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.

Would screenshots even be possible? Not really asking for it (although i'd love it), but can it theoretically be done?

Try redownloading latest nightly from the DSiMenuPlusPlus-update repo.
Also, off-topic. Please post bootstrap-related stuff here.

You can download it here, although that's useless, unless you hack you hack your DSi for it. You can follow the hacking guide here.

Ok I've been trying to install this HiyaCFW alongside with dsimenu++ on my japanese DSi LL. The first problem I encountered was after installing Unlaunch, it should be boot to the 'silent' version of dsimenu but mine not, it's only stuck on black screen with some japanese characters on the below screen. I try to find the solution and someone who encounter the same problem said just carry on to process until the end. And it's works. My DSi now has HiyaCFW with dsimenu++ on my SD Card. The biggest problem now is I don't know how to access roms on my flashcart. The only reason I install HiyaCFW and dsimenu++ is to make the UI of my DSi in english, I don't intend to play any dsiware and homebrew. So, is someone here know how to access my flashcart again? I don't like to access my roms from SD card because the compatability issue. Oh, and FYI, my original firmware is 1.4.2 and the flashcart I use is R4i 3DS Lite, I believe it's a DSTT clone. Thanks in advance for your help and sorry for bad english

You can just launch the flashcard from DSiMenu++.
What games in particular do you want to play? There's a chance that some of them may be compatible from the SD card.

Hhmm it's strange, I don't see the option to access the flashcart. For now I want to play Solatorobo which I believe has some issues if accessed from sd card

Press start, then select "Launch Slot-1".

Solatorobo works fine from the SD card. The ROM needs to be AP-patched on the SD card for it to work properly.
If you're still having issues, even after AP-patching the ROM, try turning off async prefetch.

Well... Good to hear that but again, it's only solve my problem for now, because some game I plan to play like Dark Dawn and Bowser's inside story still red in the compatability list. I wanna mention though, like I said before, after installing Unlaunch, it's suppose to boot the 'silent' version of dsimenu but mine not, what's the problem?

You have to set it to autoboot DSiMenu++ in the settings.

Thank you very much your help... Well I will try again to install this cfw because last night I revert back to the original

Would it be possible to use HiyaCFW through the hb launcher?

 

[RocketRobz]

No. You need Unlaunch installed.

Hi.
I start my DSi with HiyaCFW, and it gives me this error:

Error!
Launcher's .tmd is too big.

Please replace it with a clean one.

I don't remember modifying any .TMD archive. Any sugestions?

Your .tmd dumped from the NAND contains Unlaunch.

 

[E1ite007]

Your .tmd dumped from the NAND contains Unlaunch.

Any way to get any other without Unlaunch?
