Hacking Wii U Hacking & Homebrew Discussion

[Mr. Mysterio]

So we could in theory convert DOL to ELF to RPX and kickstart Wii U homebrew now through Loadiine?

Or, just build an ELF loader with the browser exploit.

I'm pretty sure you need IOSU hack to spoof the firmware, but I didn't explore much the spoof topic =). But maybe ..


Nop I can't load the game complety, it always crashes at some point.
In the video it doesn't crash because I skipped the loading of one file with cafiine, so it can't loads till the end (when the file is retrieved by network, just after retrieving the data, the wiiu can't communicate anymore, I don't know why, maybe network problem, maybe thread problem, maybe i didn't implement well some filesystem function ...).
It also happens with other games I tried. Still investigating ...


For the moment it's still in development state with most of the stuff done by hand. I'll try to make easy tools when everything will be released.
note : cafiine doesn't do the dump, it is only used to send the game files and mirroring the filesystem functions.

So its another program your doing that can dump the executables?

It's almost the same program as loadiine, instead of replacing the rpx, it copies the application rpx somewhere in memory , so that you can retrieve the data afterward when the application is started.

I need to clean my code, and make it usable and understandable for devs who wants to work on it.

Maybe you could change the send buffer to a smaller one. The buffer in the base cafiine version loads the whole file at once. I had some problems with large files (and extreme ram usage ^^) so I changed that and it works great.
My version is here: Program.cs https://bitbucket.org/n1ghty/cafiine_n1ghty

Oh, and my version creates all used files in a _structure folder... That was easier for me than to go through the log files when I was looking for modable files

hopefully that will get released as well since dumping VC roms that dont have rom folders would be interesting so we could see if snes and nes do have writen in the executable config files.

I tried sending byte by byte and stills crashing =).

No, it doesn't work like that, for one you'd need to rewrite the whole graphics backend since Wii/GC just shoved everything into the DOL, now we have dynamic linking with libraries and a brand new GPU.

Ok, thanks. I was thinking it would be cool to start getting emulators ported asap, but I guess work will actually have to be put into it lol

considering we dont even have usb acess yet those emulators would be preety worthless even if you fixed all the graphical part lol.

So...no emulators are ever gonna happen? Guess we're stuck with the largely unsuccessful VC injections then We all know how well that went last week. Damn hard-coded emulators.

Considering how small the roms are it would probably be feasible to load it all into RAM in one go, that way you don't have to deal with the network bottleneck

IOSU much?

 

[EpicLPer]

So guys, any news about the firmware spoofing already? I'd really want to give Mario Maker a try already but I'm still on 5.3.2 and I have to download it from the eShop, but won't matter anyways because that game sure brings an updater with it...

 

[JaceCearK1]

Would it work in reverse for native compatibility with ELF files? Or is the transfer only possible one way?

That was also one of my thoughts!
We don't have to bother creating an ELF launcher if we could just convert them to RPX and launch those!
On the other hand one could just tell the compiler to output code as RPX, but having options is always good, isn't it?

at least it works eh.

I'll be glad to get more stuff working We just need more people here

 

[Mr. Mysterio]

It may also be feasible to load, say, a GCN ROM over the network and save it to the eMMC. Then an emullator could load it from there.

 

[LawnMeower]

Would TCPGecko (Cafiine and other tools) be able to connect to a Wii U only through the USB to LAN adapter?
Or is USB access too restricted for that?

No, it means they need ported to Wii U, not that they will never happen. Converting an ELF to RPX would essentially be the same as trying to open a JPG as an AVI file, it's not the same as porting a piece of software. That's done in C/C++ etc from a source like Cafiine or the OsDriver hack. That's not to say it's not possible to switch between formats that something supports though, such as ELF and DOL. ELF is essentially a container, not platform specific (although the ELF itself may be). If just converting any old ELF's to RPX would work, I'd be converting a whole library of PS2 games!

As far as the Wii and GC homebrew go, it's not surprising they will need ported. They will come eventually, just stop being so negative.

anyway, after digging, vc injection is not as bad as it seemed to be.

is there one for anything above 3.1.0?

i get the impression you haven't came across the randomizer before
