Crate rsx_reader 

Readers for PlayStation 3 RSX graphics data: shader program containers (CgBinaryProgram, vertex and fragment), the fragment program microcode inside them, and the CellGcmTexture texture descriptor. All data is big endian.

The container reader keeps microcode encoded; it does not infer shader behaviour from parameter names. Everything a reader cannot read is an error naming the byte offset (see cgbinary::Error, fragment::Error). Layout sources and scope are in the crate’s README.

use rsx_reader::gcm::CellGcmTexture;

// A 24-byte descriptor: format 0xA5 (linear), 1 mip, 2D, a 256x128 image, identity remap.
let mut bytes = [0u8; 24];
bytes[0] = 0xa5;
bytes[1] = 1;
bytes[2] = 2;
bytes[4..8].copy_from_slice(&0xaae4u32.to_be_bytes());
bytes[8..10].copy_from_slice(&256u16.to_be_bytes());
bytes[10..12].copy_from_slice(&128u16.to_be_bytes());
bytes[12..14].copy_from_slice(&1u16.to_be_bytes());

let texture = CellGcmTexture::parse(&bytes).expect("exactly 24 bytes");
assert_eq!((texture.width, texture.height), (256, 128));
assert!(texture.linear());

Modules

cgbinary

Big-endian revision-6 CgBinaryProgram containers, with offsets relative to their own header. See the crate README for the layout sources and scope.

fragment

RSX fragment instructions. Words in the big-endian microcode are rotated by 16 bits before field extraction. Inline constants occupy one further slot. This reads instructions; it neither executes nor lowers them.

gcm

The 24-byte CellGcmTexture descriptor libgcm uses to describe a texture, read as data.
