Developer: Exus Corporation

Exus Corporation made Atari 2600 exercise cartridges that you play with your feet. Both of its games need the Foot Craz Activity Pad, a floor mat with coloured dots that takes the place of the joystick. In Video Jogger (1983) you run in place to move a little runner around a track, and in Video Reflex you stamp on the right dot to squash bugs while sparing the butterflies. AtariAge rates both cartridges as extremely rare.
The emulator has no Foot Craz pad, so read the note on each game page before you start one below in your browser.
