MKI A500 cartridge

The Amiga was one of the first systems to have a Action Replay released on it. All versions featured a slow mo button which would slow down gameplay. They also contain on and off buttons and a freeze button. The freeze button opens up the menu which allows access to the Action Replays features. All versions of the action replay allowed users to alter RAM in real time and cheat on games. They could also view sprites and allow users to listen to music. It was also possible to make back-ups of games. As later versions of the Action Replay were introduced the number of features were also increased.

All Amiga Action Replays were produced in the early 90's by Datel.
