Several years ago I bought a used Saturn at the Record Exchange here is Saint Louis. They had no games available, but I got it anyway for $20.
It's a US version, model # MK-80000A
I really would like to begin accumulating some games, as I own exactly ZERO Saturn games currently - BUT I am aware that the best games are JP region.
I just ordered an Action Replay 4meg cart from Racketboy, but I'm wondering if I need to track down a modchip as well...
Do I need one? Will I be able to play JP region games without a modchip?
Is a modchip only really needed for playing "backups"?
I'd love to get my Saturn on, as it's the only console that I've never played

I'd love to get my hands on Cotton, Souky, Batsugun, etc...
Anybody got some tips for an owner of a US Saturn?
Thanks!
