GQoobPro on FreeBSD

Sometimes ago I dug up my old GameCube to give a try to GBI, a very impressive homebrew alternative to the Game Boy Player Start-up Disc.

To load homebrews, the GC had been modded 10 years ago by someone with a now impossible to find Qoob Chip Pro. This great modchip was only provided with a Windows software to flash it. However while looking for a copy of the program, I stumbled upon a really nice Linux CLI version by Joni Valtanen. The software compiles and run fine on Debian, but I also wanted to have it available on FreeBSD. As it turns out, making it working for FreeBSD was fairly straightforward. Crappy patches below.

The flashing software comes in two parts: libqoob and qoob-flasher. Only libqoob sources need to be very slightly adjusted. FreeBSD comes with a specific libusb implementation, so there is no need to check for the regular one while configuring, but the libqoob pkg-config file needs to be edited to point to the libusb shipped with the OS. Also, pkg-config files are not located in a subdir of the lib directory on FreeBSD. All together, some changes need to be made to Makefile.am, configure.ac and libqoob.pc.in:

Almost there. FreeBSD needs free() from its own memory allocation functions:

Now libqoob will compile and install fine, and qoob-flasher will configure, compile and install nicely out of the box on both Linux and FreeBSD.

It’s now time to plug your qoob’ed GC which will be claimed by the generic USB HID module:

ugen1.2: <QooB Team> at usbus1
uhid0: <QooB Team QOOB Chip Pro, class 0/0, rev 1.10/1.00, addr 2> on usbus1

However unlike on Linux, qoob-flasher will not be bothered by that, so there is a no need to blacklist the device! And now let’s flash some homebrew :)
