Bueno he estado mirando por foros y un tester decía esto concluyendo el hilo:
"No problem. The update includes Gamecube audiofix and dual layer support. NOTHING MORE!!!
There is only limited testing that can be done since, at this time, the update is coded only for DMS/D2A consoles. They are currently working on coding the update for other console versions. There is no ETA on when that work will be completed or when the update will be released to the public.
Testing completed. Topic Closed."
Así que sólo audiofix y doble capa, así que olvidaos todavía de los juegos Wii-JAP que no van, porque seguirán sin ir...
Saludos.
