eCrew Development Program is a Nintendo DS title designed to train McDonald's Japan staff. It was never made available to the general public and required a password to access. Regarded as lost media for years, the game resurfaced when its ROM was uploaded to the Internet Archive.
In 2010, McDonald's Japan partnered with Nintendo to develop the eCrew Development Program, a Nintendo DS game aimed at training new staff. The game garnered some media attention, but it was exclusively distributed to McDonald's Japan employees and required a personalized password to access. The game guides players through the process of cooking and serving different McDonald's menu items and performing other duties within the restaurant. It was utilized as a training tool for new employees. The game features multiple modes, including simulations of food preparation and customer service. It also includes quizzes, individual profiles for employees and managers, and performance tracking.
