Gaming colossus Nintendo and fast food giant McDonald's have long been business partners in different ways the world over, whether that means setting up consoles for public use, having been one of the biggest and best known Nintendo Zone service providers even before they were a thing in The West, occasionally bundling Nintendo gadgets with Happy Meals and... ordering a custom limited edition of the DSi, intended for use with their own "game" card containing a training course for their staff.
While this latter fact has long been known by most hardcore gaming historians and collectors, the eCDP Kurutore (standing for "eCrew Development Program - Crew Training") was still a mystery for most people, being undumped and furthermore requiring an user account to be downloaded from a now defunct server.
That is, until yesterday, when the successful effort by ObscureGamers members code1038 and ItsMeMario to crack the password on a save file with some user profiles already present met Nick Robinson's financial effort to buy, import, dump, and publish a ROM of his copy.
