wiifuse_server is a Wii application that responds to wiifuse requests coming over a usbgecko adapter from a remote host. This allows you to mount the Wii internal NAND filesystem with full read/write access remotely on your computer.

WARNING: watch exactly what you are doing, you can BRICK your wii with this tool. use at your own risk.

Prerequisites

An OS capable of running wiifuse
wiifuse package (v0.2.0 or higher), the server described here is part of it
USBgecko adapter
Comprehension of the Wii internals

Build

A precompiled binary is included.

To compile the included code, you will need:

devkitPPC and libogc
- r14 or higher

The server code resides in "./server". Run make there.

How-To

You will need an identity to authenticate against the Wii's ES subsystem. An identity describes the access rights you have on the NAND filesystem. It consists of 3 files:

These 3 files are, e.g. part of a Wii image. You can use wiifuse and the included shell script to copy these from a data partition to the needed location:

~/devel/wiifuse/ ./wiifuse ~/zelda-tp.iso ~/fuse
~/devel/wiifuse/ ./server/get_identity.sh ~/fuse/data zelda
found 'The_Legend_of_Zelda_Twilight_Princess' (00010000525a4450)
`/home/dhewg/fuse/data/.internals/certs' -> `/usr/local/etc/wiifuse/00010000525a4450.certs'
`/home/dhewg/fuse/data/.internals/tmd' -> `/usr/local/etc/wiifuse/00010000525a4450.tmd'
`/home/dhewg/fuse/data/.internals/ticket' -> `/usr/local/etc/wiifuse/00010000525a4450.tik'
create symbolic link `zelda.certs' to `00010000525a4450.certs'
create symbolic link `zelda.tmd' to `00010000525a4450.tmd'
create symbolic link `zelda.tik' to `00010000525a4450.tik'
done
~/devel/wiifuse/ fusermount -u ~/fuse

To mount the NAND filesystem with the zelda access rights on PC side:

~/devel/wiifuse/ make -C server upload
make: Entering directory `/home/dhewg/devel/wiifuse/server'

notes

don't use this if you don't understand it to 100%
it depends on the identity which paths/files you can access and which not

All the reversers out there. this tool just demonstrates a few new functions of libogc
The usual suspects, without you this wouldn't be possible

This modified version of wiifuse uses the network instead of usb gecko: http://emergent.unpy.net/01212803011
