The programs

Video

Plays a short video of Doom gameplay (64×48 pixels, 4 colors, 10 fps, no audio).

Hello World

Prints Hello, World!.

Transgender flag

Shows the transgender flag. Note: this program is heavily optimized for size; it does not represent good programming practice. The actual size is 95 bytes (including interrupt vectors and CHR data).

The program in hexadecimal:
