Hacking Sad, unfinished port of an ELF loader.

[MrRean]

so like, there's a elf loader for 5.3.2 on the libwiiu repo that works fine, so i attempted to port it to 5.5.1 and it's a pain in my rear so

https://github.com/MrRean/551-Elf-Loader

do whatever you want with it. it's very broken, it doesn't even work yet. i tried to keep 5.3.2 from breaking so im not even sure that works.

but here you guys go, it's not working at all but im putting it out there for other 5.5.1 people to finish it if they want, and they at least have a base to work on.

derp

credits are on the github repo

It loads ELFs.

 

[_v3]

It loads ELFs.

Does it work with DWARFs??

Anyways, thanks MrRean, even though you gave up you did atleast something.
Seems like 5.5 and 5.5.1 homebrew is still far away.

Ah yes, I forgot; where are my manners?

Thanks for this MrRean! I'm sure this can be improved upon and maybe even turned into something really good!

My ported elf loader for 5.5.1 doesn't work either. I did some trial and error and found the problem at curl (It doesn't want to download the .elf file). Sadly I don't know how to fix it. However nice to see someone who also whats to port it

This is what you are looking for, probably, at least some of it. (You have to reinitialise the internet connection.) Also have a look at the new Loadiine gx2 installer to see how elf loading is handled.

I have elfloader loaded on 551 but stupid elf examples can't build cause of error makefile *makefile build cannot be create*. I get build folder with nothing in it (aka boot.elf). Am I missing something.

Take mine, I have builded the example correctly. Would be awesome if it works. http://josamilu.de/wiiu/boot.elf

What's this thread about, and what is an ".elf" file?

I committed a possible fix. Redownload the github branch and try again.

I am not at home rigth now, and won't be able to test it until friday. Would be nice if someone other can do it.

A Format for executeable files. Look here for further information : https://en.m.wikipedia.org/w/index.php?title=Executable_and_Linkable_Format&redirect=no

Excellent! I have a friend with an engineering degree I want to show this to right now

 

[brienj]

I will gladly look at this when I finish the program I am working on. I want this too.

Such a shame everyone is spunking allover smeas work that wont be released when we have the potential of getting a working ELF loader that has code released. I have a friend looking at it but he has never touched a wiiu in his life, however he is very gifted, I hope he can help better than I can. He is checking out wiubrew and stuff to help him before he starts, something every member on here can do.

Yeah, I am working on some programs, hoping it will show there is interest in homebrew on the Wii U. From everything I've seen, smea won't ever release what he has, I am just trying to hopefully show Hykem though, that there is indeed some individuals hungry to do some coding on the Wii U. In the meantime, I've been tinkering around, looking for entry-points on my own, and if I find anything, I won't hesitate two seconds to release it. If Nintendo patches it, they patch it, it's easy to keep from getting updated.

Im learning basic java and c, Im not very good, however I do lots and lots of hardware mods and Im lucky my best friend is 3rd year masters in engineering so have someone to learn off, with hardware Ive done nand mods on ps3 using teensy, fully rebuilt a nintendo M82 demo system and outfitted with a custom ASIC etc. I hope as I improve with java and c that I can start contributing to this scene and whatever scene comes next. Hykem as good as he is and as nice a guy he is made the mistake of saying he was sure of release before febuary which ruffled a few desperate feathers, Im sure he knows there are a few learning, reading his excellent documentation (and yellow8's new stuff is mega interesting btw) between all the shitposts and whiners.

Mrrean is awesome for providing this. Thanks dude.

I've been programming for over 30 years. ASM, C, C++, C#, Java, and Python are just a sampling of what I've used. I also cracked a lot of the original Xbox and Xbox 360 stuff. The Wii U is PPC like the 360, so that kind of got me interested in looking at it, and also the fact my kids wanted one. LOL

My kids have been messing around with the program I'm writing right now. I keep adding a little more and a little more, but it is still within the limit, so I'll keep adding what I can. I developed a little library for drawing simple shapes with limited memory use, and hope to have a whole alphabet eventually made with it. I was not happy with printing strings in rows and columns, now I can print exactly where needed.

Edit: Well, I just found out what I was trying to add put me over the memory limit, so I scrapped that idea for now. I'll just keep adding the few things I need to add, then have it finished. BTW, I thought the limit was 32k, my bin file was at 24k when it failed. I removed the extra library and it is back down to 19k and works again.

I get this when loading elfloader https://www.dropbox.com/s/oowsm2km80j9tig/20160208_220045.jpg?dl=0. I get leader fails and freezes my wii u.

 

[MrRean]

if(leaddr == (char*)0)
     OSFatal("leaddr fails");

means it's empty.

Name your PHP file in the folder "payload.php" and put the elf in that directory. (what you get from compiling elfexamples)
