Boots straight to Battlezone attract mode -- the wireframe tank battle demo with the mountains and volcano on the horizon. Press 5 (or C) to insert a coin and 1 to start. It is a dual-stick tank: W / S drive the left track forward / back, Up / Down drive the right track -- both forward to move, opposite to turn -- and Space fires. Click the screen first so it captures the keyboard. Open the debugger to single-step the 6502, read and write registers and memory, watch the AVG vector RAM display list, and set breakpoints and write watchpoints.
