Start accumulating vertices for a new primitive. `primitive_raw` is the raw GX command byte (e.g. 0x90 for triangles). `vtx_fmt` selects one of the

Maps a `TevAlphaArg` to its WGSL f32 expression string.

Maps a `TevColorArg` to its WGSL vec3<f32> expression string.

Finalize the current draw call and return the result. Returns `None` if no vertices were accumulated or if `begin` was never called.

Config path helper — matches gcrecomp-ui's config location.

Extract main.dol from a raw GameCube ISO/GCM disc image.

Read a null-terminated C string from memory at the given GC address.

Read a big-endian u32 from a byte slice at the given offset.

Set the input type for a single vertex attribute.

Allocate from the low end (grows upward). Returns GC address.

Compute facts for a single function from the slice of instructions that fall within `[func.address, func.address + func.size)`.

Reset all "has" flags and zero the staging data.

Read a zip entry into a Vec<u8>, enforcing the size limit.

Target frame rate based on timing standard.

Submit a 2-component f32 texture coordinate. Coordinates are appended to the first unused texcoord slot in the current vertex.

Allocate from the high end (grows downward). Returns GC address.

Maps a bias selector byte to its WGSL addend literal.

Submit an RGBA color for color channel 0.

VIConfigure

Convert RVZ to ISO via dolphin-tool, returning the raw ISO data.

Enrich every discovered function. This is the "function that adds info to the functions": one `FunctionFacts` per `FunctionInfo`.

Extract all files from a disc image's FST and write a GCFS archive to game/assets.bin. Returns the number of files extracted.

Extract main.dol from an RVZ file by converting to ISO with dolphin-tool.

Pack the current vertex into the flat `vertices` buffer and reset the staging area for the next vertex. The layout written per vertex is: position (3

Get the full 64-bit timebase counter (OSGetTime).

AIInit

Decode real instruction words so the test exercises the same `raw`/`address` fields naive discovery keys on. 0x4E800020 = blr; 0x38000000 = a non-retu

Maps a `TevOp` to its WGSL arithmetic symbol.

OSInit - Operating system initialization. Sets up the arena allocator, timer, and interrupt system.

Large function - don't inline

Parse a u32 from decimal or `0x`-prefixed hex.

Maps a `TevRegId` to its WGSL variable name.

Maps a `TevScale` to its WGSL multiplier literal.

Sign-extend a 26-bit branch displacement (`b`/`bl`, the `LI` field).

Validate that uploaded data looks like a DOL file.
