I'm at such a loss. Both controllers gained the exact same issue at the exact same time. The console seems to be running fine. PS4 controllers are expensive. ($60-$70 price range per controller) and I'd rather not replace immediately if there's an alternative solution.
There is a decent DS emulator on the app store called Drastic. Even on my lower end phone, it was running games phenomenally. It's a $4.99 payment, but honestly one of the best emulators I had ever come across. Might be worth looking into if you want. Otherwise, this laptop was left to us by another family member who was upgrading. My mother didn't want it (she has her own computer). It allows me full use.
My neighbor paid $300 for a physical copy of Thousand Year Door. I last played it next door...around 2021, I estimate. The 'highs' exceeded the original N64 version. Chapter 3 and 6 were the highlights. The 'lows' are worse than the N64 version. Chapter 7 in particular felt like a slog. Overall, my preference of 64 comes down to level design. Thousand Year Door often felt like going down one long path followed by a dungeon. (Chapter 1, 4, 5, 7) all fell into this.
I recently finished Mario Kart 8. Obtained 3 stars on all cups including 200 CC. I went online after and still got walloped. Guess it didn't improve my skill much, but I got some neat bonus title screens.
