The .img file is a disk image (likely a floppy disk, but could be a HDD).

Okay thats a bit helpful with understanding what I have, DosBox Game Launcher has an option to mount something as either .hdi (for harddrives), .ima (for foppy) and .iso for cd-roms.

As I mentioned on my post... I only have a .img file (with a .sub and .ccd) ... not any of the ones mentioned in the guide you provided, and also I am hoping to be able to figure out how to do it using DosBox Game Launcher not DosBox standalone.

I can mount the .img myself and be able to explore the files inside it, and I see an install.exe inside it amongst other files. Am supposed to copy the files inside it somewhere and get Dosbox Launcher to install it?

Finally got it to run by doing the following:
Extract all the stuff from the .img and put it in a folder, used the DosBox Game Launcher Game Wizard and told it where the install.exe in that new folder was...it proceeded to install. After that I went to edit the game profile and chose play.bat as the main exe (just as the Dos installer had told me to do) otherwise it would just crash when ran.

So finally got it to run...

Now the problem is that:
1)Cutscenes run too fast while gameplay runs at normal speed (so changing cycles constantly would not work for actually playing the game, its a ligthgun game btw)

2)There is no sound at all... tried adding a command to also mount the original .img but still nothing (again I forced it to mount, Dosbox Game Launcher only accepts .cue/iso/hdi/ima as valid)
I also tried running the setup.bat but that just gives me empty blue screen the moment I choose sound settings on Dos.

As the .img comes with a .sub and a .ccd, then it is probably a ClonceCD image file, as in https://en.wikipedia.org/wiki/CloneCD_Control_File .

There might be other ways, but the most straightforward way to convert it to a bin/cue would be to mount it with Virtual CloneDrive in Windows, and then image the mounted disc with imgburn.

It is quite likely you will need to have the CD image mounted in DOSBox while playing the game in order for it to work properly.

In my experience, DOSBox imgmount works with img/cue just fine.

The point is, this isn't img/cue; this is a .img with a .ccd and .sub.

Is "img/cue" something you even see regularly? I've only ever seen .cue files with .bin files.

Thanks for now mentioning that you have a corresponding CloneCD .ccd file with the image.

You'll need to convert the .ccd to a .cue either by re-converting the entire image to BIN/CUE format (as Jorpho's suggested), or leave the IMG as-is and simply convert the CCD file using of these ccd2cue utilities:

- https://www.gnu.org/software/ccd2cue/

Sorry, maybe I wasn't clear enough.

CloneCD img/ccd/sub + cue => works with imgmount.
Cue-file can be created for any CloneCD image and used with only the img-file just like bin/cue. At least I've never had any problems doing this.
