One of the things with NDS game paging is that you need a class 4 or higher when dealing with roms with AP (as to why, I don't remember. but it was important enough to remember you needed something fast). In your case you would need something better than the lowest class.
The second link with the AP patch, you have to pick the one from the gba link to use or the one from the ds-scene link, you cant mix the 2 together. Even though they work on the AP, the patches are not compatible with each other.
