This is a WIP project aiming at reversing Cryo's DUNE game.

• bin/floppy : PC DOS floppy version files (LOGO.HNM, BAGDAD.HSQ, DUNE.EXE, LOGO.EXE, ...)
• bin/cd : PC DOS CD version files (DUNE.DAT, DNCDPRG.EXE, DUNE.EXE)
• tools : a set of tools from various sources
• bluegr/scummvm : the resulting ScummVM engine (which is the work of multiple people)
• asm : the original x86 DOS assembly

the bin folder is not part of this repo, as it is copyrighted material.
