I am using DOSBox-X, and the CD version is not installing.
The problem is that I cannot select a drive to install to, and when I press enter to go to select hardware, the drive letter shown is an a with an accent, trying to install anyways fails. What's going on?
I'll try the floppy version in the meantime.
Version 2.0 of the mod is available! https://www.subsim.com/radioroom/showthread.php?t=251370
I'm looking to install it on my DELL HP laptop, windows 10, and it keeps saying it cannot install due to the version, whatever that means, and I'm really wanting to play it, if anybody has suggestions, I'm free and open to them
A large graphic and sound mod is available for Aces of the Deep! You can find all info on the mod and download in this thread at subsim.com:

Which key is it to drop a bomb/torpedo?
Does anyone know which files are needed to play the game in "german" language? I own the original CD of the game. I play with dosbox on Linux.
What remembers ¡¡
i'm nearing 60 back then i was hooked on it. aod command took it to a whole new level (note the nickname.) Thank god Hitler was a fool type XXI was a brain child in 39-40 as hydrogen-peroxide driven boat. I will once again rule the ocean. lol Next louenbrauw on me.
The Silent hunter 3 of its generation. Dynamix produced some quality sims back then from the immensely enjoyable Red Baron to this and more. Nothing was more satisfying than stalking allied convoys, sending merchantmen to the bottom of the ocean then evading the escorts and praying that boom isn't the depth charge that ends your patrol early. Doesn't really stand up to Silent Hunter 3 now, but still a game worth its place on any Submariner fans playlist.
Had this game on floppy back then and loved it the foldout map and everything. started looking for the new release with expansion with supposedly better graphics and more boats. anyways dosbox handles it fine in win 7. would like the later cd version with expansion and all.
For some reason in Linux with DOSBox 0.74, you can not record during navigation at sea. After nearly a year researching I found the solution. We must create the "SAVE" folder inside the folder SIM.
Por alguna razon en Linux con Dosbox 0.74, no se puede grabar durante la navegación en alta mar. Después de casi un año investigando he dado con la solución. Hay que crear la carpeta "SAVE" dentro de la carpeta SIM.
i didn't play this game in its day and now I'm hooked, playing every weekend.
Really good. Somebody should adapt it to Android. In my tablet it will look great!!
I played this for hours! at night ! great game before Silent Hunter I & II came Around !
Happy birthday to me! big 50! over the hill and the brakes are failing! gonna be a rough ride to the bottom of the hill! (hope they put some pillows in the hole because I'm gonna hit hard!)
cccccyyyyyaaaaaa!
Ok! I scanned it all and sent it in! so they should have it all posted soon!, maybe try and get some more screen shots!
can anyone tell me about the expansion disk?
do i need to upload it as well? was this a supplement to the original?
or a complete software package by itself?
Please explain.
I am Jacked! I got it to work! I followed your link and downloaded the defend re loader or whatever, drug the file from my downloads and dropped it in the defend program and whala!
I'm out in the ocean looking for merchant ships!
super cool! thanks guys, I had a floppy with some of my old saved games, anybody know how to upload them?? my email is humpmaster@cableone.net if you have any info for me that would be great and visa versa, I have all the original documentation that came with the game.
Thank you so much for bringing back a quality game that I used to love to play! and now I can enjoy it again! good job!
I just downloaded but it wont install! I have the original on floppy but it is for a 32 bit system, how do I run it on a 64 bit or will it even work?
I want to play this again! it was awesome!
please help!
oh cool
If you have trouble saving the game during patrol (corrupted saves) remember that the game autosaves every 10 minutes in the 20th save slot - just enter load game screen and scroll all the way down ;)
My father gave me this game in 1995; my PC was barely able to run it and often game crashed while attacking enemy convoys.
Realism and longevity were wonderful; graphics not bad (for its time).
Unfortunately I can not save while at sea too. Pleas help!!
the best
DosBox 0.74 + Win7 64 bit - Works Great.
Undoubtedly the best subsim of its time. A challenging game (specially when you try to do a patrol without saving/reloading when you get pounded by the escorts) with lots of replayability to it. Certainly a game that deserved a graphics update without touching the game-play.
I've managed to sunk a 11 000 ton troop transport ship! But damn, I had some hard time getting away from the escorts... This game's awesome!
Works out of the box. Thank you
Man, I must've sunk hundreds of hours into this game when I was a kid. Still the best submarine sim game ever. So excited to play this one again!
GET IT! GET IT NOW! It's really worth it! Quite easy to learn, hard to master, atmospheric, enjoyable, relatively nice graphics for that time, I say GET IT!!!
This is great for fans of the film "Das Boot"
Can't save while at sea. Any ideas on how to fix that?
Otherwise, this is a really enjoyable sim that I'm sad to say I missed the first time around. Glad to have a chance to try it out now!
