AGFV: 20 years of Star Trek 25th Anniversary

One of the first games I ever played was Star Trek: 25th Anniversary, one of the many gems on the Interplay 10th Anniversary CD that came bundled with my dads Compaq (remember the days when games were bundled?). 25th Anniversary was special in that it combined a “Wing Commander” style combat sim with away missions and mini “episodes” of the original series, kind of like a fourth season. This game and its sequel “Judgment Rites” remain my favorite games of all time and have always found a place on whatever new computer I buy.

Star Trek 25th Disks

Through the magic of Amazon I recently acquired an original floppy copy of the game (8-3.25 inch disks) and in today’s edition of AGFV I’ll show you how to install and run this fine game, even if you’re working with twenty year old floppies like me.

Step One: The first step is easy, but a little tedious. Copy the contents of each floppy disk into a separate folder (Disk 1-8). This process will remind you of the joys of how long it used to take to write files to and from a disk (and these are only about half full!). Unfortunately you need to use separate folders since most of the installation files are a compressed archive that has the same name on each floppy.

Step Two: When you’re done, create a ninth folder called INSTALL and copy the contents of Disk 1 into this folder. Copy all nine disk folders into a folder called “TREK25” and copy this folder to “DBGL\dosroot”.

Step Three: Open up DBGL and click “Add Profile”. The first thing you’ll see is a field for title. You should only need to type “Star Trek 25th” then click the “Consult Moby Games” button. A list of possible matches will appear. Select “Star Trek: 25th Anniversary” and click OK.

First Screen

Step Four: Next Step is configuring the machine specs. Click the “Machine Tab” and look at the cycles field. Usually “Auto” is okay here, but 25th Anniversary can be a little fussy if things run to fast or too slow, so 10000 cycles is best. Everything else can be left at the defaults.

Step Five: Click the “Mounting” tab. This is where we’ll point to our “TREK25” install folder we placed inside the dosroot. All programs by default need at least one drive mounted, the “C:\” drive. Click add. C should be the first drive to come up. In the “as” field, select “dir” and click OK. Click add again and select “A” from the drop down. This will be our simulated floppy drive which we’ll use to install the program. Browse to TREK25\INSTALL and select “floppy” from the “as” field. When you’re finished the mounting portion of your screen will look like this (Click to enlarge):

Second Shot

Step Six: Before clicking OK at the bottom left, Browse to TREK25\INSTALL\INSTALL.EXE for both main and the setup fields. DBGL always requires a program file of some kind to be in the main line before the profile can be created. Click OK to create your profile.

Step Seven: Click Run Setup. This will start the original installation program. By default the program will save to C:\STARTREK, or in reality DOSROOT\STARTREK. Select VGA, Mouse and Keyboard and Soundblaster for the setup questions, then hit enter to begin installation.

Install begins

Step Eight: Installation will run for a minute or two then ask for the next disk. Copy the contents of the corresponding disk into the TREK25\INSTALL folder and press enter to continue. Because we’re mounting this folder as a floppy, changing its contents effectively is like swapping a disk. Typically I just do a CTRL-A to get all the contents of the request disk folder, and then past and overwrite in the INSTALL disk folder. Say yes to an overwrite requests. Repeat for all eight disks (this’ll take 15-20 minutes).

Insert new Floppy

Step Nine: Once installation has completed  DOSBox will close. Click “Edit Profile” and click on the mounting tab. Select the floppy mount statement and click remove. Browse to STARTREK\STARTREK.EXE for the main, and STARTREK\SETUP.EXE for the setup. Your screen should look like this when you’re finished (click to enlarge). Click OK to save changes.

Final Mounting

Step Ten: Click “Run Profile” to start the game (Alt-Enter toggles fullscreen).

  1. Hi Ben — I’m going to be honest, I didn’t read all of this post. I’m just not computer geeky enough to understand most of what you’re talking about (or to want to play a 20 year old game!) But I just had to comment to say that I LOVE the comment: “remember the days when games were bundled.” 🙂

    • Thanks Jo. I know these posts are a little more of a niche interest (hence one of the reasons I reduced the number of them I do, the other being they are a lot of work). Most guides for getting old games to work either don’t go back this far, or assume you’ve pirated it and downloaded it from an abandonware site. I don’t know if I’ve found anyone who’s gone to the trouble of showing how to install a multi-floppy game. For me games are like anything, I always want to have a working copy, I always want to be able to go back and discover what I missed. That’s why I do these from time to time, to share some of the tips I’ve learned. I always appreciate feedback, and maybe for the next one of these I do I’ll cover something a little more recent, maybe only 15 years old 😉

      • I actually think it’s great that you do these posts. I may not do more than skim them, but I know they exist. And I’ve been known to quote your blog to my husband and completely stun him with my niche-geek knowledge. 🙂 Plus, next time he’s complaining that he can’t install some old game that he’s got lying around, I’ll totally come back here and use this guide to do it for him and win huge super-wife points.

    Ben: Followed your instructions carefully for Star Trek 25th using DBGL, but I only have the CD not floppies version. DBGL is fine. This game appears to not run because (per dos window) the game is looking for a CD to be in the CD drive. But need this to run from the hard disk instead because of physical disability makes it hard to always be putting cd’s in and out of the drive bay. Is the CD game version hardcoded to only run from CD bay? Please reply to my email… Thanks for your gaming blog, it’s great, I enjoyed all your gaming entries.

      PS Edit – Got it running fine when I tried using a different dosbox front-end, & also by that point I understood dosbox.conf a bit better. But using this front end I had no issues getting old dos games to run; whereas I had some issues with DBGL. Anyway, I used LaunchBox 3.6 which has vanilla dosbox 0.74. I used a custom dosbox.conf file in each game’s folder. For this game, I tweaked the settings a bit to get it to run nice and sound nice. There are details on dosbox settings for this game posted at vogons.org …
