ACTBIN files store game data specifically for ACTKOOL, a line of devices by Datel. These files, predominantly identified as Action Replay save files, contain saved game states, allowing users to store and resume their progress in various games. ACTBIN files are primarily utilized by Action Replay devices, which are designed to modify or enhance gameplay through cheat codes and other features.

This file format is classified as Game Data.

The first characters in a file identify the file format, for example, HTML files start with the bytes <html>.
