Hi mazin kaesra the link you put on your post is very interesting and seems to be a good one but still you would need a pc in order to use it for getting the software on to the sd card were as the floppy emulator your using the pc as a big storage device and loading straight off there oppose to swapping sd cards? I do this with the nintendo wii and the homebrew channel but it can be a pain taking the sd card out of the wii to take to the pc and then back again
There is a good amiga emulator for the wii homebrew channel
what ever you do these days with retro computers and consoles you need a pc!
