Nostalgia

Thanks for the info. Maybe I'll try to pick up a cheap NDS. Would you happen to have a link to that guide?

So I joined this forum because of this thread as this topic fascinates me, however I have no idea how to get this to work on an actual cartridge. I only play on cartridges and never emulators. I have UK Ruby, Emerald, Fire Red and Leaf Green. I also recently picked up a 3DS. Can anyone help a complete newbie out on this matter?
