I started to write this post out this afternoon but had to cut out of it quick so I want to do this now while I'm thinking of it. Everything's a-ok here, I just wanted to try to simplify a few things for everyone since there's going to be a TON of people trying to mod their Wii thanks to Xenoblade.
First off, I'd strongly recommend ripping the game, your physical copy of it to either an SD card or an external HD. Judging by how hefty and meaty that game is and the amount of time you're likely gonna spend with it, ripping to SD/external HD just seems like a no brainer and will keep your Wii's disc drive in good shape.
Secondly..and it's really important, make SURE you install IOS236 before doing anything else! You absolutely, positively NEED to install that in order to do the back-ups. Just looking at the Wiki page and some of this thread it seems like that might be a common problem people run into, so I can't emphasize enough to make certain you install that IOS before anything else, period. You'll save yourself a ton of headache and you won't suddenly be going "Uhhh I feel like I forgot something" later or be faced with errors.
Next, for the D2X installation..in the wiki guide the installation process looks long winded and complicated but it's really not. Once IOS236 is installed, all you'll do for the D2X installation is change a few numbers around twice and then you'll be good to go. Be sure to only change it to the numbers the Wiki says! DON'T screw with any other numbers, just the ones given. Also, it would be a good idea to download the already done meta.xml file for the D2X install, and make sure you replace the meta.xml file that comes downloaded with D2X with the already prepared one. Trust me, if you do that, install IOS236 first and THEN D2X you should have zero issues.
Finally, a few things about the configurable USB loader...
-Download the .zip file for the Cfg USB Loader from the wiki page.
-Then, extract that .zip file using 7zip, winrar..any of those will work.
-After extracting, you'll see a folder called Cfg_USB_loader_69.
-Open the Cfg_USB_loader_69 folder and you should see a inSDroot folder, along with license.txt and readme-cfg.txt files.
-At this point, open up the apps folder on the SD card that'll go into your wii.
-Once you're in the apps folder on the SD card, go back to the window with the inSDroot folder, and open the inSDroot folder.
-Next you're gonna see an apps folder and a usb-loader folder.
-Click on the apps folder, and you'll see one USBLoader folder..drag and drop that folder into the apps folder on your SD card for the Wii.
-go back to the window you copied the USBLoader folder from, and click back so you're seeing the apps and usb-loader folder. Finally, drag and drop the usb-loader folder into the SD card for the Wii.
-When it's all said and done, on the SD card for the Wii, in the apps folder you need to have both the USBLoader folder from the apps folder from the Cfg download, and the usb-loader folder copied over.
Clipper's guide is great, I'm certainly not trying to walk on him at all, the reason I mentioned all that is, if you just simply drag and drop the cfg_usb_loader_69 folder that you get after extracting over to the apps folder on the SD card, your Wii won't be able to see anything past that folder. It's a folder inside of a folder inside of a folder type situation that I want to help as many avoid as possible because it can be a frustrating headache to get it to where the Wii will be able to see it and just wanted to note all that here so anyone reading the thread can keep the amount of windows ya gotta have open to a minimum during the copying folders part.
Finallyyy..
-once you're in the actual cfg app itself, tell it whether you're using an external HDD or SD card..either way it should recognize whichever one you're using and it will then show partitions, asking which one you want to use. If you have lots of space on your SD card or HDD, you shouldn't need anything beyond your basic partition. Make sure whatever you're using, it's formatted to FAT32. With FAT32 formatting, you can have your games plus other files on the SD/external HDD without the need for completely reformatting.
-after that, you can put in the Xenoblade disc, and it will ask you to push A to open the DVD disc..it's just another term for ripping. It should open the disc and basically tell you it's Xenoblade Chronicles.wbfs. It should say it's 6.8 GB.
-Finally, push A to start the rip to the external HDD/SD card..if it starts ripping at that point you should be good to go, as long as your Wii's DVD drive doesn't crap out during the ripping. If you're gonna get any errors or it's refusing to rip the disc you'll get told that up front, it won't rip it. It will automatically create the WBFS folder that will be needed to store the game for you and will save it there so you don't gotta worry about that part
-Last note, the rip should take about a half hour to complete, go eat, run to the store real quick, whatever and it should be done when ya get back..when it's done, on a FAT32 formatted external HDD, it will tell ya it had to make 1 split to complete the rip. Don't panic, since with FAT32 it ends up with one 4 GB chunk and then another 2.8 GB chunk..layman's terms it's gonna cut everything down to smaller files so they can be easily accessed while playing. I hope this helps..again excellent job on the Wiki Clipper, I was really impressed! I just thought I'd try to simplify some of it for people.
