Letterbomb

Are you sure you only used 0-9 A-F?

There are no Os

--

Is your browser interfering?

 

The thing is, I doubt it knows what is a valid mac address or not. So it's not the fact that it's wrong, it's either in the wrong format or not enough characters or something (try a different browser)

 

Letterbomb will only work on 4.3 system menu's...........

 

... And the website have no idea what your SM version is. So thats completely irrelevant in this case.

 

Quoted from some other site:
"Some Wii's have MAC addresses that don't match with Nintendo's list of MAC addresses (for example 00:1A:E4:xx:xx:xx or 0e:0c:7f:xx:xx:xx will not work). There is no way around this so if your Wii's start with these MAC address prefixes then you must use a different exploit."

There are only 281 trillion or so MAC addresses out there, they were going to have to buy/borrow/steal some of them eventually.............

Letterbomb must use the IEEE list to check for validity.....

 

you can still hack it, you just need to use an exploit disc, if on 4.3.......and hack with modmii, dude...
