PSP uses PSPGL -- a library that *emulates* GL on top of -the PSP's native GE/GU hardware, which is entirely different underneath. - -Problems this creates: - -**PSPGL is a lie.** The PSP has a native graphics engine (GE/GU) with its -own command list, its own vertex formats, and its own display list model. -PSPGL translates GL calls into GU calls, but imperfectly -- and we end up -paying the abstraction cost without getting GL correctness. Writing directly -to GU gives better performance, access to native formats, and correct -behavior on edge cases that PSPGL gets wrong. - -**Legacy GL should not share code with modern GL.** The fixed-function -pipeline (no shaders, matrix stacks via glMatrixMode, glTexEnv) is -meaningfully different from modern GL (VAO/VBO, GLSL, explicit uniform -locations). Treating them as "the same thing with a flag" creates a tangle -of `#ifdef DUSK_OPENGL_LEGACY` guards throughout the rendering code. -They are separate targets and should be separate platform directories. - -**Saturn cannot fit the model at all.** VDP1 is a command-list processor: -you write 32-byte command structs (sprites, quads, lines) into VRAM, then -poke a register to trigger execution. There are no vertex buffers, no -shaders, no Z-buffer. Depth is pure painter's algorithm -- command order -IS the depth. VDP2 composites up to 6 background planes at scanline time; -these are tile maps and rotation parameter tables, not meshes. Nothing -about the current API maps onto this hardware. - -**SNES is even further removed.** The PPU renders tiles. VRAM holds 8x8 -or 16x16 pixel tiles and tile maps; the PPU references these during -scanline rendering. There are no draw calls. Mode7 is an affine transform -applied to a single background layer (the basis for the overworld map and -road perspective effects). Sprites are entries in OAM (Object Attribute -Memory). The 65816 CPU writes to memory-mapped registers and VRAM; the -PPU does the rest. The concept of "mesh" or "shader" is meaningless here. - -**Textures loaded as RGBA waste memory and exclude platforms.** Loading -every texture as 32-bit RGBA and converting at runtime is expensive on -memory-constrained platforms (Saturn has ~1 MB total RAM; SNES has 64 KB -VRAM) and simply wrong for platforms that have native formats incompatible -with RGBA (e.g., PSP's ABGR8888 / BGR5650, Saturn's RGB555 / CI4 / CI8, -SNES's 2bpp/4bpp/8bpp indexed). The asset pipeline must compile textures -to platform-native formats at build time. - -**UI in 3D space is wasteful and limiting.** Currently UI elements are -rendered as geometry projected into screen space, going through the full -3D pipeline. On platforms with dedicated 2D hardware (Saturn VDP2, -SNES BG layers), this is actively wrong -- UI should map to a hardware -plane, not a 3D draw call. On modern platforms it should be a clean -screen-space pass that never touches the 3D depth buffer. - ---- - -## Current Model (Summary) - -``` -Scene - -> shaderBind(shader) - -> textureBind(texture) - -> meshDraw(mesh) <-- immediate draw call per object - -> meshDraw(mesh) - -> ... -Platform receives each draw call immediately. -Depth is handled by Z-buffer hardware. -All textures live in GPU memory as RGBA (or Dolphin's tiled RGBA). -UI is rendered as 3D geometry with an orthographic projection. -``` - -Key current concepts: -- `mesh_t` -- vertex array (triangles/quads), in GPU VBO (GL) or CPU - memory (Dolphin) -- `shader_t` -- GLSL program (modern GL), GL fixed-function state - (legacy GL), or GX matrix + TEV config (Dolphin) -- `texture_t` -- GPU texture handle (GL) or tiled CPU buffer (Dolphin); - always RGBA at the engine level -- `framebuffer_t` -- FBO (GL) or fixed hardware XFB (Dolphin) -- `spritebatch_t` -- accumulates 2D quads and flushes in batches of 32; - the only existing deferred-submission system in the engine - -The spritebatch hints at the right model.

