# OpenRakis
This is a WIP project aiming at reversing Cryo's DUNE game.
## Project structure
* *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](https://github.com/bluegr/scummvm/tree/dune/engines/dune) : 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.

# Existing efforts
### Engines
[madmoose/dune](https://github.com/madmoose/dune) (Uses SCUMMVM, and can decode videos)
[madmoose/dune-disassembly](https://github.com/madmoose/dune-disassembly): Disassembly work on the PC CD DOS version.
[scummvm/cryo](https://github.com/scummvm/scummvm/tree/master/engines/cryo) (for Lost Eden, a very similar game from Cryo)
[scummvm-cryo](https://github.com/elyosh/scummvm-cryo) ([Scummvm Wiki page](https://wiki.scummvm.org/index.php?title=Dune))
[DUNE revival project](https://sourceforge.net/p/dunerevival/code/HEAD/tree/) ([GitHub copy](https://github.com/sonicpp/dunerevival-code)) (uses [SCUMMVM](https://www.scummvm.org/) too)
