Play Action Replay (Program) Online

Action Replay wasn't a game—it was the cheat code holy grail for the Sega Genesis. You plugged this little cartridge in, typed in some weird numbers, and suddenly you're cruising through Ghouls 'n Ghosts with infinite continues like some kind of gaming demigod. No more scribbling codes from magazines or hoping your friend's cousin's neighbor had the right button combo.

I remember the first time I used it on Sonic 2—instantly turned into Super Sonic right from Green Hill Zone. Felt like cheating (because it was), but also like discovering some hidden developer backdoor. The interface was this clunky grid of numbers, but once you got the hang of it, you could tweak anything. Ever wanted to make Streets of Rage enemies move in slow motion? Yeah, that was an option.

These days, mods and trainers are everywhere, but back then, Action Replay was basically black magic. Half the fun was breaking games in ways the codes weren't even meant for. Sometimes it'd glitch out spectacularly, but when it worked? Pure 16-bit power trip.
