Sweet! That's what I ended up doing too! My brother had a 9.4 OLD3DS forever because we doing have great internet. My original plan being to purchase a 2DS with really low firmware from Walmart, then if I bricked it return it as a safety net... lol but sadly that's not how it worked out. I ended up buying a second hand 3DS XL in perfect condition, barely used for $55 and traded by brother for his OLD3DS with a broken R button. Happy as a clam!
I have Skype, though I can barely get online atm, I might be delayed with replying to anything because I haven't received them or they're taking forever to send... I followed this tutorial:
http://hacked3ds.blogspot.ca/2016/01/how-to-enable-homebrew-to-your-3ds-and.html starting with Homebrew installation > Downgrading to 9.2 > installing EmuNAND > installing CFW > Unlinking SysNAND from EmuNAND > Installing BigBlueMenu through Health & Safety because NASA didn't work! Then PROFIT! This will take a few hours, you'll be following any steps with for the Old3DS, not the New3DS. I can help clarify any unclear or confusing steps in this set up process. And while I didn't have the issue, apparently some of this stuff will crash and you'll have to repeat steps multiple times before it works... Also, VERY IMPORTANT. This has a chance of bricking your 3DS. Be sure to follow every step perfectly, and double check your files before confirming anything or moving onto the next step. If all goes well you'll have this done in a few hours.
My Skype would be Starmytes xD
edit: also, search your house for a large SD card. You'll definitely want it, if not need it later! I'm using 16GB, but some people use 32GB.
