I don't think thats important right now because you can still make a great game with the old models:)
Yeah, but it would be really nice when you can insert your own models, which would be a big difference to other games.
There are plenty of great hacks that don't edit GameFreak's tiles. And if they do they look like they were made by GameFreak.
It's more harder than 3G.
Because models (houses, buildings) and textures (grass, trees) are separate in the Map.
That's why i've made other modes.
For models, you don't need see anything.
But you can use the fantastic Yet Another Map Viewer, if you want. :)
Yes, for refresh in real time, but i don't know how i can do :p
