Homebrew DS emulator

[randomdev]

Hi everyone !
I have an homebrew idea, is it possible to program a Nintendo DS emulator like blargsnes or gameyob for the 3DS with ninjhax ??
Thanks !!

The 3DS can play DS games natively.

Unless you mean a way to play ROMs from SD.

I know ^^ but my question is : can we emulated "r4" with ninjhax ? This is for users who don't have flashcard

So yes , load roms from SD ^^

Nice idea, I also wonder if it's doable.

 

[hippy dave]

An actual DS emulator, not possible/realistic. A way to run DS roms without a flashcard, might be doable but nobody's figured it out yet.

Buy a R4i SDHC Dual core the price is like $8 and it work on 9.8

Booting ROMS from the SD would be sweet but I doubt it'll ever work.
Unless SD access will be figured out in DS mode, I can't really see it happening

DSi mode?? Like SudokuHAX

It's been attempted, but a number of DS roms will fill up the DSi NAND section beyond capacity, even when trimmed. They also don't run and have boatloads of compatibility issues.

There is zero point in an emulator when the 3DS contains native hardware and firmware modes exclusively designed to play DS(i) games.

As for adapting those firmware modes to read software from SD instead of a flashcard, it could be feasible but I don't know if it's physically possible or enough interest. With DS flashcarts as cheap and accessible as they are, there isn't much reason to.

 

[sweis12]

Yeah, honestly you can just spend like 10 dollars on a cheap flashcart if you just wanna play DS games. Or, you could just spend $40 on a DSTwo and have support for many emulators, like NES, SNES, GBA, and even an old Mac emulator,but I think yo could do most of that with the 3ds homebrew.

And if someone found the way to convert .nds in .cia?
Something like a NDS converter...maybe someone can create a thing wich "emulate" a 3ds game but in substance it runs a NDS Game...
Like r4s, wich use other NDS cartridge firms in their bootloader.
In Dsi case, r4 can be runned by this one because the console think about a real game but in substance you aren't running a real game. You are running r4.

Save States? Fast Forward? Cheats (if that's your thing?). Theoretically, unlike most emulators, this shouldn't have a huge amount of overhead, as instructions can just be passed straight through, and will act kinda like virtualbox does for running an older OS in windows/linux. In practice, i'm sure that there'd be more work required though.

I don't know exactly how the TWL_FIRM mode works internally, but each of those could be possible. Depends on the hardware.
You can use cheats on original hardware anyway.

That's not emulation, that's virtualization and there is a critical difference.
I'm pretty sure the 3DS contains an ARM9 and ARM7 CPU core for natively playing DS games (the ARM7 being the GBA's CPU also, leading to the possibility of AGB_FIRM as well). It's hardly emulation when you build the old silicon into the system too.

It would be possible to run ds roms from sd but would require a very extensive and difficult TWL firm mod. So not likely anyone will go to the trouble.

You might get a frame every few minutes or so.

There is a converter for .nds to .cia, but it only works with dsi roms, which are injected into an already existing cia file.

So only few games can work...

thanks but my question is not to know how to run DS roms with flahcard but WITHOUT flashcard and with the 3DS (Ninjhax for example)

Basically, you can't. Only a few cases that actually work as already stated above.
