I've looked around this forum for a few weeks now and a lot of poeple here don't know that much about Wii Modchips. So I'll try to make a little FAQ, which I hope will help them. I don't know how good it will turn out, but I believe it's better than nothing and maybe it will become something one can simply link to when asked. So let's begin Part 1: Deciding on a Modchip 1. What modchip should I get? Well it depends. There are different revisions of the Wiis DVD-drive on which the modchips are installed. Specifically the drive-controller has changed a lot, which is the small controller on which (or near which) the modchips are installed. You will see it in any modchip diagram. Here are a few pictures of it: http://www.wiidrives.com/formhelp#controller The following revisions exist: D2A, DMS, D2B, D2C, D2C2 and D2E. It is written on the controller itself which one it is, so you won't know for sure until you open up your Wii. But you can guess which it is by going to www.wiidrives.com and checking your Wiis serial number there. If you have a D2A, DMS or D2B with uncut legs proceed to point 2. Otherwise, if you have a D2B with cut legs, D2C, D2C2 or D2E proceed to point 3. There are very rare cases where the legs of the drive-controller are covered in Epoxy (black glue). In this case refer to point 4. 2. I have a D2A, DMS or uncut D2B drive. What modchip should I get? The answer to this question is pretty easy: YAOSM. YAOSM is a great chip, it's the best for those drives and it's open source, which ensures that you'll get an update should one be needed. (unlike wiikey for which the support was dropped moths ago) Some people will argue, that this PIC-based chip is much smaller than others based on ATmega8s, like the wiikey or OpenWii. Well you have heard it often enough and it was never true, but in this case it is: Size doesn't matter. On the recommended PIC-chip YAOSM has _lots_ of space left. I could get more technical, but I don't want to confuse anyone more than neccesary. Furthermore YAOSM has the best disc-detection of all the chips for these drives. It is better than the one of wiikey and far better than the one of OpenWii, which is just crappy. I know this statement will attract a lot of flame, but I know what I'm talking about. I've been around since the first Wii chip came out and have myself been through Chiip, OpenWii, Wiikey and YAOSM, not to mention the contless threads I've read. To get OpenWii to run you'll probably have to tweak the hell out of your Wiis laser which will shorten it's life span. Ofcourse you could be one of the lucky ones for which OpenWii just works but are you willing to bet your money on it? Ok enough of OpenWii. Why not Wiikey? I mean everybody is talking about it, right? Well popularity isn't allways a sign of quality. I was originally going to tell you an example from history but all I come up with are pretty disgusting, so I'll just skip that part. In short the disc detection is worse than YAOSMs, there are a few bugs in the latest firmware (mainly regardings the GC audiofix) and support was dropped a long time ago (and even before it was dropped it was shitty). Let's get away from the chips you shouldn't get and back to the one you should. A nice thing about YAOSM is that you can build and program it yourself for about 3-4$ including the parts for the programmer. All the details can be found here: http://wiinewz.com/forums/yaosm/ If you are not that good with electronics you can buy it preflashed, for example from eurasia. In case you want a solderless solution you can get a Free-Clip and flash YAOSM on it. The only place I know of that sells them is dealextreme ($25) and sadly I don't know a place that sells them preprogramed, so you'll have to do it yourself. But on the bright side, it's a pretty easy process and all the parts needed are includet in the package you buy (no soldering needed, just a PC with a COM-port to flash it). The best thing about this chip is, that it is Open Source and so will allways get updates if needed. Even if Bell (the creator of YAOSM) stops working on it, everyone who can code can pick it up and make updates. Some people will tell you that YAOSM isn't updateable via DVD. That isn't true. Since version 3.0 YAOSM stores it's drivecode in the EEPROM-area of the PIC-chip, which is fully updateable, via DVD. Only the code that patches this drivecode to the drivecontroller is stored in the non-DVD-updateable part. Thing is, since YAOSM can allready patch D2A, DMS and D2B drive-controllers, this part of the chip will never, ever need updates, so you are golden. The part that may need updates in the future, due to new Nintendo protection or whatever, can be updatet via DVD. Just the part that won't need updates ever can't. Everything else there is to know can be found in the official YAOSM FAQ: http://wiinewz.com/forums/yaosm/67369-yaos...read-first.html 3. I have a cut-leg D2B, D2C, D2C2 or D2E. What modchip should I get? Well this is going to be a lot shorter: It doesn't really matter. All the chips for these drives are and do basically the same. Chips that I know are good and can recommend are: Wasabi, D2Sun, Wiikey2/D2Lite. Those are all original chips (no clones) that work great. None of these works better than the other so it doesn't really matter which one you get. I really can't comment on the other ones, except that I wouldn't recommend the D2Pro anymore. As it probably won't be supported anymore, now that the team has moved on to wiikey2. However, this is no reason for existing D2Pro users to panic. Your chip will probably continue working forever. If you want a solderless solution, just get one of these chips presoldered to a corresponding wii-clip. They are availible from many locations and resellers. 4. My drivechips legs are covered in Epoxy (black glue). What should I do? Well sucks to be you right now. A lot of the points needed to install a modchip are covered up, so you can't solder to them or get a wii-clip on there. The only way to install a modchip on these drives is to remove the epoxy, which can only be done by a Pro. So grab your drive and send it in to get chipped. To know which chip you should let the modder put in there, refer to point 3. Part 2: Other questions 1. So I've got -insert modchip name here- in my wii. Now what? Throw in a game or a backup and play it. (For some modchips you have to insert a game that has the same region of your Wii to set the modchips region first, for example YAOSM, D2Pro, Wiikey2. You'll probably find it on your modchips website if it is necessary, but it can't hurt in any case ) 2. How can I back up my games? There are special LG-drives for your PC and a tool from Waninkoko with which you can back up your games. To learn more about them use the board search. Other ways to obtain a backup are illegal and therefore won't be discussed here. If you can't google for them, get of the internet. 3. So I just backed up a game. Burn it to disc, and pop it in the wii and it'll play it? Yep pretty much. But don't use a crappy Laptop burner to burn the game, update your burners firmware and use good media, like Ritek, Verabtim or Taiyo Yuden 4. I hear wii scrubber, trucha signer, brick blocker, regionfrii, what are these? Should I use them? No. This tools aren't really current (except turcha signer, but you only need it if you are a Pro and then you wouldn't need this FAQ ). If you want to play imports or backups of imports on your Wii just use GeckoOS (use google). 6. Can I still play my bought wii games after I installed a modchip? Yep, just like before. Well I hope this pretty short FAQ helped a few people... Questions, critic? - All welcome.
