I have a bunch of old Blood maps on disc but have no clue how to get them to work. I have Gog's version of Blood as well as DosBox. I'm running Windows 7. I'd also like to play some of the new maps people have made.

Help?

You need to edit your dosboxBlood.conf file. Near the bottom of the text you will see a few lines that read

mount c: "."
c:
blood.exe
exit

You will want to edit the Blood.exe line.

For whole episodes, you should have an ini file that will reference the maps that make up the episode.

Be sure the ini file and the episode maps are in the same directory as Blood.exe and modify your dosboxBlood.conf file so the Blood.exe line reads

Blood.exe -ini episodeName.ini

For single maps you, again, be sure the map is in the same directory as your Blood.exe
and edit your dosboxBlood.conf file as such:

Blood.exe -map mapName.map

That worked! Thanks!!
