You can run Doom inside (DOS) Doom, for real #Doom #Modding @Gaming @_kgsws_
Youtube user kgsws has modified the classic game Doom to be able to run Doom inside Doom itself.
I have found a code execution exploit in the original DOS Doom 2 and ported a Chocolate Doom to it. And then Chocolate Heretic. Attention: This does only work on the original DOS Doom2 version, no GZDoom or other source ports. This is a good thing as you don’t want code execution exploit on modern systems. People would abuse it to spread malicious code. DOS version is available on Steam and you can use DosBox emulator to run it.
You can see the process the author used to create this in the video below. The code is available on GitHub.
