There's three SNES games, though! ...well, only one got released in English as a Ranma game, though.
The first game got released in English as Street Combat, then the second one actually got released as Ranma ½: Hard Battle. The third game was never released outside of Japan, though it was planned for release as Ranma ½: Anything Goes Martial Arts, but the company that had the rights to it went out of business before release. A shame, since the third one is supposed to be the best of the bunch by a long shot.
Here are some Classic Game Room/CGRUndertow reviews for them, in order of game release:
Ranma ½: Chounai Gekitouhen
Street Combat (same game as above)
Ranma ½: Hard Battle
Ranma ½: Chougi Ranbuhen
I've been meaning to get the last one for a while, but haven't gotten around to it. I played them years ago, and it's the only one I remember really liking.
There was also an RPG and a puzzle game. Neither got released outside of Japan, but the RPG has a fan-translation.
I saw the same pictures there recently, so I figured you got them from there. Maybe I should go "Like" the page...I looked into it randomly after some other Sailor Moon page(s) shared stuff from them. I'm not normally into memes, though.
