Homebrew NUSspli - Install content directly from the Nintendo Update Servers to your Wii U

One question though...
The README.md mentions an installable version via WUP Installer, but there's none on the repo.
Is that right?

An installable version is planned but not there yet. Sorry for the wrong information on the README.

The thing is... I already made one, that's why I'm asking.
But it's cool that an official one is coming down the road at some point.

so after ~4 hours downloading the WiiU froze and had to be force-shut down. When I rebooted I tried downloading the same title to see if the download could resume right where it left off, but unfortunately, the download started completely over, even though I received the warning "WARNING: The download directory already exists" (this made me hopeful that it was going to scan the existing files)

In a future release, it would be great to only need downloading the remaining files that hadn't completed successfully

I have had the app freeze before and I just left it as is and after a while (about 15 mins) the download started again and finished

I waited for 5-10 and thought that was enough that it would have resumed if it were possible... if it freezes again I'll leave it for 20 minutes to make sure it can't come back

pedrobonfim · May 29, 2020

good night, for me it's working well. however for a friend, after he put the game ID and choose any of the options (Nand, USB or download only) the screen goes back to the beginning and does not download. Does anyone know what can it be? homebrew launcher V2.1 fix and NUSspli 1.4

V10lator · May 29, 2020

@dollerbill Rare crashes while downloading are a known bug: https://github.com/V10lator/NUSspli/issues/5

@pedrobonfim Tell your friend to use the debug build in combination with https://github.com/dimok789/loadiine_gx2/blob/master/udp_debug_reader/UdpDebugReader.exe to create a log file:

Debug reader howto:
1) Start the exe file on your PC.
2) Press F.
3) Start NUSspli on your Wii U.
4. Recreate the error.
5. Handle the logfile the exe created over to me.

My download kept failing after a long time, could be network, but unsure why it just drops entirely. Click resume, downloads for a long time again, but ultimately fails every time. I retried this several times for hours last night. I may move my Wii U at some point to test if it is the network or not (I don't have a lan adaptor)

It should continue where it stopped but there's a bug. Sorry about that, will be fixed in the next release (which happens as soon as I'm able to build a channel version).

It's all good man, no need to apologise. We had nothing, we you were good enough to not only make and share this, but to support and continue to develop it.

It continues with the file it was at (sorry if I wasn't clear about this), I think mine was file 17 of 34 or something like that. Each loop through that file failed though, I'm guessing it lost connection at some point before that file finished.

With the smaller files, less less chance of losing connection, therefore more chance of success. The file it stopped at was about 500Mb, with the slow speed, it took a while, but i did give it a good few, long tries.

I will try and make time to move my Wii U to a better location and test more effectively.

dojafoja · May 29, 2020

Does this app resume partial downloads, without downloading the entire file again? I tried reading the source to see if it does but I suck at reading and understanding C. If it doesn't, I wanted to throw it out there that NUS supports Range Requests and you can request a specific range of data in your request header. Thanks for your contribution.

in 1.5 the app freezes before starting to download the games, I tested 3 games and before starting to download it freezes, I went back to 1.4 and it worked normal

Hello.

I can confirm this Issue with v1.5
It (not freezes) stays on the Screen with "Fake ticket created successfully".
Tried install to USB and Download to SD Option and of course different Games.

Waited around 3 - 4 Minutes....
When you press the "HOME" Button it returns after 3-4 Seconds first to the NUSspli Start Menu Screen and then to the Homebrew Launcher.

According to the Log it is downloading.....??

It skips files already completely downloaded but does not continue single failed files. The latter is a planned feature but needs more research as the NUS is a bit tricky here.

@Leogui35 @alexander1970 Thanks for the report, will have a look at it soon.

NUS responds to the Range request just like you would expect from any modern server. In your request header just add:

Code:

Range: bytes=<partialFileSize>-

where partialFileSize is the size of the partially downloaded file on disk, as reported by your OS. I couldn't tell you how to do it in C but in Python it's very trivial and I have tested it thoroughly. The resulting files always install fine. In Python, using urllib2 I do it like this:

Code:

rqst = urllib2.Request(url)
rqst.add_header("Range", "bytes={}-".format(partialFileSize))

Obviously this would look different in C but you get the idea

Sadly it does not. Or... Well, most of the times it does but there are rare exceptions.

Hmm... Must be really rare. I wrote a PC application called Funkii-UI that was once mildly popular. I had a version that I never released that resumes partial downloads just fine using the method I described. I tested it hundreds of times and even had other users test it more times than I could remember. Never had it fail, not even once.

Actually, if I remember correctly, even USB Helper has a hard time resuming partial downloads and sometimes fails. uTikDownloadHelper did it as well, and even freeShop from the 3DS couldn't do it until the devs added Sleep Downloads, which meant that practially freeShop was downloading in the same way the 3DS eShop downloads games.

To be honest it had hiccups when I tested it but NUSspli was in alpha state back then, so it might have been some other (memory corrupting?) issue. Anyway, the largest single file I saw was 1,28 GB and that was with a title around 18 GB in size, so not continuing a single file shoudn't be that bad? Will have a fresh look into it soon anyway but there are more important things on my todo list.
