GT4 Course Data

Applies to: GT4, TT, GTHD · Extension: None · Endian: Little

Tip

Refer to the Course Basics for some details about the terms used on this page.

The Course Data file holds all the contents of a track/course. It is split in multiple components making up a track.

This file is completely loaded into memory, and used in-place. It should not exceed 12mb in size (which is already 1/3 of the PS2's ram on its own!)


Size: Always a fixed 0x100 block.

Note

Most offsets can be set to 0 so that a component won't be processed.

Vision lists can be set to 0, everything will be rendered for the specified component at the expense of framerate.
