An SD card. Provided you didn't already update to 4.3, just follow the guide in the stickies.

 

You need a USB drive to play the games.

 

i have one last question before i mod. Once i mod it, i won't be able to return it back to it's original manufacturer warehouse quality correct?

 

updating to 4.3 would probably get you somewhat close to removing everything, but it won't completely get rid of all traces. You could also just burn your games on dvd-r's if you don't want to get a hard drive just for your Wii. (The hard drive has to be formatted to a special format type that won't hold anything but Wii games.) You could just partition the hard drive and just format the partition you wanna use for Wii and leave the other partition for other stuff though if you really wanna use it for other things. But also in order to play burned dvd's your Wii needs to be old enough. 2 years old might be old enough but that's like right around the cut off point so its not guaranteed.

 

Yeah, I got my Wii the first day it came out, so I'm quite sure it can run them, but I would suggest just using a USB. It is much faster and easier in my opinion. And what is the big deal with HCSD's? Mine hasn't had any problems.

 

All I need now is just how to get the games to run on a external harddrive. It's USB compatible but I'm just stuck in that stage of what to do. Also I haven't downloaded an actual game yet so I'll have to wait until I finish downloading one.

 

You need a usb loader application such as USB Loader GX on your SD card that you can run through the homebrew channel or have priiloader autoboot it on startup (use a forwarder dol for that though) Then plug your usb drive in the port on the Wii closer to the edge, not the one in the middle. If you want to use the drive for other things you can either partition it or format it to FAT32 and look up how to put games on that in .wbfs form. If you're just gonna use it for Wii games, you might as well just let USB Loader GX format it all to WBFS anyways. Then you can either just use WBFS manager to transfer games you download to the drive or you can just put a disc of the game you want to install in and usb loader gx will prompt you if you want to install it straight from the disc.
