I thought I'd have a much quicker and better answer than on Gamefaqs
Well, the games is obviously not working in my NA Snes, but I was at least expecting a lock-out screen, when I boot the game it's like the TV is receiving no signal, instead of the screen going black, it stays blue, but I guess it's normal? Either the lock-out chip makes the game refuse to boot or it doesn't show the lock-out screen because the 60hz mode isn't compatible with my TV (Or my composite switch box?).
So, after doing the 50/60hz switch mod everything should work perfectly?
Also, while browsing I've heard that Terranigma has "2 extra chip", I'm not sure, they mean the lock-out chip and whatever add-on chip there's inside the cart or that the cart has those two "extra connectors" on the bottom, mine only had the middle one. I tried googling and I can't find any pic.
Thanks for the answers in advance, I just bought this for 95$ so I'm a bit nervous about paying that much for something that won't work right away, that's why there's some weird questions.
