Thats a rather vague question
As you have normal TTX2 games, and you have deluxe titles,
such as,
tableflip game, its purely in japnease
But if we are talking stick and buttons game, every single one of them is either in english, or no english is required to play them, or can be forced into English via test menu / external means
and the deluxe games, your mileage my vary, and we dont even have a full list of games that truely exist, so providing any type of list of what is and isnt english is going to be nearly impossible
