Dimok at gbatemp released a few different things.
First something he aimed for those interesting in developing.
Now I wrote up some IOCTL commands to allow easy FSA access and to allow SVC syscalls, memcpy in and out, IOS kernel read and other usefull stuff from the PPC side. This is still in development and can be extended with more usefull commands. You can see all the changes on my iosuhax fork here:
Also a FS2Sd which allows you to dump your wiiu contents to your SD with more control over what,
I created a new application called FT2SD (File Tree 2 SD). This application is a file tree dumper to SD. It can dump several (currently) predefined paths directly to your SD card, like for example game disc content, updates, tickets, slc content, vWii content, mlc…Think of this tool as a very pimped ddd alternative. It might even miss some interessting paths but those can be added quite easy.
The application is currently only a console application but I think i will improve it later with a GX2 GUI and make a nice explorer tool out of it where the user can change paths and copy stuff back and forth.
And lastly a FTP2Wiiu that he warns could cause bricks if used improperly.
Now this tool is only for advanced users ONLY. This is an extension to the existing ftpiiu tool. It mounts all the paths listed in the FT2SD tool and offers them on the FTP. This includes SLC and MLC! You can also add files or remove files on the FTP which makes it quite dangerous if you do this on sysNAND. So therefore here is a fair warning:
DO NOT TOUCH THIS TOOL IF YOU DON’T KNOW WHAT YOU DO. IF YOU MODIFY FILES ON sysNAND YOU MIGHT BE SCREWED!!!
