castelobranco: If you want to use OpenLara instead of the packed in DosBox, you will need to extract the files. The instructions that the OpenLara developers give to explain this is terrible. Here is what I did to get it to work:

You will need to open "dosboxTR_single.conf" using Notepad or something like it.

You should see about seven lines of code underneath a heading called [autoexec] that starts with "mount C ".."" and ends with "exit" You will need to put a "#" before each line. This will prevent that code from running.

After that, you will need to enter:

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

Save it and then run the game. You should see the DosBox terminal fill the screen and start giving a list of files that it has copied. If so, then you are successful. After DosBox gets done, then simply go back and undo what you did to the config file before.

For reference, I have so far done this with the first Tomb Raider and not with any of the sequels.
