From b2190e8cb16b13d84bb6fd063531109d7aeaadb0 Mon Sep 17 00:00:00 2001 From: KaiserGranatapfel Date: Tue, 10 Feb 2026 20:53:38 +0200 Subject: [PATCH] feat: implement full runtime, GX graphics engine, audio/video systems, and Lua-driven UI Replace all SDK logging stubs with functional implementations so recompiled GameCube binaries can actually boot and run. OS/SDK Foundation: - Arena heap allocator (lo/hi cursors in GC address space) - Timebase timer (40.5 MHz), interrupt system (32 slots) - OSInit, OSReport, OSFatal and SDK dispatch routing GX Graphics Engine: - Full GX state machine (21 vertex attrs, 16 TEV stages, matrices, blend/Z/cull/scissor/viewport, lighting channels) - Vertex accumulator with GXBegin/GXEnd and auto-flush draw lists - Dynamic WGSL fragment shader generation from TEV configuration - wgpu render pipeline cache keyed on GX state hash - EFB at native 640x480 with depth buffer and upscaling Video Interface: - NTSC/PAL mode support, VBlank timing, retrace callbacks Audio System: - Audio Interface with DMA, Nintendo DSP-ADPCM decoder (64 voices) - Stereo mixer with resampling, cpal output thread Lua-Driven UI: - Expanded widget system (14 types with callbacks, styles, children) - 7 Lua screen definitions (main menu, FPS, graphics, audio, controller config, game settings) - Callback registry with thread-safe string-based function lookup - Full Iced rendering of all Lua widget types Game Boot Loop: - winit 0.30 ApplicationHandler with window creation and ESC menu toggle - SDK init sequence, CPU context setup, DOL section loading Bug Fixes: - CMPR/DXT1 texture decoder with correct 8x8 macro-tile Z-order layout - All 8 texture formats now use correct GC tile-based iteration - LRU texture cache with proper VecDeque access-order tracking - Memory mapper: removed ARAM overlap, added uncached mirror and HW regs - DMA execute_transfer with actual RAM/ARAM byte copying - Controller profile round-trip serialization with typed structs - Resolved all clippy warnings across entire workspace (70+) - Bumped MSRV to 1.80 (LazyLock usage) --- .clippy.toml | 3 +- game/Cargo.toml | 6 +- game/src/main.rs | 187 +- gcrecomp-cli/src/commands.rs | 101 +- gcrecomp-cli/src/output.rs | 30 +- gcrecomp-core/src/lib.rs | 1 -
