Classic Game Room reviews the ACTION REPLAY 4M PLUS card for Sega Saturn, also known as a 4 in 1 card or Action Replay cartridge. It gives players the ability to play import games on a Sega Saturn from a different region, for instance CGR can play Japanese (Japan only) releases on an American Sega Saturn with this Action Replay card that easily defies region encoding without problem. The Action Replay card also acts as a memory expander to save Sega Saturn game files and allow gameplay of Capcom games needing 4MB memory like X-Men vs. Street Fighter. Action Replay card comes with cheat codes for various games to jump ahead levels or become invincible, additional codes available.
