A Mario Maker-style level editor for Sega's Master System classic. Pick any of the game's 17 settings, paint with its 256 raw blocks, drop any enemy anywhere, script janken bosses with up to 15 rock-paper-scissors throws, add vehicles, bonus zones and time limits. Bring your own ROM.

Under the editor, the whole game was translated from the cartridge's Z80 code to C by a recompiler I wrote in Python, then rewritten by hand into readable C, routine by routine. It compiles to WebAssembly for the editor and to a native SDL2 binary.

Faithfulness is proven three ways: every Z80 instruction against a reference emulator, the full machine state compared frame by frame with the real ROM, and each rewritten function running side by side with its generated twin during real play.

A text-based life simulator, written in French. Every year you tap "+1 year" and life answers. Short choices, long consequences: a prenup signed at 31 that wakes up at the divorce, a path forced on your daughter that comes back at a family dinner.

Start a company and take it public, run for mayor and end up a minister, build a property portfolio on credit, raise a family, grow old for real with pensions and check-ups. Your best life becomes a ghost that every new game races against, and a dynasty carries on through your heirs.

The engine is plain JavaScript, shared by the web version and a fully native Expo app with no WebView. Headless simulators play hundreds of lives to balance it, and new content ships over the air without an App Store review.

The C4 pulse quickens with the real beep timing, the explosion flashes through the room with a fireball and dying embers, round wins blink red or blue for the winning side, and a gold sweep crosses your lights when you're the round MVP.

It reads Valve's official Game State Integration, so nothing is injected into the game and the config installs itself. Effects stream to the bulbs at 50 frames per second over the Hue Entertainment API, then every light returns to the exact state it was in.

Version 2 adds a true ambilight: a tiny Rust sidecar grabs the screen through DXGI, lets the GPU shrink each frame to a small grid, and maps its zones to where your lights stand in the room.
