RETRO TRACER FOR CARTRIDGES

Got an old game cartridge and ever wondered what's going on inside it? Photograph its board, front and back, and trace it — follow the copper with your eyes and a cheap multimeter, and the tool turns what you prove into a real map. Red dots turn green as the wires earn their place. No experience needed, nothing to install: it all happens right here in your browser.

SHOW ME HOW — WALK ME THROUGH MY FIRST BOARD

never traced anything before? take the walk-through — it opens a real board and lights up one thing at a time. Or scroll down and play with an example.

ADD YOUR BOARD

Two photos and you're tracing. Your photos and your map stay in this browser — nothing is uploaded anywhere.

Both faces are needed before the mapping starts — a board can't be traced honestly from one side, because half its copper lives on the other.

PLAY WITH AN EXAMPLE

The same board, twice — one finished so you can read how it was done, one blank so you can do it yourself. Whatever you do to them stays on your copy.

A whole board already traced: 364 points, every wire proven. Read it, poke it, even wreck your copy — one tap brings the original back.
OPENS FULLY TRACED

Where the walk-through starts. Two chips, two glob tops, and no loose parts at all — so it also teaches you when to skip a step.
WAITING FOR ITS FIRST MARK
Everything you trace lives in this browser and can be exported as a file whenever you like. Tracing on a tablet? Export after a good session — browsers can be forgetful with things they think you've abandoned.
