Tu as dû faire un copier coller du code de là bas.

:D

There are a few minor differences with Python 2.7 when creating the code objects but the same principles apply.

merci pour cet article très intéressant !
J’ai une petite question de curiosité, pas vraiment au niveau du hack en lui même mais plus de la prog’ Wii.
Tu as dit avoir fait un programme pour allumer la LED de la Wii.
Pour cela, tu as fait du C/C++ “natif”, ou bien utilisé une lib comme LibOGC (de DevKitProPPC) ?

Car pour tout dire, je suis pas (encore) trop à l’aise avec les notions électronique, enfin je ne sais pas vraiment où trouver les docs pour avoir l’adresse mémoire pour contrôler la LED par exemple..

Donc si tu as fait du “natif”, ça m’intéresserait grandement si tu pouvais m’expliquer ^^

En tout cas, merci encore pour l’article :)

And I thought I know a lot about Python and sandboxing :) keep up the good work.

I am definitely kicking myself for over thinking this one (and burning many hours in the process)
I wrote a kernel module to emulate /dev/dsp, with a simulated the IOCTL interface. Used matlab to work backwards from __<P_Y5GYP<jGPY5GYP5CPG_ in order to simulate the correct values to the read(..) and get the program to exit the "expected vals" processing loop. Hehe. It's easy to caught in the weeds when working these problems solo. Thanks again for the solution.
