On Crunchyroll, they sometimes have closed-captioning for dubs, and then they match.
Occasionally they’ll have either dubs, or subs (as in you can’t turn on subs when you’re listening to English).
And sometimes they have both, in which case you’ll get the classic mismatch.



Nah, you just need one controller per type. There are probably some more common types you could focus on.
I miss the times when you could just scavenge 18650s out of anything from laptops to ebikes. I built a home battery system out of those.
