Cryo dune reverse engineering

Fiddling with Cryo dune (CD Version) for fun:

• Trying to understand how the game works with Spice86 reverse engineering toolkit which allows to run real mode x86 ASM / C# hybrids.
• Rewriting the game in C# bit by bit.

Build & Run

Running it

To run it, ensure that you have DUNE.DAT and DNCDPRG.EXE together in the same folder.

Next, just run the project with dune CD executable as parameter:

git clone https://github.com/OpenRakis/Crygenic
cd Cryogenic/src
dotnet run --Exe C:/path/to/dunecd/DNCDPRG.EXE --UseCodeOverride true

Running it with music and sound effetcs enabled:

Example with Adlib music and PCM voices:

cd Cryogenic/src/Cryogenic
dotnet publish
bin/Release/net8.0/publish/Cryogenic --Exe C:/path/to/dunecd/DNCDPRG.EXE --UseCodeOverride true -a "ADL220 SBP2227"

Building it

• Clone this repo, and build it:

git clone https://github.com/OpenRakis/Crygenic
cd Cryogenic/src
dotnet build
