i'm assuming it's new 3ds only because it's just that slow on the o3ds
Uh... yeah! It's totally not because I don't have a O3DS and have no way of testing on it. Hahaha.
But yeah, I think it's just safe to assume that O3DS doesn't have the processing capabilities that the N3DS has, especially with the other algorithms I'm planning on adding.
You should do quicksort or mergesort.
