Ace Combat 04: Shattered Skies
Onaga00/ProjectStonehenge
A native x86-64 PC port of Ace Combat 04: Shattered Skies, based on the North American release (NTSC-U, SLUS-20152). It is built from a decompilation of the PS2 executable: the game code has been translated function by function into C++ (with AI assistance) and runs natively; the README states it is neither an emulator nor a static recompilation. All assets, including the executable’s own data tables, are loaded at run time from your disc image. It offers an unlocked frame rate (up to 360 FPS, with game logic at 59.94 Hz), internal resolution from 1x to 8x, FXAA and SMAA, FSR 1 upscaled cutscenes, PCSX2-compatible saves (still in beta), and a built-in debugger; code unused in the final game has been ported too. VS mode and Linux are listed as pending. Version v0.9.6-beta is from October 27. The README declares extensive use of Anthropic’s generative AI under human supervision.

PresidentRaptor/Ace-Combat-04-PC-Port
A work-in-progress native Windows port of Ace Combat 04: Shattered Skies (USA, SLUS-20152), made by static recompilation: the original executable’s main CPU functions are translated ahead of time to C and compiled into ac4.exe, and a shared runtime stands in for the console (GS graphics through Vulkan, vector units, audio, movies, memory cards, and input). The recompiler and runtime come from sal063’s Ace Combat 5 recompilation, to which this project adds the AC4 configuration, its own sound services, and the rendering, widescreen, and Windows fixes. According to the README, mission 01 was completed in live play, and boot, movies, briefings, aircraft and weapon selection, and flight were checked at native and 6x resolution; later missions still need full playthroughs. It offers up to 8x internal resolution, FXAA, sharpening, optional texture packs, and Lua or native mods. Version v2.2.3-beta is from October 21. 31 of its last 64 commits list Claude as a co-author.
You needYour own Ace Combat 04: Shattered Skies image for PS2, unmodified US release (SLUS-20152), and the disc data. The Windows installer asks for the ISO, verifies the game executable, copies the ISO, and creates the local memory image; it needs about 4 GB free, .NET Framework 4.8, and a Vulkan 1.3 graphics card.
