Did you know that a DS Linux port exists? The retail models have just 4MB of RAM.

Apparently there was a "3in1" device for the DS that added 16MB of RAM.
Days, in my case. Hours, actually, is my record.
Yes, but it was severely limited in what could be done and swap wasn't supported. Swap would greatly increase what can be done on the 3DS. Plus, that port only ran in DSi mode or on flashcarts that add RAM, so it was actually running on 16MB, not 4MB.
All the devices it has a release for on the old page have RAM expansions (or only work in DSi mode)
"The DS only has 4MB of RAM which severely limits how much you can do with DSLinux. Thanks to the work of Amadeus and many others, the DLDI Build will now detect and enable the GBA RAM automatically on most Slot-2 cards that have built-in RAM. If you do not have a RAM extension you may experience crashes and "out of memory" errors when running most of the applications."

Huh. Alright, I admit defeat, you win. However, Linux, I WILL NEVER LET YOU BEAT ME SO HELP ME LINUS
If this actually works it would be cool to get a Dingux port. I'm pretty sure most of the devices that run Dingux are less powerful than the 3ds and they also don't have gpu support (they use the framebuffer driver). I think it would work really well. (GBA emulation on dingux would be really cool.)
Silent rage, if you must know... trying to figure out how the hell the singular driver should be structured.
I've been working on it for a while, ported all of xerpi's tree to 4.20 (latest when I started) and got some stuff like SD read/write working, as well as other devices.
If you want you can take a look at my code (be warned, it's very rough and unfinished, but it works and is pretty stable)

This is basically what I was trying to do. THANK FUCK you managed this, I was getting worried I couldn't do it xD
(Drivers are hard...)
I found the biggest problem to be a lack of up to date sample drivers, the LDD3 is horribly out of date and most examples don't even compile.
Another big problem is choosing the right interface - using the block layer directly isn't as efficient as using the MMC cobtroller layer, but on the other hand passing each register to be written or read to the ARM9 would be unbearably slow.
If anyone wants to help out with the repo, feel free to open a PR
Wow, this is very impressive. This is actually useable now! (Plus, it's on Linux 4.20! Blaze it.)
The real problem is that programmers don't know the value of a megabyte - 32 MB for a (non general purpose) system designed in 1999 wasn't top end but definitely usable, while the official PS2 Linux (which depending on who you ask for, was a tax elusion scheme, a PR boosting stunt, or a gimmick) released 3-5 years later would feature software providing acceptable performance by then's standards
Whereas less than a decade ago, the early versions of Gnome 3 made one of the heaviest desktop environments with the least user-accessible customization!!
Luckily most Linux systems
(* comparison cherry picked to rant at modern
So apparently devkitPro drank the coolaid and wants to force me to use pacman to download it. Can you send me a build of your arm9linuxfw?

Because I already was forced to install apt on Fedora for a different thing, and forcing this is bullshit.
No, my version of arm9linuxfw is tightly coupled to my kernel tree so you have to compile the full thing in one go.
The entire Linux package? Well... shit. I could send you the config files for generation, I guess...

Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.+1 -

@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.+1 -

They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

Nothing special about it other than it's more comfortable than the Lite+1

@SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme -

A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."+1 -

anyways, we need to re-normalize physical media+1
if i didn't want my games to be permanent, then i'd rent them -
@
BigOnYa:
Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

@BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.
The issue is DRM -
@
cearp:
You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60
