Nah it's ok NIXX
I was after a way to get a screen position on the TV...... so i could enter it in the source.
The way I do it is just overlay a grid over my images in photophop with 10px squares. The grid should be atleast 2px wide of else it won't show up on the TV correctly. Change the opacity of the grid so you can see your image through it. Then flatten and save the image to test it out on the Wii. Now you can get a good idea of what you need to move, and how far to move it. Once you have everything where you want it, just flatten the image without the grid and you're set.
If you are trying to find screen position to move around parts of the loader, just use the grid as a bg and count the lines on the TV.
Here is a basic PSD file that I use. It's 640x480 with a black grid 2px wide 10x10 set at 100% opacity. This means that every clear square is 8x8.

On a different note, I tried to compile the source from the link you just posted and got this error...
