Yes it is possible. A lot of those hacks you mentioned require an SD card with relevant files in place.
Preloader is the screen you are seeing when you boot your Wii.
1. Does The Homebrew Channel appear in your Wii Main screen?
2. The SD card will require the bootmii folder, this can be obtained by running hackmii installer again (can also apply to 1.)
3. Unsure about this one
4. No SD card, no file to launch. This function allows the user to load a chosen homebrew file without entering HBC or the Wii menu. It is not required for normal use.
5. No SD card with hacks.ini to read. When you load your SD card you'll need to locate a hacks.ini for 4.1.
You may need to reinstall, check the tutorial http://www.wiihacks.com/recommended-...d-any-wii.html as this will provide you with all the files you need, a working HBC install, preloader and hacks.ini, neogamma (backup launcher), cIOS and everything else recommended.
