Wii DVD/Wiikey Fusion/WODE (sd/hdd loading) on Gamecube Guide/Tutorial Direct copy from the gc-forever.com forums.
Things to know ahead of time:
1. You will need some soldering skill to perform this mod.
2. If you want to retain the ability to hook the original GameCube DVD drive back up you may solder to the DVD connector pins on the bottom of the GC motherboard (only one can be hooked up at a time!). If you plan to remove the connector a desoldering iron is recommended.
3. As of right now only original GameCube discs work with the Wii DVD drive mod. This may change in the future as different GC and Wii modchips are tested.
4. Not all Wii DVD drive revisions are tested.
5. When the Wii DVD drive is connected to the GC the disc insertion/disc eject (slot loading mechanism) acts kind of funny.
6. The Wiikey Fusion is not compatible with all Gamecubes! See the compatibility list below.
7. Last but not least, We are not responsible for anything you destroy or electronics that go up in a puff of blue smoke whilst attempting this Mod. If you read and follow this guide carefully you should be ok.
For those interested here is an early video of the testing of the Wii DVD mod: http://www.youtube.com/user/Ashen123451 ... MeXMlDtaGE

That all being said, on to the meat and potatoes.
Wii DVD/Wiikey Fusion/WODE Jukebox to Gamecube Mod:
These are the connector pin out's of the Wii DVD Drive and Modchips confirmed working with the GameCube:
Wii DVD Drive:
Wiikey Fusion:
WODE Jukebox:
In reference to the above pinouts, all of the connectors pins 1 through 32 run from right to left. Pin 1 being rightmost on the connector and ending with pin 32 being leftmost.
Special Pins/Connections:
Pins 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20 are ground pins and must be connected with a common ground on the GameCube motherboard itself!
Pin 32 Needs 3.3v power input to power the modchips. The Wii DVD drive will function without this hooked up.
Pin 23 Is the "lid open/closed" signal. Wire a on/off switch between this connection to retain the ability to "open/close the lid". The normal GameCube lidswitch is fine. This is needed for multi-disc game disc swapping.
Pin 29 Simulates the Wii's eject button and also controls disc sensing. This pin needs to be run to a normally closed momentary tact switch which is then run to the GameCube's ground. The DVD drive/Modchip WILL NOT FUNCTION unless this is done exactly as stated. Here is an example of the type of switch you will need:
The common (C) pin should be run to pin 29, the normally closed (NC) pin should be run to the GameCube motherboard's ground and the normally open (NO) pin should go to 1.9v from the GameCube's regulator (1.9v is only needed for the Wii DVD Drive! Wiikey Fusion/WODE requires only the pin29/switch/gnd).
Little update from none other than our ol' pal Shockslayer that I think is worth noting if your having issues getting your wiikey to work:
Pins 30 and 31 are left disconnected.ShockSlayer wrote:a few days ago, the wiikey quit working all together. I tried everything, I knew my wiring was good, checked all the switches, all sorts of sd card formatting, etc.
Nothing was fixing it.
I decided even though it had worked plenty of times before with the "eject" switch on just ground and pin 29, hooking up 1.9v might be what the wiikey needs. One added wire, once pinch of potassium chlorate, one errant button press?
Ta-da. Wiikey works every time I press the button, first try. Pretty damn happy about that.
I suggest that, if you know your wiring is good, the blue light flashes in sequence with the "reading disc" message, you know your SD card is compatible and formatted right, and you can't get your Wiikey to work?
Try this next.
I suppose it could have something to do with the Wiikey itself, or it's compatibility with this cube. I never had this problem with my last cube, it might have something to do with the board revision because the IPL on this one is the same as my last working one.

Gamecube soldering points:
The soldering points depicted below are the above referenced Wii pin #'s. No confusing pinmatch required anymore.
Gamecube Motherboard DVD Drive connector. TOP of Motherboard:
Gamecube Motherboard DVD Drive connector. BOTTOM of Motherboard:
The power connections for the Wii DVD drive/WODE may be taken straight from the correct voltage pins on the GameCubes regulator board. For portablizing purposes the 12v power connector on the Wii DVD drive has been tested (not extensively) and confirmed to work with as low as 7.4v, it should work fine with Zenloc's custom regulator.
Power Regulator to Motherboard input (Rev A/B only):
Making the connections between the systems:
However you decide to make the connection between the systems a high gauge 24-28awg solid insulated wire type is recommended. IDE wire has also been reported to be acceptable. Keep your wire length to a minimum. Anything over 5-6" wire length may run into latency issues. To sum it up, the shorter the better.
