Things We Know About Modding LR

[Fluffy Cupcake]

Here is a list of what I know is possible to do in LEGO Racers.

Can Do

Extract and recompile the JAM archive
Roughly modify all audio
Modify all textures (tracks, objects, characters, you name it!)
Modify the strings
Modify almost all files in a binary fashion (pain in the butt for certain things, but it is still better than nothing regardless). This includes:

AI Routes

Animations
Checkpoints
Circuit Listing (Add/remove circuits [unconfirmed], unlock sequence, which AI racers, and how many AI racers)
Cutscenes
Hazards
Friction By Surface
LEGO Bricks List
Loading Screen Layout
Materials List
Menu Interface Layout
NPC Car & Driver
Object Positions
Skeletons
Skybox Gradients
Start Positon
Race Listing
Texture List
Track Header (files to load when launching track)
+More Unknown

Visually edit Powerup Locations
Record/Create Ghosts Paths
Change the vertex colour on a model (even tracks) to complete white. (Will made and sent me a tool when I requested, due to vertex coloring ruining a track when I tried to texture edit it)
Beat this game in one sitting (this is a joke)

 

Cannot Do

Make custom models (tracks, objects, etc). We are lacking the tool(s) to do so.
Change functionality of powerups
Change gravity physics (if you can, this hasn't been found yet. Friction was found, so maybe this is out there somewhere like it is in LR2.)
Go past 30 bricks in the Bricks Listings

Go past #(?) of minifigure pieces limit.

By all means help me out with this list! I get a hunch I'm missing some things from the cannot list.

Correct me If I'm wrong, but I believe there is also a hard limit on the number of Minifigure pieces that are selectable in driver creation, in addition to the hard limit of 30 bricks per category in the car builder. I don't remember the exact number, but I believe it's the exact number of stock pieces, meaning you can't add new ones without overwriting any.
