Here it is, the first DSi CFW!

Video by Alex S (with TWiLight Menu++ (previously known as DSiMenu++ and SRLoader) installed):


Video by @Apache Thunder (When RocketLauncher was planned for a release. With WarioWare Touched (DSiWare version) installed.):


(NOTE: Since hiyaCFW has been released a few days ago (as of posting this), and no official thread has been made, I decided to go and make it, despite not making the actual patches for it. )

With this CFW, you can run custom DSiWare, alongside region free and 3DS-exclusive DSiWare (WarioWare Touched), on your SD card, via NAND to SD redirection!
You can also run blocked flashcards (such as R4 Ultra).

FAQs
Q: Can I use a custom splash for hiyaCFW?
A: Yes you can. Place it at "sd:/hiya/" and name them "splashtop.bmp" and "splashbottom.bmp". Make sure they're actually saved as .bmp files, with the size of 256x192, with no color space info, and is 16-bit (A1 R5 G5 B5, or X1 R5 G5 B5). .gif files will also work instead of .bmp files.

Then press SELECT and choose DSi Menu.
I remember Robz8 removed it from TWiLightMenu since V7.3.0 due incompatibilities.

My gba is asking for a bios, does anyone know where to find it?

Use google. We do not condone piracy here.

Also, this is irrelevant to HiyaCFW itself

Okay this is just not working for me, I followed the guide so far and everything has went perfectly, HiyaCFW just has been complete *** and refuses to work.

So at first it refused to open because it couldn't locate OSFmount, turns out I had to install v2.0, v3.0 doesn't work for some reason (also tired then upgrading v2.0 to v3.0 but it didn't make difference). Now that I actually get Hiya to open, it now gives me this error:

And yes I've tired everything, different sd cards, formatting it(with windows and other formatting programs), rebooting the system, redownloading hiyacfw, trying the old hiya versions, running the python version instead of the windows one.. nothing has worked so far, and Im out of ideas, so if anyone knows what Im doing wrong please tell me.

This should go in the helper's thread. By any chances are you on Windows 7?

Thanks for your guide, I've finished installing HiyaCFW and TWiLight Menu ++ and it's so good.
But I have two questions.

Q1:The real system of my DSi is 1.4J, and the HiyaCFW DSi system is also 1.4J. Could the HiyaCFW DSi system update to the newest 1.4.5J? I try to update but it happens an error message (black background and white word), and I should turn off my DSi. How to fix it?

Q2:I uninstall all the CFW and homebrew from my DSi. I update the real system of my DSi from 1.4J to 1.4.5J before installing the HiyaCFW by the guide. When I finish the HiyaCFW installing and enter it's setting to turn on the wifi, my DSi get the same error message (black background and white word), and I should also turn off my DSi. I can't turn on the wifi on my HiyaCFW DSi system (1.4.5J). How to fix it?

I am debating if I should install a HiyaCFW on my DSi. The main reason is because I have a flashcart that only works on a DS but I would like to use in on my DSi. I tried using TWiLight Menu++ as an alternative but I found it to be too glitchy for my liking. I figured out that if I HiyaCFW, it would allow my flashcard to work but the I only have ONE SD card. So it can't be used for the flashcard and DSi at the same time.

So if I install HiyaCFW, does my DSi need the sd card for it to boot?
And if its not required, will my flashcard still work? (because would be booting from that internal NAND)
Also, is HiyaCFW glitchy? (Just cautious lol)


Thanks for your help!!!

P.S. I know I can buy another SD card or even a compatible flashcard but I want to work with what I have currently have)

Is it normal behaviour, that with latest Unlaunch v1.9 and HiyaCFW on 1.4.5j with 8Gb memcard can't launch the normal DSI homescreen (launcher)? Getting black screen with error (japan) text. Right now i'm using Twilight Menu instead of it.

 

[alivebacon]

My DSi won't boot into the hiya.dsi at all. I've even reinstalled unlaunch to no avail. Scared to use 1.9 as I use 1.4.5E, what's wrong?

 

[Ryccardo]

Yes, it is documented that the official DSi Menu doesn't support more than 2 GB of twlnand (which Hiya "mounts" the SD as)

 

[0-volt]

is very hard. i installed the unlaunch, but i can`t install the hiya.
firmware 1.4.5
is recommended to downgrade to 1.4 with unlaunch install?
and the problem with hiya is with: no such directory in arm7. in pc.

i cant believe that appear the nintendo zone in my dsi.

 

[Tarmfot]

Hello.
I installed HiyaCFW time ago along with Twilight Menu.

One day I got some strange glitches and I deleted _nds folder and hiya folder.
I installed twilight menu l again. But it didn't work.
I realized that I had deleted bootloader.nds from hiya folder when I deleted _nds folder.
I copied it from a backup and then Twilight Menu worked fine.
But I now cannot go to hiya emunand menu.
When I try it using unlaunch menu only Twilight Menu starts.

Some idea to that launcher from HiyaCFW works?

Sorry for my engrish.
