Opening/Soldering the WII Guide | Updated 2/26/2007 Ok, it seems a lot of people are afraid to solder, so I'll tell you everything you need to do / buy to install a modchip in the wii. If your like me you don't want to waste money cause its hard to come by. So listen up, This is the poor man guide to doing this yourself for around 20 bucks. Divided into 4 steps Step 1: Gather tools needed Step 2: Gather soldering tools needed and begin practicing Step 3: Get a modchip Step 4: Getting your backups ready to play. Step 1 - Gather hardware needed to open case To open the wii you will need: *A Cutter tool (to get the little white stickers off the screws) *A Very Small Phillips Head Screwdriver (should already have) *A Tri-wing driver ( Search Ebay, the same ones that fit NDS/GB work on the WII, 7 shipped usa, or call hardware stores) Please note: I got this tri-wing driver and it worked for all the security screw except the ones holding the faceplate. I believe those need a tri-wing driver size 1, and the ebay driver is a 3. Watch THIS video. Its hosted on youtube and is the best out there right now. you will only have to do steps until the 5:50 mark. The dvd drive he pulls out is where you will be soldering onto. Step 2 Gather hardware needed to solder Buy the following: * RadioShack 15-watt soldering iron CAT 64-2051B or newer model (10 bucks or less) Or Buy THIS one from Radio Shack $8 and includes everything. * Rosin-Core Solder .015 diameter 64-035 (USE rosin-core only!! and .015 is great for the wii) HERE is the one I bought. * 30 AWG Wire here. The smaller the wire the better. Step 3 Picking out your modchip Many options are out right now, but these three are talked about the most: 1) The Wiinja. $30 US Dollars, 5 wires to solder. A newer model was announced today that is upgradable via DVD. Wiinja installation video. It's in spanish, but it gives you an ideal of what the process involves. The first modchip released for the wii, its main selling point is playing wii backups from your own region. 2) The Cyclowiz. NOW UPGRADABLE via DVD. $40 US Dollars, 0 wires to solder (quick-solder) Cyclowiz installation video by maxconsole.net. Its brief but still lets you see them putting the chip in. The second modchip released for the wii, definately being promoted by maxconsole.net, its main selling point is no wires to solder, but it will be a pain to remove if you want another modchip. Both of these modchips support booting WII iso's from the wii's region. The wiinja is not upgradable. I have this modchip and am writing a review on it now. It boots all my NTSC backups fine except COD3. 3) The WiiKey. Cost Unknown, 4 wires and quicksolder The newest chip to hit the market is the WiiKey, it's main selling point is that it supports upgrades via dvd-r and will play all NTSC/NTSC-J from a NTSC console. Since it contains upgradable firmware we can expect a region free firmware update soon (hopefully). We will know more about it shortly. Right now , I'd keep waiting. Lots of mods/clones have hit the market the past week. I'd see which is the best. Misc Info on the PIC that wiinja uses HERE is the PIC I believe they are using, its the PIC 12C508A. Its only worth about 4 bucks, and you need to program it with the dump of the wiinja. I bet someone will be selling these for $15 right after the wiinja gets released. You also must realize the Wiinja is selling the few lines of codes for $30 and not the chip. So thats why the wiinja cost so much, I'm not saying its right to charge that much. Step 4 Getting your backups ready to play After you acquire your backup, check the following: If it's 4 699 979 776 bytes, it's unscrambled. If it's 4 700 012 544 bytes, it's unscrambled with unscrambler 0.4 which adds an extra 32 768 bytes to the file (JESUS release) If it's 4 736 698 368 bytes, it's in raw format and must be unscrambled with this tool. (thanks to niklasnyfiken for this info) After your backup is unscrambled, simply open nero and burn the image to dvd. (The wiinja team has confirmed nero is ok) I recommend using Verbatim 16X DVD-R. Misc Soldering Info Look at the diagrams over and over until you know 100 percent its right before you do it. Don't be afraid to mess up, cause you can fix most of the time by a copper braid and/or a desoldering pump. I will go more into detail about this later. Use a old network card/cd player to practice and before long you will installing modchips no problem. I recommend reading THIS guide as it is what I used to learn. Below is a pic of what a good solder joint look like, basically you want a "volcano" as it will last YEARS and YEARS. . If you still need help: I will be documenting me taking apart the wii, (and installing a modchip, after the clone comes out, or I get a sample to review). I will also answer any question as best as I can. Be fun, be safe and enjoy your WII.
