Homebrew Unlaunch v1.9 released

werdy · Apr 30, 2019

NoCash has released an important update for his DSi exploit, Unlaunch. Among others it fixes an installation problems on systems, which were updated with wrong (old) date settings.

Unlaunch.dsi is the first ever [released] bootcode exploit for DSi consoles.
It's gaining control with full SCFG_EXT access rights immediately after power-up (before even starting the launcher).
Installation requires a working DSiware exploit with SD/MMC access, or a hardmod.
The exploit works with all retail DSi models, regardless of region and firmware version.
Once when installed, it will start the file 'bootcode.dsi' from SD card (if present).
Or, otherwise, it will resume booting nintendo's launcher (with disturbing healthsafety and bootmusic disabled, and removed RSA, whitelist and region checks).

v2.0 - 27 Aug 2019
- extra ipc sync before arm9 vram remapping (avoid memory pit arm7 vram crash)
- cosmetic: Wifi-LED kept switched OFF during/after wifi-firmware init
- bugfixes: initializes dsi_flag AFTER vramcnt, and fixed options glitch
- removed warning on unknown chinese region (no longer unknown)
- wifiboot: faster reconnect on warmboot, rtc set, icon/title

v1.9 - 28 Apr 2019
- wifiboot: supports DSi-wifi SDIO hardware with WPA/WPA2 and faster transfers
- updated unlaunch.htm webpage and how-it-works screen (hotkeys, bootcode.dsi)
- no$gba: fixed wifiboot uploader (without nocashio for wifi) (no$gba v2.9c)
- detects MMC cards in SD/MMC slot (upon failed APP_CMD during idle state)
- initializes 2FFFCFAh wifi channels (for dsdownloadplay and pictochat)
- added lowercase font, hotkeys: removed experimental dpad up/down hotkeys
- displays title from icon/title (if any, instead 12-letter cart header title)
- removed unknown firmware warning (wasn't working, and v1.0J is now known)
- filesys/speedup: uses 1-sector fat cache for faster next cluster look-up
- filemenu: also shows files with .srl extension (in case anybody uses that)
- hotkey config: new options include keep (no change) and none (ignore hotkey)
- forces pub/prv savedata size zero for NDS titles loaded from SD/MMC

v1.9 deletes the System Settings from your real NAND on v1.4.5E, dunno if it happens on other systems as well...

Valery0p · May 3, 2019

Could some report it on nesdev please? Nocash has issues with https pages.

Reported, don't know if I did it correctly though...

Checked on my system (1.4.5j) and it is not missing.

Maybe it's a EU console-only issue?

That would not be the first homebrew.
Can you boot TWiLight/Settings ?
Can you boot into your SD Nand ?
Can you downgrade to 1.8 ?

Thank you.

Thank you.

I can downgrade and everything, I can still do everything, the app is just completely gone from my NAND.
I got everything under control, no help is needed.

Just to update the thread: it turned out, that this issue (missing app) wasn't a bug of Unlaunch.

It was trash_bandatctoot messing up with his system, as he explained here http://forums.nesdev.com/viewtopic.php?p=239259#p239259

It is a pity that we were not allowed to experience this here.
I am sure it would helped many users here. :cry:

Thank you for the reconnaissance in the 1.9 case.

KoopaMaster · Jul 8, 2019

For sure. I'm using it on two 1.4.5.J DSi since the release without any problem.

If we talk about SD-card detecting...its not possible for me to use, I just want to install Hiyah CFW, but it doesn't show up. Has somebody the same problem?

Hello.

There are a few Things to pay Attention please:

- What Type of SD Card do you use ?
(microSD with Adapter and some SDXC Cards are not 100 Percent reliable)
- is your SD Card formatted with FAT32 ?
- did you use the HiyaCFW Helper and your NAND Backup (that you hopefully made at first after the Camera/Memory Pit or Flipnote Exploit on the HB Menu)
to install HiyaCFW and TWiLight Menu on your SD Card ?

Please look at these Points and be so kind to tell us your Progress.

Thank you.

Billy1006 · Nov 25, 2019

I've been using a MicroSD card with 2gb of space, and a Samsung Micro SDcard Adapter since I have no regular sd card. Beside this point i followed the points correctly and yes, my sd card is already formatted, I did it yesterday and tried a few times, but it doesn't work at all

--------------------- MERGED ---------------------------

Also, I tried the latest releases or the helper but it also didn't make a change

Hello.

Thank you.

As the Hint is already given:

- What Type of SD Card do you use ?
(microSD with Adapter and some SDXC Cards are not 100 Percent reliable)

Please try to get an regular SD Card.
Thank you.
