Sorry for the double post, but after looking at my explanation on the other thread, I thought this might warrant it's own.
Things you need:
Zelda: Twilight Princess
SD memory card formated for FAT16 and 2gigs or less (bigger than two won't work)
About 5 minutes
That's it. No hardward mods to the system at all. Though if you have the Nintendo Channel you may want to make sure that data collection is turned off. The HBC will record that you are using it in the wii's log (that message that pops up on the message board telling you how long you played what game). The only way ninty has access to that though is if you chose to share your data with ninty in the nintendo channel.
Anyway, you need a copy of Twilight Princess and an SD memory card to get started. You also need to have played TP atleast once so it's ticket is in the system's memory. Grab
http://wiibrew.org/wiki/Twilight_Hack and put the save that corresponds to your version of TP on the stick and upload it to your wii. If you have a TP save already back it up as you can't have two of the same game saves on your system. After you've copied it to the wii's memory, you only need to grab the boot.elf/boot.dol of the program you want. I recommend
http://wiibrew.org/wiki/Homebrew_Channel. Otherwise you have to run the zelda hack every time you want to load something.
There's a list of the different apps/emus/libs here.
http://wiibrew.org/wiki/Homebrew_apps/ The libs are cool for people who want to try coding their own project or port over to the wii. There's a surprising amount of emus out already. Most were ported from the gamecube with wii additions added (like using the wiimote). Unfortunately, a lot of the downloads on the wiki are out of date and/or lead to tehskeen.com to download the newest. Which you have to register for to download. A minor nuance I guess.
Once you have the save and the app you want, (take the HBC for example), rename it to boot.dol (or boot.elf. whichever version it is, make sure it's boot.whatever it came as) and place it in the root of the SD. Then put the mem stick in the SD slot and load the twilight princess save the corresponds to your version of TP (I had a release date tp, so I have to load TilightPrincesHack0 I think it was called). Once it's loaded, go talk to the man in front of you. This will crash the game and load the boot file you placed in the root. After it's done it will tell you to press A to reboot (if you are installing the HBC. If you are running an app, the app will just load). After it's rebooted, the HBC should be in the first open slot on your channel list.
I've been playing the Colosseum Chrono Trigger hack on the emu myself. I wanted to inject it directly into the VC, but to inject, you have to have a VC game that has a rom that's the same Mbit as the one you are injecting... seeing as the Colosseum hack makes CT a 48Mbit game, you can't inject it as the only two 48Mbit games were star ocean and tales of phantasia and neither of those are on the VC yet. You can inject smaller games by just adding blank data to the end of the rom before inserting, but not longer. In order to pass the SHA1 (I think it is) check, the wad files must be the same size as the one you took off the wii. It is explained much better between these two posts.

If you make an xml file (which you should be able to find examples of on the wiki) you'll actually be able to tell what your loading on the HBC. The HBC also supports network loading of .dol/.elf files. You'll still need a mem stick to load the roms themselves though. WiiLoad is the program for sending the HBC apps.
I've been having fun playing a port of Quake that was modded to have controls like Metroid Prime 3. :D
EDITED because the post somehow became extremely fubared
