Homebrew Open source 3DS firmware?

[Deleted member 446461]

I do know such thing as Luma3DS exists, but I am not talking about the overlay CFW. I am talking about replacing the 3DS's firmware with an open-source one.

Does not exist

Is there something you would hope to do with such firmware that you wouldn't be able to do otherwise?

That's an enormous job, but it has been completed for some system modules though.

A complete rewrite of the firmware almost certainly will never happen.

Well the 300 title limit is bullshit, the gift-wrapping of new apps is unnecessary bullshit, and I feel like the entire 3DS "home screen menu" could just be replaced with a no-frills text menu, maybe with touch controls on the bottom screen.

To get around the 300 limit we have 3dsbank

That's still just a band-aid, not a full solution. Kind of like adding an SD card to the Wii for more channel space, instead of having infinite channel space using UNEED/SNEEK.

While I agree with you can't you just like install less games? Surely you don't play all 300.

At that point you'd simply be ignoring the problem.

Yeah, the problem that people are addicted to installing games and not playing them

No, the problem is the title limit. Blame the software, not the user.

Exactly, artificial limitations set by the OS are just not needed.

 

[Rj.MoG]

Bruh I can’t even name 300 titles. I can’t imagine how long your Home Screen takes to load that data off the 3DS SD Bus

Not so "in the know" about these things but what are the uses of these tools?

The context of the... documentation is a bit confusing. Injector suggest system patches like region free games that CFW like luma does already. the agb firm loads gba roms without home menu, but still uses nintendo's emulator that isn't compatible with most games like homebrew emulators are. I have no clue what 3ds pxi means or what patching arm11 does. Amiibo emulator is interesting, especially for 3DS systems without nfc amiibo support.

Pardon my lack of understanding, I just would like to better understand. One useful thing I can think of right now is booting directly into NDS carts with power on.

Many of such people are looking for a way to install hundreds of games to sell the console "full of games", they don't care about playing them all.

im pretty sure "3DS WITH TOP 300 GAMES " still makes a fairly complelling listing for anyone into that sort of thing (mostly clueless parents)

I don't know what you mean. VC GBA injects aren't really "emulation"; it executes the ARM code natively on the 3DS CPU. And it's more compatible than GBARunner2, isn't it? Even if it's not more compatible than mGBA, it's certainly faster.

I have no clue what 3ds pxi means or what patching arm11 does.

Aye, I'm not clear on that either.

Those are just open source re-implementations of select system modules (and agb firm) that add a few features over their stock versions. Their readmes will have more details on what those features are. Maybe.

From what I can tell 99.9% of people don't care about the 300 limit because no one in there right mind will even install 300 games, if you need 300 games because you have that much time on your hands I suggest you go outside and put the 3ds down for a while, its not healthy.

Text based ui, you for real? Couldn't think of anything worse.

What YOU want is something only YOU need. Therefore no one else will be willing to make what you want.

Device is predominantly used to play games and it does that already, very well.

Either code your own or you could pay someone to do it for you as long as there skilled enough.

Re-implementing firmware as open source is a lot of work.

It has taken me 2.5 years to re-implement just the boot package part of the firmware for the Nintendo Switch -- someone of my skill level would probably take ~10-13 years to implement the 3DS operating system as open source doing it at about the same level of work that I spend on Atmosphere.

It would surprise me a lot if anybody wanted to spend that much time...but I am doing the same thing for the Switch, so I definitely support anyone aiming to do that.

For what it's worth, once the Switch is less alive I intend to go back and complete Atmosphere-3DS (Kernel9 re-implementation, but given I've successfully implemented KernelNX it'll probably be Kernel9/Kernel11).
