The famous Bad Apple shadow art animation demo running on the NABU's TMS9918 video chip, synchronized with chiptune audio.

BADAPPLE.COM program is located on the A: drive in user area 1. To run this, look in the Internet Adapter or Headless menu and select Cloud CPM. After CPM loads and you are presented with a A:0> prompt, type the drive (A:), and then type the user area (user 1). If you type DIR, look for the COM file (BADAPPLE.COM). Enter that filename at the prompt to execute the Bad Apple.

But can it run Bad Apple? Since the mid-2010s, the Bad Apple demo has tested the capabilities of computing devices. The demo has been created to run on anything from text editors to the NABU PC.
