Hardware Nintendo DSi firmware on Nintendo 3DS?!

[Devide6754]

Guys, is it possible to get a Nintendo DSi firmware on my 3DS?

What seems to be the problem? The 3DS has several firmwares, one of which is the DS(i) mode.

To my knowledge it's not possible due to TWL_FIRM containing a modified version of the DSi secondary boot code, and probably some other hardware differences.

But don't take my word for it, it's just what I remember from the top of my head, and might be the complete opposite.

Lol, you checked, too? Of course you would.

Yay, he's not going to find the original DSi BIOS in the TWL_FIRM.

• How would I go about dumping Nintendo DSi BIOS files from my 3DS, for use in no$gba?

The 3DS is missing a few key files on TWLN Partition that is needed for DSi System Menu. At one point I got those files installed and almost got DSi System Menu to boot. I might be able to launch it via Unlaunch, however Unlaunch doesn't recognize or is unable to init the Wifi on 3DS and doesn't let me proceed any further. That aside System Menu either white screens or shows an error screen when I try to force it.

The issue is the dev launcher/boot2 combination that TWL_FIRM uses results in the stage2 SRL I use thinking the console is a HNAA region console. Thus I can't use a HNAE (USA region) retail DSi Launcher SRL without modifying it's header and System Menu doesn't like to run with a modified header so no go on that.

So yeah don't get your hopes up on that.

As for getting the DSi bios files. (For No$GBA?). You are better off dumping those off a real DSi. I think the ones the 3DS has are incomplete. Especially the DS bios files. You won't be able to boot DS firmware menu with the dumps from 3DS (or a DSi for that matter). For DS firmware files it's best to get those off a real DS/DS Lite.

I vaguely remember something.

Checking 3dbrew and dsibrew, I concluded that there is indeed some sort of SRL, and the secondary bootloader is also right next to it in TwlBg. You have to decompress code.bin from TwlBg to find both.

2nd bootloader MD5 ABB992EB70B7915A2C94997B3F6B169D (or if you count the weird date string too then 8313D76C56F60FF31F354C0F0583EC96)
The weird SRL's MD5 is 25D8E41763EC595E747E0397982A6683

I would really like to run the DSi Menu on my 3DS... I have all the required files, could it be done by swapping the DS Download Play in TWLNAND with the DSi Home Menu and also copying everything else?

just run twilight menu++. it's the look and feel of the dsi if you choose that theme.
