This is me demonstrating the steps needed to run the red Gateway cart on your Nintendo 3DS. Please be aware that this is only possible on firmwares between 4.0 and 4.5, do not update your 3DS if you wish for this to work.
I am in no way affiliated with Gateway, this video is meant for my review over at DS-Scene.net,http://www.ds-scene.net/?s=viewtopic&...
