I am sorry, but I need to ask this and this seems like best place to do that. What would happen if for example: I have PAL 3DS I have PAL and NTSC game. I put PAL game inside and click start button to start game. Right at the Nintendo 3DS boot game screen, I swap game with NTSC one What would happen with 3DS? Because I know that similar was done with GameCube discs for Wii before Nintendo blocked it with update so you couldnt swap discs. Also I remember that one Pokemon game for DSi was region free. About 3DS region locking, can a developer choose to make game Region Free (like 360 developers for example), or all games will always be locked due to 3DS software???
