Tested and working Bare Metal C64 running on a Raspberry Pi Zero with keyboard.

Includes 32GB SD card containing some software.

With a boot time of just over 4 seconds, this is one of the fastest (and certainly one of the most portable) ways to emulate the classic Commodore 64.
You can connect joysticks to the 2 DB9 joystick ports, and output to modern TVs or monitors via the mini HDMI port (joysticks and cables not included).
Access the full menu of functions with the C= and F7 key on the keyboard. From there, load programs from tape, disk, or cart files on the SD card. Some will be included to get you started, but there is plenty of space for you to add more.
When you're done, simply unplug the power. No shutdown procedures required!NOTE: Please ask questions before purchasing. This is a homebuilt product for tinkering and can't be expected to function as a retail product. It will require you to investigate and learn more about it as you go. It is therefore sold as-is, with no returns.
Does not include joysticks, monitor, or power cable. You will need a micro USB cable to power it, and a mini HDMI cable for display.
