaming needs. The fact that this is the first time I have ever felt the need to post is probably a good thing, but the thanks is long over due, but well deserved.

Unless you changed settings in dosbox.conf, IRQ should be 7 and not 5

I realise this is a very long time after the incident, but thought it was worth posting in case anyone is still having an issue with it in emulator or web page game form now.

If you are haivng your game crashing out at the point a ship explodes - you need to go back to the set up prompt and change the video resolution down to the lowest.

Depending on what you are playing it on, you need to exit to DOS (using the datapad menu in the game and selecting QUIT. Then at the dos prompt run SETUP.exe to enter the game set up and go to the video options and select the lowest res and colour option (just above autodetect). Then save and exit out and reload the game (STTNG.exe from the DOS prompt). Then when you get to that same point/battle/ship explosion, it should happen without an issue.

Just remember to save your game as regularly as you can, if you want to shift the resolution back up for the rest of the game, as you may have to go back and do it again if you find it occurs in other battles.

Hopefully this might help the odd causal player in the future.

(I have been playing it via . and I was frustrated when it happened, then it suddenly came back to me that this happened when I had the game back in the 90's too and the solution just jumped into my head!)

Hallo!

I'm running Star Trek: The Next Generation: A Final Unity with the newest DosBox 0.70. Everything works, thanks to the developers, really fine. 😁 But the trouble is that the game freezes when the enemy ship explodes. 😢 Sometimes it also freezes earlier. Besides, tactical works fine, too. However, the critical point is the explosion.
How do I get beyond that point?
