I have an old version of neogamma installed on the wii as a channel. I tried to install a newer version, but it needs the SD card with neogamma on it to run(forwarder channel?). How do I install a permanent version on the wii (and remove the old version channel)?

I might go offtopic, but one game I tried (Prince of Persia - Rival Swords) PAL gives a flickering screen. Video fix patch on neogamma stops the flickering, but adds a green banner on the top and another on the bottom of the screen during play. Any ideas?
