Here's vgmuseum.com's presentation of the SNES ending of Ryuuko no Ken / Art of Fighting:

Nintendo of America made a number of changes in their translation of the original Super Famicom ending text, in order to soften it up a bit so as not to tarnish the kid-friendly image they'd been promoting to their user-base's parents. In the SF version, the man who killed (not "defeated") Takuma's wife, Ronette (I think this spelling is probably more correct), is not referred to as a "criminal." The Japanese text refers to this person with the word "yatsu" (an informal term for "person," somewhat similar to the casual use of the word "guy" in English). Further, the Japanese version describes this individual as the one who "accidentally caused her death." Not, therefore, an intentional act of murder, but enough to cause Takuma to abandon his children in order to dedicate himself to searching out and punishing this person. Also, the SNES uses of the word "defeat" in reference to Jeff Bogard seem to be intentional mistranslations -- the Japanese version uses the word "shimatsu," meaning "to dispose of."
While the idea itself is kinda cool (while Ryo and Robert race around Southtown tracking down the kidnapped Yuri, Takuma is in another part of the city killing Jeff Bogard against his will), it flies in the face of the ending sequences from AoF2, as has been previously pointed out in this thread. It also fails to jive with the chronology of the AoF and FF events (AoF and AoF2 are supposed to take place in 1978 and 1979, while FF is set in 1991 with Jeff's death set 10 years earlier, in 1981). According to Denpa Shinbunsha's "All About Series Vol. 4: All About Ryuuko no Ken 2," due to the discrepancies between the SNES AoF Ending and the storyline of AoF2, the events depicted in the SNES Ending are recognized as an "Original Story" that applies only to the SNES version of the game -- it has no bearing on the proper storyline of the AoF series, as depicted in the original NEO-GEO versions of the games. The official version of things is: Geese killed Jeff.
Fatal Fury Wild Ambition is supposed to be a retelling of the story told in Garou Densetsu / Fatal Fury. The Mr. Karate of this game is indeed Ryo Sakazaki, having taken on his father's old alias as he makes his move to take Geese Howard down once and for all -- and finally appearing alongside the Bogard brothers with the appropriate difference in age (Bogards in their very early 20s, Ryo in his mid-30s).

I always liked the ideas presented in the SNES AoF Ending. It made sense that Geese would use another powerful martial artist to do his dirty work, keeping Geese's hands clean socially/legally and eliminating the concern of defeat at Jeff's hands (which was certainly a danger, based on Geese's recognition of the threat Jeff posed). It also would have allowed for the creation of an interesting dynamic between the Bogard brothers and the Sakazaki family -- yes, Ryo's father killed Terry's father, but only to protect the life of his daughter, Yuri. It could have been a source of some marvelous tension between the two families -- and certainly would've been a better plotline for the AoF anime TV special than the smeg they ended up using for that stinker of a film. I just wish that SNK had made the KOF versions of the AoF cast 15 years older than they did -- just to preserve the age difference between them and the FF characters.