See UI System section below. - -### Platform translation - -| Intent | Modern GL | PSP GU | Saturn VDP1 | PS1 OT | N64 RSP | SNES PPU | -|---|---|---|---|---|---|---| -| QUAD | VAO + glDraw | GU display list | distorted-sprite cmd | GPU quad packet | RSP display list | OAM + BG tile | -| POLYGON | VAO + glDraw | GU display list | polygon cmd | GPU poly packet | RSP display list | OAM | -| BGPLANE | fullscreen quad | fullscreen quad | VDP2 config | fullscreen quad | fullscreen quad | BG layer config | -| UI_SPRITE | 2D ortho quad | 2D GU quad | VDP2 BG plane | GPU rect packet | RDP rectangle | BG layer tile | -| MESH | VAO/VBO | GU buffers | (degrade: quads) | (degrade: tris/quads) | RSP display list | (not supported) | - -Note: N64 supports both triangles and axis-aligned rectangles natively via -RDP. PS1 supports triangles and quads (4-vertex) natively, so neither needs -the dead-vertex trick that Saturn requires. - ---- - -## Asset Pipeline: Platform-Native Formats - -### The problem - -All textures currently enter the engine as RGBA and are converted at -runtime by each platform (Dolphin retiles to 4x4 blocks; GL uploads as-is). -This wastes memory and CPU time, and is impossible for platforms where RGBA -is not a valid intermediate format at all. - -### The solution - -The asset compiler (offline, run at build time) produces platform-specific -binary bundles. A texture asset has one source (PNG or similar) but N -compiled outputs, one per target. - -### Texture formats by platform - -| Platform | Native Formats | Notes | -|---|---|---| -| Modern GL | RGBA8, RGB8, BC1-BC7 (compressed) | Upload directly, GPU handles | -| Legacy GL | RGBA8, RGB8, CI8 (palette via extension) | No compressed formats | -| Vulkan | VkFormat variants (RGBA8, BC, ASTC) | Chosen at compile time | -| PSP GU | ABGR8888, BGR5650, ABGR1555, ABGR4444, CI4, CI8 | Native swizzled format | -| Saturn VDP1/VDP2 | RGB555, CI4, CI8 (15-bit palette in CRAM) | Big-endian, packed | -| PlayStation 1 | RGB555 / CI4 / CI8 (CLUT in VRAM) | Little-endian; VRAM flat; CLUT at coord | -| Nintendo 64 | RGBA16, RGBA32, IA4-IA16, I4-I8, CI4, CI8 | 4 KB TMEM; tiles must fit in TMEM banks | -| GameCube/Wii GX | I4, I8, IA4, IA8, RGB565, RGB5A3, RGBA8, CMPR | 4x4 tiled, big-endian | -| SNES PPU | 2bpp, 4bpp, 8bpp indexed (CGRAM palette) | Tile-packed, no direct access | - -### Asset bundle structure - -The `.dsk` bundle gains a platform tag. The loader picks the right section -at runtime (or the build produces a single-platform bundle for constrained -targets like SNES/Saturn where there is no spare storage for unused data). - ---- - -## UI System (first-class) - -### Current problem - -UI elements go through the 3D pipeline: they are meshes with an orthographic -shader, rendered in the same pass as the world. This means: -- UI competes for Z-buffer depth with world geometry -- On Saturn/SNES, UI cannot use dedicated hardware planes -- Text rendering is tied to the sprite batch which is tied to the 3D pass -- No separation between "draw the world" and "draw the HUD" - -### New model - -UI is a completely separate rendering context. The world renders first, -then the UI renders on top. They share no state. - -UI coordinates are always in screen space (pixels or a logical resolution -that the platform scales to its native display size). No camera matrix, -no projection, no depth buffer involvement. - -### Platform mapping - -| Platform | UI implementation | -|---|---| -| Modern GL | Separate 2D ortho pass, screen-space quads, no depth test | -| Legacy GL | Same, using fixed-function | -| PSP GU | Separate GU display list, 2D mode | -| Saturn | VDP2 background plane(s) dedicated to UI | -| PlayStation 1 | Separate GPU packet chain, no Z; ordered after world OT | -| Nintendo 64 | RDP rectangle commands in a separate display list segment | -| GameCube/Wii | GX 2D mode or dedicated GX pass | -| SNES | Dedicated BG layer(s) for HUD tiles | - -On Saturn, the UI occupying VDP2 planes is a genuine hardware win -- the -PPU composites it for free at scanline time, costing zero VDP1 commands. -On SNES, the HUD must live in a BG layer because there is no alternative. - -### UI API (proposed) - -```c -uiBegin(); - uiDrawRect(x, y, w, h, color); - uiDrawSprite(x, y, w, h, texture, uvMin, uvMax); - uiDrawText(x, y, font, string); -uiEnd(); // platform flushes UI to hardware -``` - -The `uiBegin`/`uiEnd` block collects intents; the platform submits