I wish they had mentioned it in R20. They had those old Nintendo Power scans of mine and the American cartoon series; why not go for the good stuff? RM Strategy has a few neat designs even if the game is incomplete.
As for the Japanese game canon, none of the licenced stuff counts. We had a whole discussion about canon I won't go into again. But, to summ up licenced games:
Game Gear Megaman
Megaman 2 and 3 Tiger
ALL the Taiwan-only games
Rockman and Forte WS
Oddly, R&F WS was made into canon, wasn't it? So, maybe if Capcom Japan ever bothered to look up some of these other games, just maybe, they'd be made into canon.
I can just picture Torchman looking up and wishing on a star for that to happen right now. You know, before he'd crushed by a giant meteor and all.
