🕶️ A diagonal downward view of Jack and Daxter aboard a flying motorcycle, flying over a village with various passers-by idle in their daily occupations.

📚️ Jak and Daxter series is a PlayStation 2 action-platformer and adventure trilogy published between 2001 and 2004 (Naughty Dog studio) following the eponymous protagonists. Falling into a vat of Dark Eco (the antithesis of White Eco, and the 4th - malignant - variation of this form of energy), Daxter is transformed into an otter. Discovering a time machine, Jak (aka Mar) and Daxter embark on an adventure to restore his human form... OpenGOAL is a reverse-engineering of the game, followed by the writing of a GOAL compiler (the game is written in GOAL, a derivative of Lisp) to produce a libre, multi-platform (Windows & Linux), compatible and modern engine.

🕶️ A view of Goverlay's interface (superb, on a dark theme) showing on the left the vertical MangoHud settings tab (the Vulkan and OpenGL overlay for monitoring game-related system parameters), while the main part shows 5 tabs (Presets, Visual, Performance, Metrics, Extras), with the “Preset” tab selected. On the latter, 1 “Layouts” area with 5 buttons (Full, Basic, Basic Horizontal, FPS only, Custom) for selecting the physical aspect of the overlay, and 1 “Color Theme” area (Mangohud stock, Goverlay, Simple White, Old afterburner) for selecting a color theme. Further down, a “Blacklisted Apps” button, a “Global Enable” selector, a sandwich button and a green “Save” button.

📚️ MangoHud is a libre tool adding a graphical overlay (OpenGL and Vulkan support) allowing to monitor the system load (CPU/GPU load, framerate, temperatures, memory usage, and more). 
GOverlay is another complementary libre project delivering an interface to set up MangoHud, to choose what information will be displayed.
