DMBuilder 0.90.epsilonDMBuilder will return slowly...
It is now available in a newer version, but still experimental.
The whole code is completely new from the version 0.85 but only offers currently some batch processing. The UI is disabled and will be reactivated later.
Download here this special version of DMBuilder (v0.90.e).
The current version can be used to extract DM2 data from the graphics.dat.
It works best for the PC/MAC version, though there are still errors during the extraction.
It can also generate DM2 graphics.dat files to use as custom graphics/resources for DM2. The generator works through text scripts, so custom generation can be batch processed.
The late DMBuilder version encode faster DM2 images to graphics.dat (though it does not compress them).
