Getting Noctis IV Plus to run on modern computers

Noctis IV was made for MS-DOS and early Windows versions that still supported 16-bit MS-DOS executables natively, and as such, you'll need to be able to run DOS on your computer. To run Noctis IV plus on modern computers, you have three main options, in order of simplest to most complicated to setup:

1. DOSBox-X (all modern operating systems)
2. DOSEMU (Linux only)
3. A FreeDOS or MS-DOS environment running inside of a virtual machine like VirtualBox

DOSBox-X (recommended)

The Launch.bat script lets you run Noctis IV Plus with a simple double-click on Windows systems. It expects DOSBox-X to either be installed in it's default location C:\DOSBox-X\dosbox-x.exe, or installed portably with it's bin folder placed in the main Noctis-IV-Plus folder.

If you are using a system other than Windows, simply run the following command:

dosbox-x -c "mount n '<directory where NIVPlus is installed>'" -c "n:" -c "cd modules" -c "NOCTIS.EXE" -conf dosbox.conf -exit

Other DOS Emulators

Run the following commands in your DOS environment:

cd <directory where NIVPlus is installed>
cd modules
noctis.exe
