Aunque se ha retrasado bastante, al fin aparece una actualización para este modchip de Wii.
Ahora sólo falta a que actualicen la web oficial(wiikey.cn), aunque ya está para descargar en otras webs.

Full GC Regionfree                                              
 Boots GC imports directly using a small apploader hook to setup  
 the correct video mode. To enable this feature use the new       
 config disc (1.3). Make sure you also enable the basic region    
 feature, thats what gets you through the wii menu in the first   
 place. Unlike a real GC, the NTSC Wii doesnt output PAL50. That  
 means the game may run but theres no picture. PAL60 games will   
 work, however you need to enable it. The common way to bring up  
 the "use PAL60?" dialog on a game is to hold B while booting.    
 Forcing to NTSC may work as well. PAL consoles output NTSC just  
 fine.
