TinyCircuits Thumby

The TinyCircuits Thumby — a tiny keychain game console — emulated down to the chip: a real Raspberry Pi RP2040 (dual ARM Cortex-M0+) on Uri Shaked's rp2040js, booting the official MicroPython firmware with the open-source Thumby API and a real game loaded from a littlefs flash filesystem. The 72x40 1-bit OLED is rendered from the SSD1306 command/data stream the firmware clocks over hardware SPI; the d-pad and A/B buttons drive the real GPIO pins; the piezo buzzer (PWM) is synthesised to the Sound button. Use the arrow keys for the d-pad and Z / X for A / B (or the on-screen pad). Press Sound to unmute. Pick a game from the menu. Open the debugger to single-step the Cortex-M0+, read/write r0-r15 / xPSR, disassemble the XIP flash and boot ROM, and set breakpoints and write-watchpoints over the real RP2040 memory map. Click the panel first so it captures the keyboard.
