Complete noob to the 3DS rom scene, but I picked up some stuff but I can't find any clear guides on it. I want to run Smash Bros online, and I can get a private header and a powersave dongle (but which one? I live in USA, btw), but I don't know how to put in my header for the game. So if someone could inform me what to buy and how to actually use the retail cards and the software, that'd be great. Anything else I need to know to play online without getting banned? I can't dump my own ROMS because I don't have a Gateway/Gateway-compatible device. So can I get a random .3ds or .3dz (and what's the difference?) and smack my headers into it? Edit: I mean, I'm so noobish, I need a step-by-step from Beginning to End. Edit again: I can get most headers from friends so we can play together. Are there any risks from that? Or not so much.
