booyeah!
i have two us saturns and this little bad boy lets me play all of the japanese goodness flawlessly. i have used for Xmen Vs Street Fighter, Marvel vs Street Fighter, Vampire Savior and Dead or Alive. i had to reseat it once and not push it in all the way and its worked like a charm! get it now!

Very good!
But this cartridge does not work with all the games... for PZ Saga you need to remove it... anyway, it's good.

Essential addition for retro gamers!
I recently purchased a Saturn, but some of the best games for the system are imports! This device remedies the problems associated with picking up a system these days (low internal memory, region lock-out). If you have a Saturn, you need this device.

Best thing for Sega Saturns
If you're very intested in Importing for the Saturn, or don't want to go around your city looking for the certain type of battery, this little gizmo is for you.

It not only acts as a Cheating device, but can handle any save you need done and allows any game from Japan. Highly reccommened.

Excellent!
The one and only "must have" cartrigde for the Saturn. All features/functions works great here. Highly recommended. :-)
