Chernobyl Simulator
Chernobyl Simulator is a port of the simulation game Chernobyl: The Legacy
Continues
to modern 64-bit Windows. The original version was released by Gatekeeper
Technology Group in 1998 for Windows 3.1 and Windows 95.
Your goal is to safely operate the Chernobyl Nuclear Power Plant Unit 3, fixing
any malfunctions that arise, while keeping the whole operation on a tight
budget. You will learn about RBMK reactors and nuclear power plants in general.
The manual remains the primary resource to learn how to play, but you may want
to read “Getting started with Chernobyl
Simulator” for
an introduction to the game.

Releases
To run the game, use the shortcuts added by the installer to the Windows Start
Menu:

There are 2 versions of the manual:
- Scan of the copy distributed with the original game.
- Conversion of an original WordPerfect draft to PDF.
The scan is monochrome with a lower text quality, but the converted draft
content may slightly differ from the final version.
I had to make slight changes to the original game to make it work under
otvdm. For convenience, I also added the following features to the menu
Extras:
- Pause: pauses the simulation.
- Malfunctions: toggles malfunctions on/off.
- Fuel: freezes fuel burnup.
- Videos: blocks video popups.
Hacking
The supporting programs (RXMODEL, ICSELECT, etc.) are Visual Basic 3.0
executables. They were extracted using DoDi’s VB3 Decompiler. If you want to
modify and recompile them, you can follow these steps:
-
Download the Microsoft Visual Basic 3 Professional installation disks from
WinWorldPC.
-
Extract all disk images into separate directories named disks1, disks2,
disks3, etc.
-
Open the setup disk (disks1/setup.exe) through otvdmw.exe installed in
C:\Chrnobyl\otvdm\ to start the installation.
-
After installation, launch the Visual Basic IDE by opening C:\VB\VB.exe
through otvdmw.exe.
-
Open one of the project files (RXMODEL, ICSELECT, etc.) and make your
changes.
-
Compile to an .exe inside C:\Chrnobyl\ and test by running it through
otvdmw.exe.
