Read a save into `buf`. Returns the payload length. Transparently decompresses if the save was written with [`Card::write_compressed`] (requires the `

Add one sample. Returns a log line when `PSOXIDE_PROFILE` asks for stderr output.

Reset this thread's GTE to a freshly-zeroed state. Convenient at the top of a render frame where you don't want stale FIFO contents from the previous

Reset history to silence between XA files.

Apply an interactive rotation delta about one axis to an authored Euler triple and return the new Euler triple. `Global` composes the delta in the wo

Walk `root` recursively and update the library in place. For each file whose extension matches a known format: - If the cache already has an entry wi

Accumulate point lights at `point` and modulate `base` by the resulting light RGB.

Snap a requested World sector size to a positive 128-unit grid.

Submit a projected textured triangle.

Flat tint used by non-Gouraud textured primitives.

Decode a VRAM rectangle into an RGBA8 buffer for display. Full-range 5-to-8-bit expansion: `(v << 3) | (v >> 2)` maps 0→0 and 31→255. The naive `v <<

Return as `(r, g, b)`.

Try to send a command and capture its first response packet. Returns `None` if the controller does not expose parameter room or a response within `sp

Unpack the low/high halves of a packed XY word into two `i16`s.

Current facing yaw.

Append a fresh UI scene named `name`, seeded with an empty root Canvas at the PSX 320x240 authoring resolution, and return its freshly assigned stable

Plug a memory card into port 1 with the given backing contents (128 KiB buffer, typically loaded from a `.mcd` file). Pass an empty `Vec` to start wit

Convert a BCD byte back to binary. Inverse of [`bin_to_bcd`] for well-formed input; nibbles above 9 are not normalised (the drive never emits them).

Snapshot of the allocated grid rectangle + cooked-byte estimate. Use [`Self::authored_budget`] when empty capacity should not count as room footprint.

Advance the LRU clock. Call once per cache cycle (e.g. per frame) so `get` touches and eviction comparisons share a monotonic timeline. Never returns

Stop the live sector stream and strip any queued DataReady work from both the pending queue and ACK followups. Redux cancels the read interrupt source

Ceiling diagonal split id.

MAC0 32-bit overflow check + truncation.

Convert a binary/ascii FBX file into native model/animation/texture blobs.

Cosine in Q12 fixed point.

Mutable counterpart to [`Self::current_ui_scene`]. Reads the clamped index by value first so the mutable borrow is purely `&mut self.project`.

Bit-exact Gouraud-shaded triangle dispatch: silicon-matched DDA coverage + determinant-plane RGB interpolation.

Draw the burn submenu opened from an example/project row.

Enable a channel in `DPCR` without disturbing the others.

Enable per-pixel command tracing. Allocates the 2 MiB owner buffer (one u32 per VRAM pixel). Every subsequent `plot_pixel` stamps the currently-execut

Shared exception-entry sequence. Mutates COP0 registers and stages the exception-vector PC for [`Cpu::step`] to apply. - **CAUSE**: *overwrite* with

Fetch the current voice's interpolated sample. This mirrors Redux's `spos` + `StoreInterpolationVal` flow: consume decoded samples into a rolling 4-sa

Textured polygon header with the material's flat tint.

The four corner UVs (texel coords) of a glyph cell whose top-left is `(u, v)` and size is `gw × gh`, with the far edge **saturated at 255 instead of w

GP0 0x02 fill rect (direct VRAM; ignores draw area/offset/mask).

Run the GPU rasterizer for one mono-tri with the given flags onto a pre-filled VRAM, return the post-dispatch full VRAM.

Flatten the hierarchy into display rows.

X/Z position of a horizontal face corner in editor convention: NW/NE live on the high-Z edge.

`true` when there are zero hard errors.

Path to `library.ron` (machine-generated scan cache).

U origin in texels within the selected texture page.

V origin in texels within the selected texture page.

Universal coincidence resolver. Returns the physical vertex containing `seed` -- every face-corner whose current world position equals the seed's worl

Mutable access to port 1 -- lets higher layers swap a memory card in while keeping the pad attached.
