Edition of 30

Seoul, 2026.08.

firmware 1.4.6 — a critical input fix is out. update your TR-2 here →

A game console the size of a keyring. A single board carries the display, four keys and the microcontroller, with nothing around them — the board itself is the object.

Ten pixel games are built in. The board takes new firmware over usb-c, so later games arrive on the same board.

Drawing of the TR-2 board: display, four keys, usb-c and the key hole
The drawing from the packaging. Key hole is 2.4mm.
Left alone for thirty seconds, the display does this — the same idle screen the board runs, at its own 128 × 32.

how to play

  1. Plug in usb-c. It starts on its own — there is no power switch.
  2. Pick a game. The display tells you what each key does.
  3. Hold A+B for a second to come back to the menu. PONG and REACT use A and B to play, so there you hold all four.

Leave the menu alone for thirty seconds and a screensaver takes over, so the display does not burn in.

software

More games arrive with later firmware. Updating is one file dragged onto a drive — nothing to install.
