Hi everyone ! Just got a US cardridge for my European 3DS and .... you know the problem. The game even does not show up..... I didn´t know that, just expected this device to accept anything. Might there be some hardware hack to free the cardridge ? I mean, something like soldering two contacts on the board or connecting through a graphit pen ? Or maybe you just have to remove some part ? Or can you say this is absolutely impossible for sure ? Does anyone know how this region lock is working technically ? THanks !
