Parameter Adjustment and Retrieval
Open video games allow you to adjust and retrieve parameters without writing code.
Adjustment
Parameter adjustment allows for easy adjustment of game difficulty and specifications to suit the experimental environment and other circumstances. In addition to numerical adjustments, visual adjustments can also be made by replacing images.

Retrieval
It is possible to obtain internal game data that cannot be ascertained by observation alone. It can be used for evaluation and analysis of game experience and controller devices.
