Icon getters: we ship no trophy icons. The two-call protocol is size-query (buffer == null -> write the byte size) then fetch (buffer != null -> fill)

Copy guest pixels (32bpp RGBA) into `img` via a staging buffer. If the source surface is GCN-tiled (tiling not linear), de-tile into a linear scratch

DELTA_AVP_TRACE: count calls to the hot AvPlayer entrypoints. If a title spins on IsActive/GetVideoData (millions of calls) it is WAITING on the movie

Walk the rbp frame chain (guest code keeps frame pointers) and symbolize each return address. Bounded and range-checked so a bad frame can't loop or f

Begin a dynamic-rendering region binding mrtCount color targets (mrtBase[0] is the primary). The common single-RT case (mrtCount == 1) binds exactly o

Decode CB_BLEND0_CONTROL into a Vulkan colour-blend attachment. `en` is the per-target blend enable (bit 30). Falls back to a sensible src-alpha blend

Full bring-up against the current g.window: instance, android surface, device, command/sync objects and the swapchain.

Build a 64-byte DS4 USB HID input report from the keyboard adapter (or neutral). Layout: [0]=reportId, [1..4]=sticks, [5]=dpad+face, [6]=shoulder/ sys

A CPU "relax" hint for a spin-wait: no syscall, no context switch. The guest scheduler (e.g. Doom64's KEX parallel-job manager) busy-waits for a worke

DELTA_AVP_TRACE: dump the init-data block as 16 pointers so the event-callback (a guest code pointer) and its offset can be identified -> lets us fire

SCOUT: patch a guest function to `xor eax,eax; ret` (return 0). Used to step over libkernel-internal validation that rejects our externally-loaded mod

Per-module HLE policy. We prefer running the real sprx (LLE) for modules whose syscall/device backing we emulate, falling back to the HLE shim only wh

Read cbuffer dword k (== uvec4 data[k>>2][k&3]) as a uint Id. Clamp the uvec4 index into the 64-element (1 KiB) window so an out-of-range constant ind

Pixel index within an 8x8 micro tile for 32bpp (matches tiling.comp). Display: x0 x1 y0 x2 y1 y2 ; Thin/Depth: x0 y0 x1 y1 x2 y2 (Morton/Z).

Type-3 IT opcode.

Keyboard->DS4 adapter, laid out for two-handed keyboard play: the left hand moves (WASD) and works the action keys, the right hand aims (arrow keys).

Read a well-known outer-PKG metadata entry (param.sfo / icon0.png). These sit in the PKG header table, not the inner PFS, so they read even for pkgs w

Resolve a sampled texture address to the live RT image that backs it (the resource model's "the page table collects all overlappers" lookup). The game

RSA-2048: m = ct^D mod N, then strip PKCS#1 v1.5 type-2 padding (like the Python _rsa()). Returns the recovered payload, or empty on bad padding.

Minimal param.sfo reader: returns the value of `key` (UTF-8 string keys, or int32 keys rendered as decimal), or "" if absent. The SFO is a small flat

Start the 60 Hz EVFILT_DISPLAY pump once, on the first vblank registration, so the timer thread only runs when something waits on it.

Resolve a host address to "<module>+0x<off> (<seg>)" by scanning the loaded module images, so a guest fault points straight at a guest module offset.

Tear everything down (window lost). The guest GPU renderer has its own Vulkan device, so dropping ours only stops presentation; it resumes on re-init.

Cheap content fingerprint of a guest texture: sample a spread of dwords. Lets us re-upload dynamic textures (room art composed/loaded after first samp

Image view for a guest texture (ensures it is cached/uploaded via getTexture).

A low-bit TSC nonce for the display event's bits 0..11, so a polling title sees each event as new. On the native x86 backend that's the real rdtsc; th
