Well I'm not referring to making a demake. Rather, I'm saying that if we eliminated buildings from the equation altogether, since 3D models are a huge barrier to making DS hacking accessible, things would become a lot smoother on our path to mainstream DS Pokemon hacking.
Because in the DS games (BW most specifically), there's just so much that you can see that takes a good amount of hacking magic to achieve or just plain isn't possible. The possibilities in the capabilities that DS hacking holds are staggering, and while I'm not saying we should abandon GBA hacking (because that just won't happen), I really do think that we should start building an accessible framework for DS hacking so that we can create a more varied hacking palette.
