A friend recently bought a Europe region console with Luma already and some games installed. I'm not sure which region the games were from but select games cannot play with my console. Can't even see the other 3ds... So far, we've tested Mario kart, Mario party island tour, and new super mario Brothers 2. Tekken won't even load at all. Gives out an error. I'm wondering if it's a problem of the Europe console + us game vs us console + us game or is it a Europe console + Europe game vs us console + us game. My console is all the same region with all games and I'm not sure if his is different but that's all the difference I can see. Both consoles on Luma.
