About

Nitemare 3D is a horror-themed first-person shooter released by Gray Design Associates in 1994 for MS-DOS and Windows 3.x. OpenNitemare3D is a C# reimplementation of Nitemare 3D using SFML that loads the original bitmaps and maps and plays MIDI music and Windows sound effects. It is only partly functional, and development is moving to a C rewrite for performance.

Getting started

Build in VS Code with the .NET SDK and SFML, then copy the original game's data files into the build's data folder (the author recommends taking the sound data file from the newer Windows release). Most menu options crash the game; only New Game and the sound editor work.

Known issues & limitations

audio: Most menu options will crash the game; only new game and sound editor are functional.
audio: DOS sound file support is incomplete; most DOS SFX sound garbled.

Requires original assets. Requires original game files including SND.DAT, UIF.DAT, MAP.1, IMG.1, and GAME.PAL.

Additional notes

Audio: Most DOS sound effects play back garbled; full DOS sound support is still in progress.
