Is there any way to play NDS games on a TV? And if so, how do I get started?

[Lazuli_Cookie]

I would like to play NDS games on a TV, but I'm not sure how to get started. If anybody knows how, please reply!

Nintendo intended this, but it was scrapped due to problems. However, I think the stuff needed is still built into the system.

Official methods. None if you were hoping for a modern equivalent to the super gameboy , some of the N64 stuff with GB/GBC carts or gb player https://gc-forever.com/wiki/index.php?title=Game_Boy_Interface .
Some DS games have since received "official" emulated versions but we will cover emulation shortly.
I believe some of the dev kits for the DS (and later devices) have video out options but not all do (some were basically flash carts, and indeed we saw various devs appear here over the years looking to find flash carts to augment their team), they appear from time to time but hope your wallet is fat, your finger quick and your tolerance for annoyance is similarly up there.

Unoffically. There are a few more options here.
At present I don't think we have any kind of hardware recreations a la the https://gbatemp.net/review/analogue-pocket-gb-gbc-and-gba-handheld-fpga-based-player.2081/ I recently reviewed (it only goes up to GBA, DS is not impossible with its specs but it would be a stretch) and nothing similarly seems available for https://mister-devel.github.io/MkDocs_MiSTer/cores/console/
Nor are there things like the unofficial emulator-dumper things we have since seen a few of for the SNES, N64 and such like.

Emulation. Get laptop, raspberry pi, console suitably hacked and emulator has long been an option, and runs whatever controllers you like (or the console supports). The trouble might well be people wanting to do things with official carts.
There are hardware tools that will readily dump and restore saves and ROMs, they got quite popular a few years ago though the ROM aspect can be harder/was more of an unofficial function. There are also methods using a DS and wifi to send it back but that will best benefit from a GBA slot cart with relevant hacks, wifi is annoying with the DS these days (only WEP or no security, limited number of routers it will work with) though DSi might have some options.
https://gbatemp.net/threads/how-to-dump-your-own-3ds-ds-games-saves.274290/ is a bit old but covers most things here.

Video out options.
While there are no official video outs there are two, maybe three main options

Most would know loopy more for other things on the DS and GBA or for video out options then the hardware capture boards for the 3ds (see Katsukity Nintendo 3DS Capture Card for where most go there, though very hard to find today). There is a vanishingly small option for you to find/make something like it for the DS (though if you are an electrical engineer inclined type there are only a handful of screen protocols and modern programmable chips are far nicer than the ones used on the device above).

More recently it was discovered that the DS lite was possibly intended to have TV out features at some point

Fairly simple as these things go actually -- it is not quite an unpopulated header but not so very far off.

The 3ds was managed to be able to stream useful video out over wifi at a rate that makes sense for videos, not perhaps as nice as the hardware methods. Not sure what became of DS options in this though.

Officially then a lot of video capture happened via emulators and we saw a few access media review sites over the years have things that were little more than cameras attached to a suitably shaped box (gamespot having some appear in various round table discussion shots).


Short version.
Figure out a way to dump saves if you need that and use a PC emulator -- they have nice savestates, slow motion modes (though you can kind of do this in DS hardware with cheats), fast motion (can't do it sensibly in hardware), any controller you like, high resolution modes for 3d (can sort of do things like this for the DSi), capture video trivially, use very complicated cheats (desmume supporting all the nice Lua stuff), turbo buttons/macros and plenty more besides.
