Return to Trackmouse (idea)

A short BASIC program that allows you to move the cursor around your C64 screen with a joystick or trackball. A very useful program, since the cursor control keys on the Commodore 64 suck.

The program works with any trackball or joystick plugged into port 2. You can turn Trackmouse off by hitting Run/Stop-Restore and turn it back on by typing SYS49152. Also, pressing the fire button performs the same action as hitting the Return key.