1. (DVD/Wiikey/WODE) Currently the best connection option is to order one of the connectors listed below. This option allows you to connect the flat ribbon cable directly from the DVD drive/Wiikey Fusion/WODE and provides good sized solderable pads/thru holes to run your wires to. Depending on the interest shown in this mod emu_kidid may end up stocking one of them in the web store. http://www.proto-advantage.com/store/pr ... id=3400013 http://www.newhavendisplay.com/index.ph ... ts_id=2476 http://en.esskabel.de/adapter/datasheet ... 0-set/186/ http://item.taobao.com/item.htm?id=6598834882 + http://item.taobao.com/item.htm?id=5686938034 http://www.lcd-store.de/xaranshop_k014013s001_1.htm (You have to specify that you need 32 pins though). If you decide to use an FFC adapter that has too many pins you need to make sure that the pins are aligned correctly when you seat the FFC into the adapter! Check continuity from the end of the FFC to the soldering points of the adapter BEFORE you attempt to power on the system! You can kill your DVD drive/modchip very easily this way! After you've done this its a very good idea to secure the FFC in the socket in some way (hot glue, epoxy).
2. (DVD Only) The second method is to solder to the test pads right on the Wii DVD drive daughterboard. As you can see in the photo above each connection coming from the ribbon cable has its own test pad that can be soldered to. Since there are so many different revisions of the Wii DVD drive daughterboard you will need to do your own testing and confirm what pads go to what pins.
3. (DVD/Wiikey/WODE) The third option is to solder directly to the ribbon cable leads. This can be very precarious work and for long term use may not be reliable depending on your soldering skills. However it is do'able. The easiest way I found is to split every lead on one end of the ribbon cable with a razor blade and fold every other lead back to avoid bridging. Hold the bent back leads in place with some double sided tape placed beneath them. Tinning the leads before hand should aid in making a proper connection. The leads on the ribbon cable are very easy to burn through so make sure you use as little heat and contact time as necessary with your soldering iron. After confirming continuity on all pins covering the soldered end of the ribbon cable in hot glue or epoxy is recommended to avoid future broken connections. Here is an example of this method:
Other notes:
Before using your Wiikey Fusion on your GameCube you must set the region switch correctly! Else the GameCube will give you the standard error that you get when a Disc Drive is not connected to the Cube. Instuctions on how to set the region DIP switches on the Wiikey Fusion can be found here: http://www.wiikey.com/en/support/wiikey ... tallation/
When first connecting a Wiikey Fusion to a gamecube you will need to update it to v1.5 Wiikey Fusion firmware for it to work with the GameCube properly. This update can be done right on the GameCube, However you must have an SD card inserted at system power on with only the v1.5 firmware update on it for the Wiikey to boot properly and to recognize the SD card inserted. All Wiikey Fusions I've received so far have shipped with v1.0 firmware flashed to them, so this is required most if not all of the time.
The Wiikey Fusion has been confirmed to work with multidisc games using a SD card swapping method. When asked to switch discs simply swap the SD card to a SD card with the next disc .iso on it and flip/press your lid/open closed switch. There is however one other catch.
When adding games to SD card it seems that the Wiikey uses whatever "slot" the game is loaded to to identify what image to mount if the SD card is removed and reinserted during gameplay. So if on one card you have 5 games and on another card you have 3 games and the multidisc game you are playing ends up in a different slot than it is on the first SD card. The trick will not work. Ex:
SD card 1:
1. game x
2. game c
3. game v(disc1)
SD card 2:
1. game v(disc2)
2. game p
3. game d
This will not work! The game needs to be in the same "slot" as such:
SD card 1:
1. game x
2. game c
3. game v(disc1)
SD card 2:
1. game q
2. game p
3. game v(disc2)
This would work. I'm not 100% sure how WBFS manager arranges things on the card and why. Honestly the best way I can say to play a multidisc game this way is to just go buy two 2gb SD cards and put disc 1 on one of them and disc 2 on another.
For those of you who like to have a bit more of a visual guide/reference and are using the newhaven display FFC adapter, Beta has made up this nice clean diagram and shared it for everyone's use:
I ask that if you find this mod useful and use it please give credit where its due. Many months were sunk into getting all this working. Find master Zenloc and emu_kidid and toss them some thanks too
