What is act file?

File used by DS Game Maker, an application used to create Nintendo DS games; contains a game action written in a proprietary DS Game Maker language; used for displaying graphics, playing sounds, creating transitions, and controlling game logic, as well as other actions. Custom actions can be created from templates provided in the DS Game Maker Action Editor interface. ACT files are stored in the Actions directory of a DS Game Maker installation. ACT files are saved with a corresponding .ACTX file, which contains a description for the action.
