Play Pro Action Replay (program) Online

Pro Action Replay was a hardware cartridge released for the Sega Genesis, also known as the Mega Drive. It wasn't a game, but a device that let you modify the games you already owned. You plugged it into the console's cartridge slot, then plugged your game cartridge into the top of it. This was a common type of accessory during the 16-bit era, giving players a way to alter their gaming experience directly.

You don't control a character; you interact with a menu system to input codes. The main objective is to activate cheats, like infinite lives, level skipping, or invincibility. Signature mechanics include entering specific alphanumeric codes for different effects and using a built-in memory search function to find and change values yourself, such as your character's health. The pacing is entirely up to you, as you decide when and how to apply modifications. It feels like having a direct line into the game's inner workings, letting you bend the rules to your will.
