WHEN YOU TRY TO SWAP DISK ON THE WII, THE WII WILL JUST RESTART!!! NOTE: There are download links all throughout this post but if you just need the files you can go to the end of this post, to find what you need. I just received my SD Media Launcher (1gb), with some time and tweaking, I am finally running a back-up of my Zelda Twilight Princess. Goal of this thread is to help with the following: - How to use your SD Media Launcher - A place to get everything you need in one thread (Downloads) - How to take your Gamecube apart. - Show you how to do the Laser "POT" Tweak and How much to Tweak it, is based on your model of your Gamecube. So lets get started!: How to use your SD Media Launcher Step 1: Ordering your SD Media Launcher Well first you have to order your SD Media Launcher from Datel You have two choices 1 Gig Version Or Two Gig Version Does not matter which one you get. Order it and it should take a 10 days or less to get to you. Step 1 1.5: Getting your DVD-R While you wait go get some Mini-DVD-R (THEY MUST BE DVD-R) Top Mini-DVD-R are: Ritek Ridata Mini DVD-R 4x (Really popular) FujiFilm DVD-R (Worked really well for me) DVD-R CMC (Heard good thing about it) To the Picture A good price for Mini-DVD-R should be around 50 Cents - 60 Cents a Disk. A good place to buy your Disk from: SuperMediaStore CDRDVDrMEDIA Replacement Top is another way to go if you don't want to trouble yourself with the Mini-DVD-R. Just get DVD-R and it should work the same way. Good place to get your Replacement Top is at: Interesting-devices Step 3: Your Package Arrives When it arrives it should look like this: To the Picture Checklist: A SD Media Launcher SD Card Reader 1gb or 2gb SD Card The User Manual SD Media Launcher Disk (Its inside the user manual) Step 4: Downloading the GCOS GCOS = GameCube Operating System Download the most recent version of GcoS (Currently 1.X beta). You can get 1.X beta from GCOS 1.X Beta. Or get the 1.5 GcoS from here GCOS 1.5. Extract it to a folder. I had more luck the with 1.5 so I am using the 1.5 on my Media Launcher. Step 5: Putting your GCOS on your SD Card Plug in the USB 2.0 Card Reader and the SD card. When your computer reads the SD Card, Drag and drop the GCOS to your SD card. File Name: If you are going to use version 1.5, then the file name will be: GCoS 1.5 (PSO).dol If you are going to use version 1.X Beta, then the file name will be: gcos1.x.dol Step 5: In to the Media Launcher. Unplug it and take the SD card and put it in to the Media Launcher. To The Picture Step 6: Putting your Gamecube game Back-up on a disk. Before burning make sure your Back-up Rip should exactly read 1,459,978,240 bytes.(1.35GB) It does not matter if its a 50MB game. If it is not that size, that game will not work, but you can use a program called: Wiped GCM Fixer 1.5 (This program will help make it to that size.) If the back-up is a .gmc file just rename it to .iso. Download here: Wiped GCM Fixer 1.5 Finding a back up of your game is one step you have to do on your own. But when you find that back-up you should use a program called Imgburn. Its free and very easy to use, + It works! Download Here: Imgburn Imgburn: 2x Speed Burning If you are a Nero user: Extract your iso and burn it with Nero. If you get a .gcm file, rename it to .iso and burn away with Nero. I had some problems with Nero but when I reburned it with Imgburn it worked. Nero: 2x Speed Burning Step 7: In to the Gamecube Now Plug in the Media Launcher in to memory card slot 1 or slot 2. Then put the Media Launcher Disk in to the Gamecube. To the Picture Step 8: Turning it on Turn on the gamecube. You will see the SD Media Launcher screen pretty quick. Now you should be at the main screen. Select the GcoS 1.5(PSO).dol file and press start or if you are using Version GCOS 1.X Beta: click on gcos1.x.dol. and let it load. To the Picture To the Picture Step 9: GCOS Now you should be at the GcoS main menu. Select the Boot Game option, from here on in it's pretty simple. It will tell you to swap your game so open up the lid and put in your backup. After this, it will detect the game, and give you 3 loading options. To the Picture To the Picture -If your backup is the same region (PAL or NTSC) as your gamecube, just choose the Autodetect Region function (Press A) - If your backup is differently region coded than your gamecube (IE PAL game NTSC Gamecube) force loading for the region of your gamecube (X or Y depending on your region, IE if you have a PAL gamecube force load as PAL). Step 10: Have Fun! Step 10.5 (NOT ALWAYS NECESSARY): Did you follow this tutorial to ever step, yet you have one of the following problems: * Game Wont Boot * Game TOC Loads, but fails to boot (You get the Cube setup screen) * Onscreen Error "Can't read disc, etc" (Most Common) * Onscreen Error "Refer to instruction manual, etc" * Random Game Freezes * Choppy Movie Playback * Black Screen of Death ?
