The thing about the Saturn is that it has built in battery powered memory. The problem of that of course , is that when the battery dies all the game saves and scores are gone. The solution is this memory cart. There's more memory than you;ll ever need and it's very reliable. The saturn states that it has 500 blocks. Small games are no problem until there's big racing game files like Sega Rally or Daytona USA. The memory cart has 8000 blocks of memory to work with and that's plenty for everything. Even collectors will have space for all those games.
