Im going to get my wii modded next week
Wiinija or wiinija delux?
Lots of modders are pushing the wiikey, if you do get one you might want to make sure its real and not a clone, the wiikey looks liek it has the most potential but if youre backing up gamecube games it has a audio streaming issue other that they'll fix in an update.
and heres a few sites you might want to look at:
Compares some wii mod chips- wiikey, wiinija delux, and cyclowiz, eetc.
Heres the wiinija review you might want to look at it (pros, cons)
The wiikey one
And you might want to consiider the cyclowiz (good support, disable function, recent update)
Theres all updatable so thats good
I'd personally go with the wiikey, but its up to your personal opinion and what youre going to use the modchip for (imports, backups, gamecube, homebrewing, etc.)
