Hello Atari 5200 (demo)

demo Open · freely redistributable

A self-authored, public-domain Atari 5200 cartridge (32K). It installs its own ANTIC mode-2 display list, prints "HELLO ATARI 5200" using the BIOS character set, and reads controller-0's analog stick (POKEY POT0/POT1) into the background and text colours every frame — so moving the on-screen d-pad visibly changes the screen. A tight, fully-visible loop that is an ideal debugger target: set a breakpoint on the read loop, single-step the 6502, or watchpoint the colour register.
