Current release: v2.34 (25 October 2026). For install and update details, use the release notes for the PKG you actually installed.

VCFG (vibe coded frame generator): optical-flow frame generation for games on PS4 consoles running the GoldHEN homebrew enabler, as a GoldHEN plugin. The plugin hooks the game's frame submission, builds a motion field between the previous and the current game frame on the GPU, synthesises an in-between image and presents it before the real frame: a 30 fps game is shown at 60 Hz.

Status: experimental. Verified on hardware (base console, GoldHEN): CUSA07439 (new engine), CUSA08519, CUSA00411 and CUSA00207 (classic engine): 30 → 60, in-game menu, FPS counter, anti-aliasing and sharpening. Any other installed game can be switched on in the app as EXPERIMENTAL (classic engine, may not work or may crash). See docs/COMPATIBILITY.md. Use at your own risk.

Independent hobby project. Not affiliated with, endorsed or sponsored by Sony Interactive Entertainment or any game publisher. "PS4" is a trademark of its owner and is used here only to say which hardware the code runs on. Games are referred to by their title IDs. No game code or assets are included.

1. Observe. For the first ~600 flips the plugin only watches: game buffers, pixel format, free DirectMemory.
2. Decide. It allocates its GPU slab, one 1280×720 generated surface and work buffers (≈5 MiB) at the top of the highest free DirectMemory range, registers the surface with VideoOut right after the game's buffers, and checks every frame (flip tail form, buffer sizes, compute-register state). Any mismatch → that frame is shown natively.
3. Generate. GPU passes appended to the game's own flip submit: luma pyramids → hierarchical motion search (me3/me2/me1) → filtering → phase → warp to 720p → optional post (RCAS sharpening / AA) → flip the generated image, then flip the real frame with the same flip argument.

Details: docs/ARCHITECTURE.md. Measured hardware facts: docs/FINDINGS.md.

Requirements: Windows PowerShell, Git Bash, OpenOrbis toolchain, GoldHEN Plugins SDK, LLVM (clang, ld.lld), Python 3 (Pillow for overlay/bake_fonts.py), an LLVM llc with the AMDGPU target for shaders.

The new engine keeps generated shader arrays in plugin/source/*.h; after changing IR in plugin/shaders, regenerate the arrays (plugin/build_shader.py) and replace only that shader's block. The classic engine regenerates classic/source/shaders.h on every build.

1. Download VCFG_vX.pkg from Releases and install it with the GoldHEN Package Installer (e.g. from /data/pkg).
2. Enable GoldHEN → Settings → Plugins. Start VCFG from the home screen. On start it copies the plugins to /data/GoldHEN/plugins/, backs up plugins.ini and maps eligible games (your other plugins are kept).
3. Pick a game (cross toggles FG, triangle opens its settings, square launches it). Other games appear as EXPERIMENTAL and are off until you switch them on.
4. Start the game, wait ~20 s, hold L3+R3 for 3 s for the in-game menu (the buttons can be changed in the app: OVERLAY tab, "Menu hotkey"; takes effect at the next game start).

Disable / clean reset (v2.34): in 04 PLUGIN, Square (TURN OFF) and R2 twice (WIPE ALL) both remove VCFG plugin files, VCFG plugins.ini entries/backups, and VCFG settings, adaptation and profiles. They keep logs in /data/bb_probe/ and leave third-party plugins alone. A red VCFG IS TURNED OFF banner remains until you press Cross (INSTALL) in 04 PLUGIN. Fully restart the game after changing plugin state. Save a report before cleaning if you need a single file to share.

python -I tools/console.py set CUSA07439 build/vcfg/vcfg.prx
python -I tools/console.py logs

In the app: tab 04 PLUGIN → triangle (debug log on) → start the game and reproduce → back in the app, circle (save report). Attach vcfg_report.txt (USB stick, or /data/vcfg_report.txt over FTP) to an issue. The report holds the app version, plugins.ini, firmware and game versions, settings, plugin files, an automatic summary per game and the plugin logs of the last two game starts. A small flight recorder (/data/bb_probe/trace-<TITLE>.txt: first and last 80 log lines of each game start) is always on, so even a report saved with the debug log off shows where a game start stopped.

The most useful contribution right now is data: run the discovery plugin in your games and send the reports. See docs/CONTRIBUTING.md, docs/ROADMAP.md and docs/NEXT_STEPS.md.

• Never text-replace inside shaders.h / warp720.h / post_cb.h: regenerate from IR. A global rename once corrupted 75 machine words and silently broke motion search.
• Never overwrite a PRX a game may have loaded; always a new file name. No hot unload.
• Never free memory or unregister surfaces before GPU, command and scanout retirement are all proven.
