OpenLara for 3DS - DOSBox trouble

Maximumbeans · Aug 7, 2022

I'm trying to get OpenLara set up and I'm running into trouble with the given instructions. I'm told to run:

mount C .
imgmount d ".\game.dat" -t iso -fs iso
xcopy D:\DATA\ C:\DATA\
xcopy D:\FMV\ C:\FMV\

in DOSBox, but it tells me "The image must be on a host or local drive". My laptop has an SSD C: drive and an HDD on the D: drive, I don't know if that throws up any issues because I have no idea what I'm doing, I'm just trying to follow the given instructions.

I'm using the GOG version for the assets if that helps. If anybody can shed some light on this I'd be greatly in your debt.

I don't know either. Why are you using DOSBox on your laptop to set up a 3DS application?

Maybe you can start with a link to whatever instructions you're trying to follow?

To take a wild guess, you probably need to run "C:" after "mount C ." to switch to the mounted drive.

I'm under the impression that's what I need to do to get the level files, maybe I'm being dense. This page and others makes it seem like I have to do this in order to get the necessary files for it to work.

Okay, did you follow the instructions? Did "go to ..\Steam\steamapps\common\Tomb Raider (I)\ and run dosbox.exe" ? Because if you just randomly ran DOSBox from some other directory, that would probably cause a problem.

As far as I remember the instructions are from retroarch (you can just search libretro-openlara). They have a video setup guide on youtube, the title is RetroArch - How to Setup: OpenLara (the tutorial for getting data files from the Steam version starts at about 1:35, I added the link in the page).

I can't, the files aren't there as it's the GOG version. I've been following them in the equivalent folders but dosbox really seems to have an issue with paths and I'm not sure why.

Thank you for this! The video unfortunately doesn't solve my issue but a comment there has put me roughly in the right direction.

Maybe you could say what you did differently for the benefit of future readers?

My next suggestion was going to be to skip DOSBox entirely and just open game.dat with 7-zip instead.

Not sure I love the slightly patronising tone but yeah good idea.

Following a comment on YouTube, apparently you need to have the game.gog (for the GOG version) file in the same folder as DOSBox. I also used this version of the autoexec which worked for me:

mount C .
imgmount d ".\game.gog" -t iso -fs
xcopy D:\DATA\ C:\DATA\
xcopy D:\FMV\ C:\FMV\

Using a combo of information from here and here I've got it working.
