[RELEASE] dumpling

SUPER MEGA AWESOME! Thanks for this great tool!

 

Awesome!

 

Alright here i am with testing lol:

I get this weird thing saying i have to run MOCHA, why wouldn't it work with HAXCH? Cause that is what i ran and i got this screen:



Plus is not working with PRO Controller, nor Wii Mote.

 

Hello.

Yes,you are right:

So I do not think we have luck with this great Tool.

 

It's the first release, there is still time to add the other controllers support and fix the issues... like this:

**ISSUE**

After fetching the meta for all my USB GAMES in order to dump them individually... the thing just froze completely and is NOT responsive. I will have to turn off my Wii U


EDIT:

I'm fetching all the titles again, if it freezes then the app is definitively not working because this fetching thing needs to be done EVERYTIME you open the app... therefore is broken because if it freezes while fetching... there pretty much NOTHING you can do with it.

EDIT:



It's been stuck there for 10 minutes now, this homebrew needs some more work :v

 

He says why in the Installation section of this thread:
Dumpling uses iosuhax and requires MochaCFW to run, and won't work without it.

It uses iosuhax, which Haxchi doesn't support

 

Yeah and regardless, if you're on CBHC you can just add Mocha to your homebrew launcher, launch it, go back into the homebrew channel and then launch this app. If you have CBHC, mocha is completely usable and super easy to access, just like any other homebrew app.

 

All the issues i reported were with MOCHA CFW, nothing else. Except the one that reports the "iosu" problem...

 

"Dumpling uses iosuhax and requires MochaCFW to run, and won't work without it"
The OP already explained it wont work if only using Haxchi (for the time being).
I tested dumpling to save/dump my haxchi installed game on NAND and a NES game installed on my USB, both we're dumped succesfully (in loadiine format btw). Check your SD card or USB first.

 

I was just answering your question about why it wouldn't work with Haxchi. Its too bad that it has some issues still. I saw that he was asking for testers on Discord before releasing this. He must have thought it was ready to go. I personally haven't tried it yet.

 

Im more than happy to test, but as for now it doesn't work for me. After fetching all my 192 games the app crashes or freezes and does nothing. xD

 

this is great, now i'm gonna do some "legal" backups of games that i "totally bought"

does this only dump games in loadiine format or this can also dump games in the WUP format?

 

I have the same question for the dev of dumpling @Lia

 

Haxchi supports iosuhax.
Haxchi has an integrated wupserver that you can start using an ioctl command.
I created a pull request for haxchi support.

 

... but if you're using haxchi/cbhc you can still launch this, just get the mocha homebrew app and boot that from the homerbew launcher after you've booted your Wii U with haxchi/cbhc, that will boot you back to the Wii U menu, and then go back into homebrew launcher and launch this app. I have CBHC and this method works without issue. Sure it takes an extra 30 seconds than if it could natively support Haxchi, but there is still a totally viable method of loading this if you have haxchi installed allt he same.

 

To be fair, I don't understand C and I can only read/write Python, which barely counts! I was basing my comment off info received from a credible dev, Maschell. In this thread here: https://gbatemp.net/threads/what-is-iosuhax.481166/ he says this about libiosuhax and Haxchi:

When asked about Haxchi having support for wupserver he said this:

This was all said in August 2017 and there hasn't been a meaningful commit to the Haxchi repo since January 2017. Either I'm misunderstanding or Maschell misspoke about it.

 

I actually don't know what Maschell means but Haxchi comes with it's own wupserver that supports all IOSUHAX commands since december 2016 that can be accessed via the MCP.
Mocha has an extra node (/dev/iosuhax) that always runs in the background and recieves commands while haxchi patches the mcp code 0x62 to start wupserver. I don't know what Maschell means with hardcoded support... With haxchi you just need to start wupserver manually and you can then open iosuhax via the mcp node and send commands to the ipc.
You can start it like this:

Code:

IOS_IoctlAsync(mcp_hook_fd, 0x62, (void*)0, 0, (void*)0, 0, someFunc, (void*)0);
//let wupserver start up
sleep(1);
if(IOSUHAX_Open("/dev/mcp") < 0)

Good job man.