them -at frame end in whatever way is appropriate. - ---- - -## SNES / Mode7 - -SNES is the most constrained platform the engine will ever support and -needs its own section because it breaks assumptions that even Saturn keeps. - -### Hardware - -- **CPU**: 65816 @ ~3.58 MHz (16-bit, no FPU, no cache) -- **PPU**: Tile-based scanline renderer. VRAM holds tile graphics and - tile maps. BG layers reference tiles by index. -- **Mode7**: A single BG layer with a 2D affine matrix applied per - scanline. Used for overworld maps, road perspective (F-Zero), rotation - effects. The matrix is set via HDMA (scanline DMA) for per-scanline - variation, enabling horizon-perspective effects. -- **Sprites/OAM**: Up to 128 sprites (8x8, 16x16, 32x32, 64x64 pixels), - 4bpp indexed, up to 8 per scanline. -- **Palette**: CGRAM holds 256 entries of 15-bit RGB (512 bytes total). - BG layers use sub-palettes of 4/16/256 colors depending on bit depth. -- **VRAM**: 64 KB (tiles + tile maps) -- **WRAM**: 128 KB work RAM + usually 8 KB SRAM on cart for saves -- **No frame buffer.** The PPU renders scanlines directly. You cannot - read back what was drawn. -- **No general-purpose draw calls.** You configure registers and VRAM - before the frame and the PPU does the rest. - -### What "3D" means on SNES - -True 3D is not possible. What can be approximated: -- **Overworld map**: Mode7 with a flat texture and HDMA scroll gives a - top-down perspective with a horizon line (the classic JRPG overworld). -- **Depth illusion**: Mode7 matrix manipulation can simulate a moving - camera over flat terrain. Objects are sprites placed at screen positions - calculated by software perspective projection. -- **Sprite scaling**: Software-scaled sprites using pre-rendered frames - or the RSP-style tricks used in Super FX games (Star Fox). Super FX - is a co-processor on the cartridge -- base SNES cannot do this. -- **Basic 3D effects**: Some games use HDMA color gradient + Mode7 floor - with overlaid sprites to create a pseudo-3D look. - -The engine plan for SNES: Mode7 overworld (confirmed), sprite-based world -objects, BG layer UI. "Basic 3D effects" (pseudo-perspective with sprites) -is aspirational -- implementation complexity TBD. - -### SNES constraints on the engine - -- **No dynamic allocation.** With 128 KB WRAM, a general-purpose allocator - is risky. The engine memory system may need a static pool mode for SNES. -- **No floating point.** `float_t` must resolve to integer or fixed-point. -- **No scripting (JerryScript).** The JS engine requires far more than - 128 KB RAM. SNES scenes must be compiled C. -- **Asset data in ROM, not a .dsk bundle.** SNES loads from cartridge ROM - mapped into the address space. The asset system needs a ROM-mapped loader. -- **Tile pipeline.** Textures must be pre-converted to SNES tile format - (2bpp/4bpp/8bpp, 8x8 pixel tiles, CGRAM palette) at build time. This - is a completely different asset output from every other platform. - ---- - -## Platform Inventory - -A summary of what each platform's native rendering looks like after the -refactor, for reference when designing the intent API. - -### Modern OpenGL (duskgl) - -VAO + VBO mesh storage, GLSL shaders, FBO render targets, Z-buffer. -No fixed-function. Targets: Linux, possibly Vita (GXM is preferred). - -### Legacy OpenGL (duskgllegacy) - -Fixed-function pipeline: `glMatrixMode`, `glTexEnv`, client-side vertex -arrays. No VAO/VBO. Used for: very old desktop hardware, maybe PSP as -last resort (PSPGL is this). Targets: legacy desktop, embedded Linux. - -### Vulkan (duskvulkan) - -Explicit pipeline state objects, render passes, descriptor sets, command -buffers. Highest ceiling for performance and control. Targets: Linux -(modern), future platforms. Not immediate priority but the architecture -should not block it. - -### PSP native GU (duskpsp) - -The GE/GU is a display-list GPU. You build a command list in memory and -the GU DMA engine processes it asynchronously. Native vertex formats are -PSP-specific (ABGR byte order, swizzled textures for cache efficiency). -No PSPGL. Targets: PSP hardware and emulators. - -### Vita (duskvita) - -GXM is Sony's Vita GPU API -- closer to modern GL than GU, with explicit -shader binaries (.gxp), ring buffers, and GPU sync primitives. - -### GameCube/Wii GX (duskdolphin) - -Already a custom renderer. GX uses immediate-mode vertex submission -(`GX_Begin` / `GX_Position1x16` loops), TEV for texture compositing, and -hardware XFB double-buffering. Big-endian. Mostly kept as-is; may benefit -from being expressed in terms of render intents for consistency. - -### Saturn VDP1/VDP2 (dusksaturn) - -VDP1: command-list (32-byte structs), quad-based, affine texture mapping, -no Z-buffer (painter's algorithm). VDP2: up to 6 background planes -composited at scanline time. Big-endian dual SH-2, no FPU. Fixed-point -math required throughout. - -### PlayStation 1 (duskps1) - -MIPS R3000A @ 33.87 MHz, little-endian, no FPU. GTE (coprocessor 2) -handles fixed-point matrix math, perspective divide, and lighting. -GPU receives packets via DMA linked-list (the Ordering Table). Primitives: -triangles and quads natively (no dead-vertex needed). Texture mapping: -affine, same limitation as Saturn. No Z-buffer; depth is OT slot order. -VRAM is 1 MB flat (frame buffers + textures + CLUTs share it). SDK: -PSn00bSDK, which is CMake-native -- a direct fit for the dusk build system. - -### Nintendo 64 (duskn64) - -VR4300 @ 93.75 MHz, big-endian, real IEEE 754 FPU. Rendering is split -between the RSP (geometry: programmable MIPS SIMD, runs microcode up to -~1000 instructions in 4 KB IMEM) and the RDP (rasterization: fixed -hardware). RSP produces triangle commands from a CPU-built display list -in RDRAM. RDP features: perspective-correct texture mapping, bilinear -filtering, hardware Z-buffer. Primitives: triangles and axis-aligned rects. -TMEM is 4 KB on-chip texture cache; textures must be loaded into tiles -before drawing -- a significant memory management constraint. -SDK: libdragon (Unlicense, GCC 14, Makefile-based -- not CMake; this -requires a wrapper toolchain file for dusk's build system). - -### SNES PPU/Mode7 (dusksnes) - -Tile-based. VRAM holds tiles and tile maps. Mode7 provides affine transform -for one BG layer. Sprites via OAM. No frame buffer. All configuration is -memory-mapped registers. 65816 CPU, no FPU, extremely limited RAM. - ---- - -## Threading Model - -### Current model - -The engine uses OS threads for async asset loading (`assetXxxLoaderAsync`). -Platforms that have pthreads or an equivalent RTOS (Linux, PSP, Vita) run -worker threads that load data in the background while the game loop runs. -The main thread polls or blocks on completion. - -### The problem - -Several target platforms have no OS threading whatsoever, and others have -hardware-specific async mechanisms that are nothing like pthreads. - -### Per-platform reality - -| Platform | Threading | Async mechanism | -|---|---|---| -| Linux | pthreads | Worker threads (current) | -| Vita | SceKernelThread | Per-SDK threads | -| PSP | SceKernelThread | Per-SDK threads | -| GameCube/Wii | libogc LWP | Lightweight processes | -| Saturn | None (OS) | Slave SH-2 for fixed jobs; CD-ROM via interrupt/callback | -| PlayStation 1 | None (OS) | V-blank ISR, 7 DMA channels, CD-ROM callbacks | -| Nintendo 64 | libdragon preview only | PI DMA for cartridge; RSP for parallel compute | -| SNES | None | DMA (GPDMA/HDMA); NMI V-blank; SPC700 audio is a separate CPU | - -**Saturn slave SH-2**: The second SH-2 is not a general-purpose thread. -It runs a fixed subroutine you hand-load. The typical use is offloading -heavy per-frame computation (geometry transforms, depth sort) while the -master SH-2 handles game logic. Communication is via shared WRAM with -cache-through addresses to avoid coherency bugs. There is no scheduler -and no yield -- it runs to completion. - -**SNES DMA**: GPDMA copies blocks of data (ROM to WRAM, WRAM to VRAM) -and halts the CPU for the duration -- it is synchronous from the game's -perspective. HDMA runs per-scanline during H-blank, writing to PPU -registers without CPU involvement; this is how Mode7 perspective is -achieved. Neither is "async" in the programming sense. - -**SNES NMI**: The V-blank NMI fires at the start of every V-blank period. -This is the only safe window