  • VMD's can be injected by copying an VMD to the root directory of the Game, and rename it from what you wanna replace it with.


  • DEV6 uses LET files as Fonts.
  • DEV6 is backwards compatible with older LET files as like from Gobliins 2.
  • You can replace an font if you found out which Font is been used by the Game, and then extract it from an other game like Gobliins 2, then rename the Name of the font to that was the original of DEV6's and copy it into the root directory of the Game.
