Abstract: A system may validate execution of a video game to identify the existence of a coding error or of cheating by a video game player. The system can record action events performed by a video game within an action event log, which may be provided to a validation system that can repeat the action events identified in the action event log. By comparing a state of the video game with a state generated by the validation system responsive to repeating the action events, the system can determine whether a coding error exists or if a user is cheating (e.g., using cheat software) when playing the video game. Further, the system can use isomorphic code enabling the validation system to repeat the action events independent of the system hosting the video game. Thus, the system hosting the video game may continue to execute the video game while validation occurs.
