One of the most heated debates among RM/MM fans is the "R&F is RM9" hoopla. Although Capcom classifies RM&F as a side story, some people just won't give in. Tonight, I shall put an end to the argument.
Ripped straight from RM&F's Rom image, you can see that the game's file name is "ROCK 8.5" (Rockman 8.5)
There you have it, RM&F is not RM9. End of story.
