Hello,
I'm using a Mac. Seems this game is supposed to work. However, when I click 'PLAY', it dims, then goes light again and nothing happens. I've removed the re-installed the game several times but nothing changes.

Judgment Rights works perfectly, just not this one.

Any ideas?

Thanks

Gary

I'm having the same issue on MacOS 10.15.1. Just downloaded both games and only Judgement Rights works.

I wrote a support ticket and it turns out the game is runs on a 32bit architecture and my mac is 64bit. You may be having the same issue. Support says there's a port in progress, but no timeline for when it'll ship.

I'm having the same problem on the WIndows version. I'm running WIndows 10.

I too am having this problem on windows 10

Same issue here, Mac Catalina. JR runs, but 25th doesn't. The reason...

1. JR runs on Dosbox which DOES work on Catalina now.
2. 25th runs on BOXER (a wrapper for Dosbox), which DOES NOT currently work on Catalina.

Technically, we should be able to grab the game disk from 25th mac app; digging around in the app's contents I see the "Star Trek 25th.boxer" which contains folder "TREKCD" that has all the original DOS game files.

It would be great if someone at GOG would update 25th to use Dosbox instead of BOXER, so that we can install and manage the game through GOG GALAXY. But for the time being, we should be able to grab the game disk and run it through DOSBOX manually.

I was just looking at this trying to figure out why MacOS wasn't listed as a supported OS. It's unfortunate that Boxer doesn't appear to have been maintained at all in the last 5 years. It's unclear to me at a glance if the DOSBox project addressed the core issue preventing Boxer from compiling full 64-bit, but still, Boxer appears to have been abandoned by its maintainer. (It's also unclear to me why DOSBox is still hosted in an SVN repository on Sourceforge, but I digress)

[EDIT: It looks like MaddTheSane forked the repo and is busy at work on it. He's hasn't put out any downloadable releases that I can see though so one would be stuck with building the app themselves.]

I'm still not sure why GOG hasn't already replaced the original Boxer based release with one simply running on DOSBox. At most I think it should only take someone an hour or two. I suppose they could be waiting on ScummVM. Looking at they're commit history, work on their STARTREK engine has been fairly active recently but it doesn't appear that it will be ready very soon.

[EDIT 2: MaddTheSane has posted a release of his work on Boxer starting with version 2.0.0. This build of Boxer is 64-bit and works with Catalina and Big Sur. It can be found here.]

[EDIT 3: Additionally, as of 9/21/2021, I just downloaded the manual installer to try and review how one might get the old Boxer install working with the new Boxer release, it appears that the GOG team has removed Boxer and gone back to a straight DOSBox install. I noted however that it is still not showing up as a MacOS compatible game in GOG Galaxy]

It's 64 bit now and runs like a DOS game.
