Great Object!
One of the best items for a Sega Saturn! Its only complaint is the way you need to use: sometimes you need to reinsert it into the port more than once, but when console detects it you'll enjoy hours and hours of imports. Plus, the memory system works fine. Recommended!


  • Action Replay cheat function
  • Auto switch 1M and 4M Expension RAM card built-in (for Capcom Fighting games, Metal Slug and others)
  • 4M memory card function
  • allows playback of import games
  • compatible with all Saturn versions


This is the ultimate enhancement for your beloved Saturn console. It features all in one: a cheat cartridge function (compatible with Action Replay codes), an auto switch 1M and 4M Expansion RAM card (to play games such as the Capcom fighting games, Metal Slug, King of Fighters and more), a 4M memory card as well as an import adapter to play foreign games on any Saturn console.

Poor Quality Control
The unit I was sent worked fine as an AR device but the expansion RAM didn't work at all. Considering I bought it specifically to play RAM expansion games, this is a complete product fail for me. I have an older "Action Replay 4M Auto Plus" - the one with the serial port on top which I purchased back in the 90's, and it works flawlessly on all of my Saturn consoles - this rules out problems with the console and the game. In searching around the Internet it seems like this particular defect is a regular occurrence with this version of the cartridge. Unless you live in Hong Kong I would recommend against buying it from Play-Asia because although they've very polite, the return process is not consumer friendly. I'm not trying to focus on the service I received, but it's absolutely relevant to a purchasing decision to know the return process - especially if the item is known to have a high rate of defects. It took three weeks of back and forth before they would approve an RMA and even though I've shown them video demonstrating the defect they required me to pre-pay return postage and only agreed to reimburse me if they decided that the product was defective when it arrives back in Hong Kong.

Great, but not completely flawless.
First of all, it should be called "4 in 1" simply because four are the advantages of this cartridge, not just three. I will explain the "risk" of these cartridges later on.

It works wonderfully well, making your Saturn able to play games from any region, apply and edit cheats, store your saved games (only from the cartridge menu) and providing the extra RAM some games need to work.
And is in this last point where the risk comes, as the 1MB/4MB is not properly recognized by the games in some of these cartridges. I don't know why or how often this happens, but you have a probability of getting a cartridge that will produce graphic glitches and freeze your game on the 1MB/4MB Capcom/SNK games.

Apart from that, it works flawlessly and is the best accessory you can have plugged into your Saturn.
