GTA Chinatown Wars - Camera hack
« on: April 10, 2012, 10:31:42 am »
Hello everybody,

I would like to know if anybody here ever try to hack / modify something in GTA - Chinatown wars (ds version) ?

Here is a screen of the game :



I think it would be nice to change camera angle of the game, to have something much more like previous gta games :



Since the game is not software rendered, I think it should not requires too much effort.

I dont know that much about DS hardware programming, but i think there is some projection matrix setup somewhere before 3D scene rendering. Changing some values there should do the trick ?

However, here is possible things that wont work :

- If rockstar decides to have that view, there is a reason. I guess one of them is limited power of DS. with that view, the game dont need to render a lot of things (frustrum culling). Changing camera view (with some code hack) will maybe show non-rendered areas. Maybe another hack somewhere will be needed to force DS to display everything needed.

- Maybe game will slowdown a bit after that change. But since the game run in emulator its maybe possible to fix that.

- Camera will maybe go inside some buildings / other polygons, like in games where camera is buggy.

- Some 2D sprites (and maybe other stuff) may not render correctly, because the view angle has changed.

or... maybe everything in the game is calculated from some camera angle (which already change dynamically while playing in the game if i remember correctly ) , so forcing it to be lower wont cause any of the problems stated above (except bad performance)

What do you think of the idea ?
As anyone already try this ? (for GTA CT or any other DS game)
