Worlds first DSi Binary Executable -> ARM Assembly Conversion [DOWNLOAD]

So a while back i posted onto the 3DSbrew reddit forum about how i was able to convert a DSi Binary Executable to a Linux ELF File.
The Link is Here: http://www.reddit.com/r/3DSBrew/comments/16llbo/bin_elf_asm_linux_only/

Anyways, After some research and hard work, i was able to get an assembly source of the DSiWare Application (Ended up having to modify the elf header slightly). the code itself has lots of undocumented, unstable and undefined instructions (Kinda common for game system executables, as they call other chips and OS Intrinsic processes).

Here is the first 100 Lines of LOZ: Four Swords Anniversary Edition

LOZPatched.elf: file format elf32-littlearm

You can download the Assembly Source here: http://www.sendspace.com/file/4yppdd
You'll need to know ARM Assembly to understand this, but feel free to look. the file is huge though (Roughly 214 MB). Enjoy!

 

I don't know if this is a troll attempt (if so then yes, i fell for it) - and if not, I don't want to sound discouraging, but:

This is bullshit. Yay, you used objcopy to take an encrypted binary and add an elf header, and then forced poor little objdump to disassemble those randomly-looking bytes. The binary is still encrypted, the elf header is bogus anyway, and the disassembly is as good as disassembly of /dev/urandom.

 

Wow.

A post so bad it caused a user who hasn't posted in 7 years to log back in.

 

From what I can tell it is bullshit, it's also tmbinc so I'm even more convinced.

 

I knew something looked fishy but this really pointed it out to me.
