Open BK2 File

A BK2 file is a file format associated with specific applications and, in some cases, can possess multiple uses depending on the associated program. This article will explore the various formats and ways to open or utilize these files, describing how each use differs from each other.

Use with BizHawk

The BK2 file extension is used as a movie file with the BizHawk emulator, a multi-platform emulator with built-in TAS (Tool-Assisted Speedrun) recording and playback features. The BK2 files are created while recording game inputs during a TAS run across various gaming platforms, such as the Nintendo Entertainment System, the Super Nintendo Entertainment System, and others.

To open and utilize a BK2 file for Tool-Assisted Speedruns, you will need the BizHawk emulator installed on your computer. Follow these easy steps to utilize a BK2 file:

  1. Download the latest version of BizHawk from its website or GitHub repository and install it on your system.
  2. Launch BizHawk and open the game for which the TAS run is made.
  3. Click "Open" in the "TAStudio" menu and navigate to the location of your BK2 file.
  4. Select the BK2 file and open it to play the recorded TAS run.

Use with Kerbal Space Program

The BK2 file extension is also used for backup files created by Kerbal Space Program (KSP), a space flight simulation game. These backup files are not movie files like with the BizHawk emulator but instead contain saved game data. They help players to preserve their game progress in KSP, and in case of an error, players can restore their game to a previous point in time by using these backups.

To open and restore a BK2 file in Kerbal Space Program, follow these steps:

  1. Navigate to your KSP saved game folder. Typically, the location is "Kerbal Space Program > saves > [Your Save Name]".
  2. Find the ".sfs" file in the folder, which is the main save file for the game, and make a copy of it outside the folder in case the process doesn't work as intended.
  3. Rename the ".bk2" file so that it has the ".sfs" extension.
  4. Replace the old ".sfs" file with the renamed backup file and start the game.

BK2 File Important Information

When working with BK2 files, it is essential to know which application the file is associated with, as the content and use differ significantly. For example, a BK2 file related to BizHawk will not work with Kerbal Space Program and vice versa. Remember to have the appropriate software installed to open or utilize the BK2 files accurately.

In summary, the BK2 file extension has multiple uses, and understanding which application it is associated with is crucial. This article provided an overview of the usage, opening, and using BK2 files related to both BizHawk and Kerbal Space Program.
