I don't think they're all worth searching out, but like The Great Battle earlier, there are a
lot of games on the Super Famicom associated with Compatiheroes and Super Robot Wars. If nothing else, they're interesting for just being prolific early crossover games:
Battle Robot Retsuden. This one is by Winkysoft, the developers of the original Super Robot Wars. It's a very similar turn based strategy game - immediately visible differences are that it only features Super Robot series, it uses close-ups of the robots instead of SD proportions, it has an isometric view, and it's placed on a hex grid instead of a square grid.
Battle Commander. This is by Arc System Works. It's a real time strategy game rather than turn based. I haven't really explored it, but it looks like there's training and equipment involved.
Battle Pinball.
Battle Pachinko.
Battle Dodgeball. Notice the proud claim of this having RPG mode. Camelot, eat your heart out.
Battle Dodgeball 2. Pretty sure this one is canon. There's a third one too, although that's way later on the PSP.
Battle Soccer. Godzilla's in this one!
Battle Soccer 2.
Battle Racers. This uses Mode7 a la Super Mario Kart or F-Zero.
Hero Senki: Project Olympus. This is a turn based RPG with a bit of a comedy tone. This is also by Winkysoft, and it's the first to establish that Super Robot Wars canon is a multiverse.
Gaia Saver. This is a turn based RPG, essentially a sequel to Hero Senki, although this one's by Arc System Works.
Super Tekyuu Fight. It's kind of an oldschool arcade title; think Bomberman. You fight enemies with an eye ball on a chain and there are giant bosses. It's actually the sequel to a platformer on the Gameboy.
Just to reiterate, this list isn't including the Super Robot Wars or Great Battle series, both of which ran for around five titles on the Super Famicom.
