Is it a coincidence that the Nintendo 3DS' GPU is called the "PICA200" (i.e.: 'Pikachu-hundred')?
Yes. It was created by an unrelated hardware company 6 years before the 3DS was announced.

https://en.wikipedia.org/wiki/PICA200

Perhaps it influenced the Nintendo hardware team to choose it
it was an economy/efficiency choice.

it was either an American Nvidia model or a Japanese DMP.

A high res camera wasn't needed, nor were the programmable shaders that Tegra 2 offered -- Nintendo decided to go with the chip that ran cooler, longer, was produced with a local IP, and came with tessellation for almost-free.

You forgot the most important point: it also sounded like Pikachu!
It's not Pikachu related. My guess is that PIC stands for picture. PICA200 was a GPU designed for embedded devices, most notably used by 3DS, but there are other devices that have used it.
It's weird to see this on front page now, because I submit it 2 days ago.

If you are interested in the chronicle of hacking the 3ds, there is a more detailed thread: https://gbatemp.net/threads/3ds-hacking-scene-history.443396...

Here is why:

Moderators and a small number of reviewers go through old submissions looking for articles that are in the spirit of the site—gratifying intellectual curiosity—and which seem like they might interest the community. These get put into a hopper from which software randomly picks one every so often and lobs it randomly onto the lower part of the front page. If it interests the community, it gets upvoted and discussed; if not, it falls off.

Thank you. HN is more than I think!
Last year I bought two Nintendo "DS Lite" and one Nintendo "New 3DS". The DS Lite were a little small for my hands, and that's how I ended up buying the "New 3DS". The "New 3DS" fit my hands nicely and had a comfortable screen size. I bought all of these things second hand off of the equivalent of eBay/Craigs List in my country. I also picked up some DS games and a couple of 3DS games for free.

My original plan was to have a go at homebrew for DS, which is why I bought the DS Lites in the first hand.

I ended up not doing any homebrew for any of them, but had fun playing the games that I got for them.

After having played all the games that were worth playing I sold all of it. Ended up even making a buck or two. Not like profitable business basis kind of extra money but just a little more than I had paid originally, because I'd picked cheap ones when I bought and I also had the games I had gotten for free which I included when selling them again.

I did the same to pick up DS lite in 2016 but not like you that I didn't want projects, just some fun. I never played them when they were released when I was at Univ nor the other consoles. I'm a big Castlevania fan but only played torrented copies on emulators.

The feel of Lite and the optimised gameplay experience stunned me. It reminds me of the old Gameboy feeling. So much fun than any games on PC (control-wise). I quite like the fact that it is compatible with GBA games. And the experience is consistent with native DS games. Best 50 pounds spent on second hand devices.

Is it worth it to buy a 3DS or a Switch Lite? I'm thinking of having one, and buying the Switch is more of a future-proof gadget than N3DS. What are your thoughts about this?
If you are interested in hacking it, definitely a 3DS. It's simple to do in any model and it has a ton of homebrew software. It's doable in the switch but you'd want a unit manufactured before circa Jun 2018 for now, the process is more convoluted and less popular.
I'd recommend you borrow a Switch from your friend for a while. Play Super Mario Odyssey or BOTW and then you can decide whether you want a Switch. Most of us buy Switch for games like that.

As for 3DS, it is dead. Big titles have released or will release their successor on switch. However if you want to play Pokémon, go for a 3DS as their Switch version is really disappointing, and I assume they will keep disappointing.

Personall, the switch is too large for me to want to use it as a portable game player regularly, and the lite doesn't work with a TV, so I didn't consider it. Also, loading times for the Switch seem longer than my DS/2DS, but I haven't measured.

The 3ds line has a large library of fun games, but won't be getting many more at this point. I went with the 'new 2ds', because I don't care about 3d, but I like the clamshell, even if it probably means the hinge will break eventually, like on my DS; the original 2DS just seems unweildy for me.

It used to be somewhat easier, but Nintendo surprisingly released an update last month (despite discontinuing the 3DS last year) that fixed the last exploit.
