I was lucky enough to get my wii at TRU with LU564 which still came with code printed under the GC2-D2C, my other friend was not that lucky, he got his at walmart with LU567 which is just GC2-D2C on the chip set.
I guess if the new chip is implemented, it is started somewhere in that range.
No print underneath doesn't mean it won't work - just it may not.
Plenty of drives with no second line can be modded fine. If you want to play it safe with your friend's get a d2ckey and wii clip.
My vote is still for a firmware change in the dvd-rom itself. Maybe this was done to improve dual layer reading or something, and they just happened to change some other stuff around that messes with the chips.
New d2c chip in the wild, dumped by d2ckey team - 2008-05-05
We received the first drive with the new d2c chip on yesterday and we can confirm that is indeed different. We have dumped the firmware and are just starting to analyze it. It seems that nr reader mode has been disabled in this firmware (see nice screenshot of firmware disassembly).
i wonder what this means :-) can someone explain this in easier words?
what exactly is the "nr reader mode"?
or other question:
can the d2c firmware be updated by nintendo on existing wii's?
can this be worked around by chips or do we have a huge problem with this?

Nice one D2CKey team (dunno why this news wasn't realised under their D2Pro website?).. this will atleast stop all the speculation. I'm to first to admit that I have no idea what the above code change actually means.. can someone who knows please shed some light...
Looks like the guys are right on top of this and look forward to any progress.. cheers again, Chris

I'm not sure what this NR Reader mode is all about but on a search of google Gamecube had a NR Reader model which companies would use to test their games (like developers would put a copy of their game into the machine, they were nintendo endorsed and cost a lot of money)
Dunno if it's related to that or not.
Let's hope a fix arises soon, it was probably put on the D2CKey website first because of the chips ability to work on all D2C's and probably because they were the first team to make a D2C chip so they probably want their users to hope they will be the first to release a chip/fix for this one.
I believe NR = Nitendo Revolution, which is the project / code name of Wii development. In short, Nitendo changed the way it reads the DVD, slightly. I certainly hope a firmware update of d2pro will solve the problem.

Are the developers at D2CKey not the same as the D2Pro team... ??

Not that i can remember first year uni Assembly class too clearly, but:
the blue line is just the name of section of code,
the green writing is jsut a comment on the code, so its irrelevant.
sub D0, D0 --- I'm pretty sure this means its substituting D0 for D0 (an address is memory perhaps? i dunno), which means its doing nothing.
RTS = Return to Subroutine, which means its the end of the code block.
So the whole section of code does nothing when its called....which is why they are saying "It seems that nr reader mode has been disabled in this firmware"