to write to VRAM and PPU registers. All -critical PPU updates must complete within ~1.2ms (the V-blank window). - -### Proposed model - -Introduce a compile-time threading capability flag: - -``` -DUSK_THREAD_PTHREAD -- Linux, maybe Vita -DUSK_THREAD_SCEKERNEL -- PSP, Vita SDK -DUSK_THREAD_LWP -- GameCube/Wii libogc -DUSK_THREAD_SLAVE_SH2 -- Saturn slave CPU (job dispatch only) -DUSK_THREAD_NONE -- SNES (and Saturn master thread view) -``` - -The asset loader's async path is gated on having a threading capability. -When `DUSK_THREAD_NONE` is defined, `assetXxxLoaderAsync` either does not -exist or is an alias for the synchronous version. On Saturn, the slave SH-2 -is exposed as a distinct API (`sh2JobDispatch`, `sh2JobWait`) used only for -compute-heavy work, not for I/O. - -### Asset loading without threads - -**Saturn**: CD-ROM access is initiated via SBL/CDC routines and completes -via interrupt callback. The engine's asset loading loop can poll the -callback flag in the main loop rather than blocking a thread. This is -interrupt-driven cooperative async, not preemptive. - -**SNES**: There is no loading. Assets live in ROM, mapped directly into the -65816 address space. "Loading a texture" means computing a pointer into ROM -and copying the tile data to VRAM during V-blank via GPDMA. The asset system -on SNES is essentially a VRAM/CGRAM allocator and a DMA scheduler, not a -file loader. - -### Asset system changes - -The asset pipeline needs to accommodate three loading models: - -1. **File-based** (Linux, PSP, Vita, Saturn CD): open file, read bytes, - close. Can be sync or thread-async. -2. **DMA/interrupt** (Saturn CD-ROM, GC DVD): initiate transfer, poll or - callback on completion, no thread blocked. -3. **ROM-mapped** (SNES): data is already in the address space; "loading" - is a VRAM DMA copy scheduled for V-blank, not file I/O. - -The `assetstream_t` abstraction that currently wraps file I/O needs a third -backend for ROM-mapped data, and the async path needs to support -callback-based completion as an alternative to thread-based blocking. - ---- - -## What Needs to Change - -### 1. Render intent API (new, in src/dusk/) - -Replace `mesh_t` / `shader_t` / `meshDraw()` as scene-facing APIs with -`renderqueue_t` and intent submission functions. `src/dusk/` defines the -intent types and submission API; platforms implement the flush. - -### 2. Platform renderer directories - -Move rendering implementations out of `duskgl/` as a shared layer and -into fully self-contained platform directories. `duskgl/` becomes the -*modern GL* platform only. Add `duskgllegacy/`, `duskvulkan/` as peers. - -### 3. Asset pipeline: platform-native texture formats - -The offline asset compiler must produce per-platform texture bundles in -native formats. The runtime texture loader expects pre-converted data, -not RGBA. `textureformat_t` grows to cover all platform formats but each -platform only ever sees the formats it natively supports. - -### 4. UI system (first-class, separate from 3D) - -New `src/dusk/ui/` subsystem with `uiBegin` / `uiEnd` and intent types -for rects, sprites, and text. Platforms implement the flush independently. -The 3D spritebatch is retired or scoped to world-space billboards only. - -### 5. Fixed-point / no-FPU math - -`float_t` needs a fixed-point mode. Proposed: define `fixed_t` as a -16.16 signed integer; define `DUSK_MATH_FIXED` for platforms that require -it (Saturn, SNES). Engine math utilities (`mathSin`, `mathCos`, etc.) -have fixed-point implementations selected by this flag. `float_t` on -FPU-less platforms becomes a typedef for `fixed_t`. - -### 6. Background plane abstraction (bgplane_t) - -New concept in `src/dusk/display/bgplane/`. A BG plane has a tile map or -bitmap source, scroll offsets, a palette reference, and optional affine -parameters (for Mode7-style use). On GL platforms: rendered as a -fullscreen textured quad or shader pass. On Saturn: VDP2 config. On SNES: -PPU BG layer config. - -### 7. Memory system: static pool mode - -For SNES (and possibly Saturn), the general-purpose allocator may be -unviable. A compile-time static pool mode (`DUSK_MEMORY_STATIC`) that uses -a