Just to keep everyone in the loop, There have been some users including my self having issues with the Wiikey mod. Some people are reporting bad compatibility of games etc. I'm happy to say that these issues are NOT game compatibility related
. The issues seem to be related to certain early GC motherboard revisions (these early boards may have a timing issue). Its of course all still being looked into. Below are the results that I personally have gotten with the Wiikey.
The board that is not working properly for me is a NTSC-U DOL-CPU-10 revision motherboard. This is printed on the GC motherboard underneath the heatsink. This is the GC I bought on US launch day. So it may only be very early revision boards not working. This is the same board I have been doing all my testing on. The Wii DVD drive DOES work on this board. A few other users have reported the same issues with this motherboard.
The board that I have Wiikey working on is a NTSC-U DOL-CPU-11. This is the same NTSC-U board that Zenloc was using to test the DVD Drive and the Fusion. Bearteam, a GC-Forever.com forum member is having issues with his DOL-CPU-11 NTSC-J motherboard however.
I also have a cut up NTSC-U DOL-CPU-20 motherboard. when I get some time I will also wire this board up to test. Gonna be a bit though.
Some video's of the different motherboards behavior.
As you can see the DOL-11 board works flawlessly. I can press the "eject button" whenever I want and the GC does not hang. It also loads all the games i've tossed at it so far without error.
The DOL-10 board however hangs when the "eject button" is pressed UNLESS it is pressed exactly at the right moment at GC boot. Even when done with the right timing though, the wiikey menu will load but all but a few games hang at the cube logo when the GC is rebooted by the fusion. You can see in the video that the blue LED on the fusion stays lit the whole time after reboot. The only games I got to load properly with this motherboard were Resident Evil 2 NTSC-U and Zelda Collectors Edition NTSC-U. Both of these games load flawlessly every time...
