Currently in developpement : RTSB (Return To Strike Back - dev. name

It's a tool to port RTC dungeon text file to a dsb module dungeon.lua
Beware, it will still require some work from the dungeon designer to make a working DSB dungeon, especially if there's a lot of custom stuff !!
Release of Original DM postponed until the tool is done ( but then you'll see immediatly CSB too...

EDIT :
The tool is mostly ready expect a release in less than a week !
EDIT :
If you have a custom dungeon, to implement your new items, enter the list as follow at the beginning of obj_list.txt :
RTC_ITEM_NAME CORRESPONDING_DSB_ITEM_NAME
RTC_ITEM_NAME CORRESPONDING_DSB_ITEM_NAME
...
where the blank is of any type. only the parity and order counts : never put something else than a
rtc <space or tab or new line> dsb
pair, new line are ignored, so you can space out the file.
But of course DSB won't guess what the new item is alone, so you have to add it in the objects.lua of your dungeon folder.