fixed-size arena instead of dynamic allocation. All `memoryAllocate` -calls hit the pool; `memoryFree` is a no-op or a stack pop. - -### 8. Script runtime: optional - -JerryScript requires too much RAM for SNES and is marginal on Saturn. -The scripting system should be compile-time optional (`DUSK_SCRIPTING`), -not assumed present. SNES/Saturn scenes would be compiled C. - ---- - -## What to Keep - -- Platform macro abstraction pattern (`displayplatform.h`, etc.) -- works, - no reason to change. -- Directory structure convention for platform directories. -- Entity-component system -- platform-agnostic, unaffected. -- Asset loading + `.dsk` bundle concept (extended for platform formats). -- The broad subsystem layout: asset, input, display, log, network, save, - system, time. - ---- - -## Open Questions - -1. **Render intent granularity**: How much does the intent API need to - express? A MESH intent works on GL/N64 but degrades poorly on Saturn - (must split into quads) and is impossible on SNES. Should MESH be a - valid intent with a "best effort" contract, or excluded from the portable - API entirely? - -2. **Threading abstraction depth**: Should `DUSK_THREAD_SLAVE_SH2` be a - first-class concept in the engine's job system, or a Saturn-internal - implementation detail the core never sees? Same question applies to N64's - RSP as a compute co-processor. - -3. **Asset loading async contract**: When a platform has no threads, should - `assetLoadAsync` be a no-op alias for `assetLoadSync`, or return - immediately with a completion flag to poll? The polling model is more - honest but requires all call sites to handle it. - -4. **N64 build system**: libdragon uses GNU Make, not CMake. Options are: - (a) write a CMake toolchain file that wraps n64.mk, (b) maintain a - parallel Makefile just for N64, or (c) wait for upstream CMake support. - Which is acceptable long-term? - -5. **N64 RSP microcode**: Standard libdragon microcodes (Fast3D/F3DEX2) or - Tiny3D (community microcode with full T&L + skinning)? Writing custom - microcode is powerful but limited to ~1000 MIPS SIMD instructions. - This decision gates what 3D features the N64 port can support. - -6. **PSPGL fate**: Drop immediately in favor of native GU, or keep as a - fallback (`duskgllegacy`) while native GU is built? The two can coexist - during transition. - -7. **Vulkan priority**: Design the intent API with Vulkan in mind from the - start, or add it later? Vulkan's explicit pipeline state model may - conflict with how stateful platforms (Saturn, SNES) expect things to work. - -8. **Background planes on modern platforms**: Does `bgplane_t` degrade to a - fullscreen textured quad on GL/Vulkan/N64, or should modern platforms - support actual background scene rendering (3D world behind the foreground)? - -9. **PS1 ordering table depth**: The OT is a fixed-size array (e.g. 4096 - slots). Depth precision = number of slots. How deep should the engine's - default OT be, and should this be configurable per-scene? - -10. **Fixed-point strategy**: Does `float_t` transparently become `fixed_t` - on FPU-less platforms (Saturn, PS1, SNES), or do we require explicit - `fixed_t` in math-heavy paths? Transparent is easiest to port; explicit - is faster. - -11. **SNES V-blank budget**: All VRAM writes must finish within ~1.2ms. - Does the engine need a V-blank work queue with a budget checker, or is - this left to the game to manage manually? - -12. **SNES scripting**: JerryScript is out. Pure compiled C, or a lighter - scripting layer (Lua is ~100 KB -- tight but possible)? - -13. **Asset compiler**: New standalone tool, or an extension of the existing - asset pipeline? Part of the CMake build or a separate pre-build step? - ---- - -## Proposed Sequence (Draft) - -### Phase 1 -- Intent API (no behavior change) -1. Design and stabilize `renderqueue_t` and intent types -2. Refactor modern GL path to submit through render intents (same output, - new plumbing) -3. Refactor Dolphin path the same way -4. Validate no regressions on Linux + GameCube - -### Phase 2 -- UI system -5. Extract UI rendering from the 3D path into `src/dusk/ui/` -6. Implement UI flush for GL and Dolphin -7.
