Wii U GamePad on Linux
Early work on talking to the Wii U GamePad from Linux: an out-of-tree mac80211 module with DKMS packaging, firmware-dump tooling, and documentation for libdrc.
In 2014 the Wii U GamePad’s wireless link was being reverse-engineered by the libdrc project. The GamePad speaks a modified Wi-Fi, so using it from a PC needed a patched mac80211. The studio’s founder took that patch out of the kernel tree: backported to 3.11, then 3.13, built as a standalone module so nobody had to recompile a kernel, and packaged with a DKMS configuration so it survived kernel updates. The module lives in the drc-mac80211 repository on Bitbucket.
Alongside it came a Python tool that parses GamePad firmware flash dumps and splits them into their parts for analysis in IDA, contributed to drc-re-scripts, and the boot and image-resource documentation of libdrc itself (seven commits, preserved in the GitHub import of the library).
