Sylvanian Families: Otogi no Kuni no Pendant (Epoch, 1999)
The first in a series of games starring the daughter of the rabbit family in an animal village where everyone is happy. The intros to these games are extremely long and incredibly boring, so I didn't bother to read much of them. This one is an adventure game, and it looks like there might be farming elements in it later.
Sylvanian Families 2: Irozuku Mori no Fantasy (Epoch, 2000)
The plot here seems to be about a ghost flower stealing color from the world, but apparently it's only some parts of it because there's plenty of color in this screenshot. The GBC seems like an odd console to do the whole black and white world thing anyway. Also, the rabbit family's garden is to the side of their house instead of behind it now.
Sylvanian Families 3: Hoshi Furu Yoru no Sunadokei (Epoch, 2001)
You play as a cat this time. I think it's a cat, anyway. This has the best music of the three main games, but also the most interminable opening sequence. It doesn't really matter how that makes it rank in the series, because I'm not coming back to any of them.
Sylvanian Melody: Mori no Nakama to Odori Mashi! (Natsume/Epoch, 2000)
It looks like a rhythm game, except that you can just freely bang on the drums however you want. There are no required inputs and it doesn't matter if your cacophony has anything to do with the music. This game is pointless.
Tabaluga (NEON Software GmbH/Infogrames, 1999)
A crappy German adventure game in which B is a dedicated "puff up your chest and stand still button". That is, unless you were already holding another button, in which case it just makes all the other buttons do nothing until you let go. That's fun. Also, water kills you.
Taisen Tsume Shogi (Athena, 2000)
A collection of shogi puzzles. I actually do vaguely know how to play shogi, unlike mahjong, but I don't know it nearly well enough to be doing puzzles. It has nice music, but the graphics are pretty crap.
Tales of Phantasia: Narikiri Dungeon (Alfa System/Namco, 2000)
A sequel to Tales of Phantasia that, despite a PSP remake, still hasn't released outside of Japan. It seems to focus on two twins who can turn into anything they can cosplay as, which sounds vaguely like Final Fantasy X-2. And for that reason, I'm out. Also, the music is surprisingly all over the place considering Sakuraba is an established composer, but I suppose this was 21 years ago.
Tanimura Hitoshi Ryuu Pachinko Kouryaku Daisakusen: Don Quijote ga Iku (Atlus, 2000)
The Don Quijote referenced here is the Japanese everything store, not the book by Cervantes. That said, I have no idea what this has to do with the store, since their mascot is a penguin-thing and they don't run pachinko parlors. My best guess is that either this Doraemon knockoff character was their mascot in 2000, or they had a brief entry into pachinko.
Tarzan (Digital Eclipse/Activision, 2000)
A licensed platformer that controls pretty terribly. Really, the reason to remember this one is the embarrassingly terrible version of "Strangers Like Me" that they tried to put as the main menu and level select music. The cart apparently only had the space for the first five seconds of the song, and even those are distorted almost beyond recognition.
Tasmanian Devil: Munching Madness (M4 Limited/Sunsoft, 1999)
A top down game where Taz needs to collect medallions and eat food in order to rescue some wolf I've never heard of, who has been taken to Las Vegas. They implemented the cartoon dizziness effect that happens whenever Taz crashes into something by making the screen shake like there's a major earthquake happening. That wasn't a good idea.
Taxi 2 and Taxi 3 (Visual Impact/Ubisoft, 2000 and 2002)
I'm clumping these together because they're the same game. You drive this taxi Outrun-style and try not to hit cars or obstacles on the side of the road. Gas canisters spawn along the way to keep you going, and when you reach the red arrow on the course line you need to stop or you'll get a game over. I've played this before, but I obviously didn't have a France-exclusive GBC cart as a kid, so it must have been reimplemented as a Flash game somewhere.
