A couple of questions involving Wii Memory

I just want to make this clear. I already installed Homebrew Channel and a couple of wads.

When I attempted to play LoZ: MM and a few other games on my SD Card, it said 'This channel could not be launched. Manage your Wii System Memory to launch this channel. I don't understand; why would a game from the SD card need space? I already have enough space too, I don't think saves are 100 blocks, but thats how much is left on the menu. Also, aren't saves normally on the SD card alone? I'm confused, the games on the Wii Menu all start up as well. Also, the SD card has 1133 blocks open.

In the background, to launch channels from the SD it copy's them to the Wii. Move one or two to the SD and it'll work OK.

You need more blocks open in your Wii's Internal memory.

How many? I can clear some up, but a lot I wanted to already get started on.

As many as the size of the channel youre trying to launch.

Never mind Arik, thanks for the help. I figured I'd delete the wads I hadn't installed yet and move the games I already installed onto the SD, thanks to the space I got when I deleted those wads.
