Glad to see Di/Pe/Pl getting hacked. I always look at what could be done when I play the game. Like a remake of Pokemon Emerald :)
Yeah, as we're always seeing more improvements on hacking the Nintendo DS games. I'm possitive that it will continue to improve even more, so people will be able to bring their imagination to life, and produce the 3D objects and even change alot of things in a game. And with ROM Hacking... anything's possible with editing game. So it doesn't matter what the console is... as long as we've got a ROM, we'll be able to research and edit it.
We can all help... and learn how to edit a ROM, and then create a program that will indeed edit stuff in the game. Like for instance... a map editor getting made for the 4th generation. And yes, it's not like it's hard or anything... but it can be complicated and can take quite a long time to do. Because you have to research the ROM while editing the hex to see what it does and all that, then once you've learned, then you make the program allowing to edit it, and also... it has to read the content that is compressed in the NDS file. Using Cristal Tile 2 (even though it's in Chinese), you can click the Nintendo DS icon, it's on the same row as new file, open file excetra, just look for what looks like a Nintendo DS and once you've clicked on it, you'll see what there is in the contents, so it'll make life a bit easier when looking for files to edit and stuff.
If you're wait for a map editor... and you still want that urge to edit an NDS file... it's always best to give it a try. ;)
Even if I haven't yet... I'm sure to try and learn how to hex edit and understand the values of the objects and stuff, once I do learn how to do it, I'm sure I might be able to create my map editor for the fifth generation, aww yeah! :)
