Bypassing Error Code 20102 on all games

Nintendo banned some MKWii cheaters on 2nd July 09. It's the 2nd ban wave. First one was easy to bypass by changing Wiid. Last one is a little bit more permanent: they ban Wii's wifi MAC address. But I found an easy way to bypass MAC ban: changing last MAC byte before is sent. Also, this code could be useful to avoid permanent ban because they will ban a FAKE MAC address.
This code works on ALL regions, ALL games (even WiiWare). Just one requirement: GECKO OS 1.8 or later. It will not work on USB loaders or Ocarina.

[Universal EC20102 bypass - mdmwii - REGION FREE]
F6000001 8001807F
7F83E378 38A00006
D2000004 00000003
3A6000ZZ 9A640005
3A600000 38A00006
60000000 00000000
E0000000 80008000

ZZ = Desired LAST MAC byte(It must be different to real MAC)

If you haven't noticed. Me and mdmwii are now both hacking and posting what we can here. Enjoy.

... and mdmwii.

If the video's already on youtube you can still embed it.

You only need to put The Conduit videos on through blogger because HVS will delete them on youtube.

Hey Hetoan, do you think you could release a text file along with the GPF file? I would really like to switch on and off the codes. If not it's understandable. But if it is possible I'd appreciate it! Thanks


July 10, 2009 at 4:11 PM

yeah a txt file would be cool. you should make one up if it isn't trouble. i don't see how it could be too much trouble to do that though


July 10, 2009 at 4:51 PM

dude gpf would be fine... he doesnt wanna release the actual codes is all. he might release some of them in the .gpf tho so that it would be built into your game save.


July 10, 2009 at 5:01 PM

Yeah but is there a way to take out some codes, incase there are some that come with it you don't want. Cause all I really want is the crouching one, the debug so I can select my weapons, hidden on radar, and show players. I don't want to have infinite health or ammo of any sort. Or moon jump.


July 10, 2009 at 6:09 PM

well, u'll get what u get i guess, its hetoans choice. for all i care he can just keep them to himself. just be patient


July 10, 2009 at 6:47 PM

I am patient, I was just asking if he could release the text file. I wasn't telling him to do so. Just a request.

Hey quick question: How do you find your default MAC address?


July 12, 2009 at 2:44 AM

in the wii options menu, under internet options


July 12, 2009 at 4:31 AM

Cool thanks!


July 12, 2009 at 3:54 PM

How do we actually know this works?


July 13, 2009 at 10:34 PM

I've tried testing this code on bleach versus crusade RBXJ8P and it gave error 20109 which is

Error Code: 20109

There appears to be a temporary issue with the Nintendo Wi-Fi Connection. Our technicians are currently working to resolve this problem. Please try your connection again later.

When I turned off the code the game worked as normal.

I was using gecko os 1.9.1 and I tried different values for the "ZZ".


July 14, 2009 at 9:06 PM

so u post this code in the game u wanna bypass rite.


July 16, 2009 at 10:37 PM

I don't suppose it's possible to make the code compatible with usb loaders and ocarina? I would love to use gecko os but my disk drive is dead. I haven't been banned yet, but I figure there's a high chance I will be just for loading via usb loader, and would like to be able to continue playing online.

So you can free willingly turn this code on and off? Wow so uhh...What would happed if you disable this code WHILE on wifi? Will you sudden'y be disconnecteD? o.O

Very clever hack.
I love the concept. But does this mean that I can only play online games with homebrew now? Or can I use the code once, and play through disc channel?
