First off I'll give you information about my Wii.. It is 4.2u, I have everything installed and working fine.. so far.. I use Homebrew Browser, USB Loader GX and Configurable USB Loader is on there as well.

I'm not quite sure what IOS's I have.. is there a way to check? I followed the guide here: http://gbatemp.net/index.php?showtopic=171901

From the guide I put these IOS's on:

cIOS202[38+60]-v4.wad
cIOS222[38+37]-v4.wad
cIOS223[38]-v4.wad
cIOS249-v16.wad
cIOS250-v16.wad
Install IOS70-64-v6687[TB+ES_diV+NAND].wad

And I tested loading a game from USB and it's all working well.

I was really just wondering what all I have to do to get my Gamecube backups working? I know I can't run them off of USB drives, and that I need to burn them at 4x on good quality DVD-R, and that I can use USB Loader GX to boot the disc.. What I need help with is the MIOS thing.. I'm not quite sure if I need to put an MIOS, and if I do I'm not sure which one, and will I need to do anything else besides that?

Also, is there any ways to store Wii Menu Channels on my SD Card? Everytime I go to Data Management -> Channel -> and click on SD Card my Wii freezes, is there something that I should remove from my SD Card now that I am done installing everything? I'll put what my SD Card's file setup looks like right now in this spoiler:

I'm not sure what is ok to get rid of on my SD Card, and if anything that is on there is causing my Wii to freeze when I go to Data Management -> Channels -> SD Card

My last question pertains to the Snes/GBA Emulator.. where exactly would I put the roms for them to run, and is there any way to get channels for the emulators on my Wii Menu?

Thanks in advance for any help, I hope that by increasing my own knowledge and getting a better understanding of how everything works that I can maybe help some other people in the future.



EDIT:

I completely forgot about my two other important questions.

I am looking at getting a new Wii, but I remember reading somewhere that some of the new ones can't read DVD's so I wouldn't be able to play my Gamecube backups... is there anything I should look at for to classify whether or not the new Wii will be able to play backups?

I also am going to be getting a external hard drive.. any suggestions on what has good compatability? It seems like most of the WD externals work nicely, but I figured I would ask before I spend money.
