There is a way in which ghosts are able to be sent around using only the 3DS Homebrew Channel. If you go onto the homebrew "Save Manager" app and scroll along to MK7, you are able to backup your data, meaning that you can import that save whenever you want. This means corruptions won't hurt as much as you'd only lose the ghosts/VR you gained since the last time you backed up.

When you put the SD card into the computer and look inside it, there is a "replay" folder and in it there are replay files numbered 00-31 like this http://prntscr.com/8h1fo4 These files are where your own ghosts are saved. I can literally just send one of these files to someone on skype and then they can delete the file they have with that number and then replace it with the one I sent them. Then they simply go onto homebrew, go to the "Save Manager" app, backup and then import before going on MK7. The only problem is that people who receive ghosts won't be able to do a timescroll for example since the ghost would be set as their pr instead of their actual pr. I have also managed to send two people my stats (VR, coins, wins, losses, streetpasses) using this method by replacing "system" files.

I just wanted to let you guys know what you think about this and whether or not it should be allowed on the PP because after all, Homebrew isn't made by Nintendo haha

I'd be all for it personally, but I have no clue how to get homebrew on 3DS...

Using the homebrew channel, is there any way to control what ghosts you get?

@Will, there might be a way, but it isn't so straight forward. I'll need to send them one at a time to my other MK7.
@Ray, I've been working on EC2 Mario on skype about that. He says that it's possible

I can't see a way of getting it to save as a spotpass or of being able to edit it to whatever time, cuz then there will be no proper ghost.

I got the Save Manager app working (with TubeHax) and checked the ghost data in a hex editor. The way the game stores inputs is very similar to MKW. The data is in pairs where the first number is the button being pressed and the second number is the number of frames that it's held.

There are 2 sections, one for button data and the other for directional input. MKW had a 3rd section for wheelies/tricks. Input data starts at offset C4 and the bytes from C0-C3 tell how big each section is.

Section 1 - Buttons
00 = No button held
08 = A
28 = AR
18 = AL
38 = ARL
There are more but I haven't checked them yet, these are the main ones for TTs.

Example: 08 20, 28 12, 08 A5 = hold A for 32 frames, hold A+R for 18 frames, hold A for 165 frames

Section 2 - Directions
1st digit: Left & Right
0 = Full Left, 7 = Neutral, E = Full Right

2nd digit: Up & Down
0 = Full Down , 7 = Neutral, E = Full Up

77 = neutral
E7 = right
07 = left
7E = up
70 = down

There are combinations for diagonal inputs, example:
8C = slightly right, mostly up
CA = mostly right, somewhat up
19 = almost full left, slightly up

Example:
77 80, B7 01, E7 21 = neutral for 128 frames, halfway right for 1 frame, full right for 33 frames.

As for the other data in the ghost, I couldn't find where/how the time is stored. I don't see the lap splits either. The Mii Data is there and I assume the kart combination data as well.

Here's what I got for the track list. To get this I sorted each ghost by the number of frames in the input data then compared that to my sorted timesheet.
Code:

replay00.dat - Mario Circuit
replay01.dat - Rock Rock Mountain
replay02.dat - Cheep Cheep Lagoon
replay03.dat - Daisy Hills
replay04.dat - Toad Circuit
replay05.dat - Shy Guy Bazaar
replay06.dat - Neo Bowser City
replay07.dat - DK Jungle

Alright Darren, and Cole, you're absolutely amazing. Thanks so much for the track list. The frame things  are beyond me lol. Will, I am seriously a noob when it comes to this kind of stuff actually. I was just messing about a bit and managed to send some ghosts and my stats.

Idk for sure yet but If you haven't played a track and you import someone else's time you are likely to get corrupted data.

This happened to me so I don't know if that was all because of the missing time  but that was the only noticeable difference I saw when doing the same data transfer.

Are these all of your own personal records, Ray?

Wow, nice! I can't wait for all those noobs trying to steal your times on Miiverse  

Updated my mediafire with my new AF WR This goes without saying ofc, but I'll update every time I get a new PR.
