When I click on the OK button in the new game screen, it just comes back to the title screen. :/

How do you start the game?
With the shortcut provided with the GOG-installer?

I'm having the same problem. For me it doesn't always happen. It feels or seems to me that dosbox doesn't sync with MOO all the time or something. It's quite annoying though.

I installed this years ago, so I'm before the GOG desktop installer thingy.

I actually have both MOO and MOO2 on floppies, bought originally in the 1990's, but I lack the required drive to play anymore.

I keep getting the installed failed message, with the disc not accessable. any help on this?

Do you people use the latest Master of Orion installer (GOG-18)?

Did anyone ever solve this? To be fair, I last played this on WinME, which still had a limited DOS layer and DOSBox wasn't required, but the install through Galaxy leaves a lot to be desired.

Like DigDug and Squid, selecting a saved game sends me back to the main menu, but I don't even get to click the OK button, just trying to select a game sends me back. Using "Continue Game" from the main menu more often than not gets me black screen for several minutes (record: 17 minutes before I killed DOSBox from the task manager and rebooted) if the UI loads at all.

On top of that, in the rare instance I actually get the game running, it is sooooo slooooow. Five to 7 seconds from a button click to the game responding to the click; waiting for the next turn while the slow-as-molasses map shows ship movements can take 7 minutes or more.

The entire install folder for MOO and for the DOSBox subfolder are excluded from AV activity. Firewall settings shouldn't affect b/c there is no online play.

It didn't run this slowly on a 386 running DOS 6.22. Why is it this slow on a Pentium i5 quad with 16 Mb RAM and a high end graphics card? And the failure to launch issue is really unacceptable, considering this was a game that didn't need tweaking to run well in actual DOS.

How can I determine if the latest installer was used? Is it already installed if Galaxy is up-to-date?

[EDIT] I found another thread in which someone gave instructions for editing the DOSBox config, and that improved the speed immensely. But there is still the problem that I only get the game to launch from the main menu once out of every 7-8 tries. I have noticed that if the main menu screen flickers at the moment I click, the game will never launch (or at least I'm staring at black screen for many minutes until I kill it and reboot). If it doesn't flicker, the UI launches within 5 seconds. Is this a Win10 issue, is there another DOSBox config setting responsible, does anyone have a workaround?

The version 0.74 of DOSBox used with the game is ancient and works badly with Windows 10. Solution: Download and manually install a development version and transfer game to that. Better solution: Get the developers to put out an official new version whereafter GOG will for sure move to that.

Changing to windowed mode, and back again if you prefer that and right clicking on the game screen can help, occasionally.

Game is slow, you say? GOG used the DOSBox's default speed for the game, which is awfully slow. Increase cycles to above 4000 (if your computer can manage that but it should if from the last 15 years). I use 5000 or 6000 and change the DOSBox settings to remember that.

I had the same problem until I changed the video settings in the DOSBox Config. I changed it to:

Graphic mode: OpenGL
Select "Keep Aspect Ratio"
Scaling Engine: Normal3X

MOO1 doesn't like some of DOSBox's graphic modes for some reason.

Hopefully this helps.

Thanks for both responses (sorry for the delayed reply, I used to get a purple dot next to the Community menu in Galaxy when there was a response, but I guess that's not working anymore?).

The other thread I mentioned in my edit suggested ddraw as the graphic mode value, and 9000 cycles. ThemKen had replied in that thread that 5000 was sufficient. 9000 worked for me, but may be excessive. I'll try the lower value too.

I'll try to install a newer DosBox, but it's been years since I had to deal with setting that up (main reason I moved to GOG was so I wouldn't have to mess with it anymore, HA). Maybe I'll try switching to windowed first.

Now if only there were a way to fix the blatant AI cheating in Final War (spontaneous generation of 50 pop colonies, spontaneous REgeneration of colonies as soon as I've destroyed them, existence of 0 pop colonies, and the usual nonsense), we'd have a perfect game.

As I said, it would be much better if there would be a newer version of DOSBox released.

Cycles: If you open a program to monitor your processor usage and keep an eye on that while raising the cycles, you can take care not to stress that one core too far (not much over 90%) while increasing but you will not see much benefit beyond 5000ish. Those specific problems not encountered by me with or without the fan patch but then I just about never play on the highest difficulty. What they do is share all technology and enter into an alliance with all of them.
