I edit the maps with google sketchup. Then I use 3ds max 6 or 8 with nitro plugins to create a .imd file. After that you must use G3DCVTR.exe and finally spiky´s tool. It is difficult but you must try it a lot of times!
I'm currently in the early stage of Littleroot Town's map model. I'd like to make it into a much more revamped map model that looks similar but different in design. And yeah, that would be fantastic if you'd like to help me, it surely would speed up the development process. ^^
I wonder... which area are you skilled at in NDS ROM hacking? 'Cause the area you're more skilled at... would be a good position for you in helping me. :)
Yep, I'm still focusing on Pokémon Lava Ruby, despite GameFreak developing the generation 6 games for the Nintendo 3DS (even though I don't know what they are yet). Which just shows... we're still quite behind in video game hacking, 'cause there hasn't been any exploit found for hacking the 3DS yet. xD
If only if someone had discovered a way to exploit the 3DS NAND... then we'd be able to hack the 3DS ROMs. Surely we would be able to modify the 3DS ROMs, but no one has even managed to develop a Homebrew app for the 3DS yet, nor has an Emulator been made. And even if an emulator gets made... 3DS ROMs cannot work without the Home Menu synchronizing with the ROM.
