I gotta wonder, everyone knows the Play Novel's Boy Scenario is lost media, but like... has anyone just tried emailing Konami Japan's customer service about it?
That seems like a really dumb idea, but Konami probably does still have the scenario on file and they want to appeal to the good graces of fans currently, and I have not seen anyone even remotely consider this pretty basic idea.
