Great! Thanks for sharing your solution, now anyone with the same problem can follow your guide.

To be fair it wasn't really an issue, more of a stupid question. I was wondering why I didn't see the sparkles on my Mii, but later realized it showed up on other peoples devices anyways, and I was content with that.

Look:
MiiID is a 4-byte number
MiiID offset starts at byte = 92 x (MiiOrder - 1) + 20

So, let's find out where your 11th Mii is in the file:
92 * (11 - 1) + 20
so
92 * 10 + 20
so
920 + 20
so
940
now convert this to hexadecimal
0x3AC

You 11th Mii's data starts at offset 0x3AC.

BTW I tried making my main Mii have gold pants and it only made the Friends app freeze so don't do it.

I've made the primary Mii on two of my three 3DSes "special" and able to view my friends list without it crashing.

Unless by "friends app" you mean Mii Maker, in which case yes, it will crash if you try to edit your newly gold pants'd Mii. This is noted a few posts above yours, as the poster suggests keep a backup if you want to be able to edit your Mii in the future.

Before dumping your CFL_DB.dat for editing I do the following; go into Mii Plaza and change the Mii you're using from your personal Mii to another, then open Mii Maker and disable sharing/copying on your personal Mii, then dump your extdata.

After making your edits and recalculating the checksum, restore the newly modified CFL_DB.dat and reboot your system. Open Mii Plaza and set the Mii you're using back to your personal one.

Done. Enjoy the perks of playing the plaza games with a special Mii.

Well I don't remember seeing an option for changing my main Mii.

You can use a Gateway as well. You can find a pre-compiled .3DS around here somewhere.

However you need one or the other, either Ninjhax or a Gateway.

so i need the .3ds version cool but where ? jaja

How do I find out, what Bit to change? I read the guide from conanac, but can't really follow him...

Can someone give me a hint how to make this?

All I could do was a color change, somehow or deleting the Mii...

conanac said:
Just FYI, if somehow you want to use old Mii then the MiiID may not start with 94 (i.e. you cannot find this number in your CFL_DB.dat file).

Here is a simple tutorial how to find the location of your MiiID of interest along with the disabling sharing bit location as well (I use the same two Miis information from the first posting, see the first hex-editor picture):

MiiID is a 4-byte number
MiiID offset start at byte = 92 x (MiiOrder - 1) + 20
Examples:
1st Mii (MiiOrder = 1)
MiiID start at = 92 x (1 - 1) + 20 = 20 = 0x14 (row 0x10, column 0x04) --> 94 BD 74 9E
2nd Mii (MiiOrder = 2)
MiiID start at = 92 x (2 - 1) + 20 = 112 = 0x70 (row 0x70, column 0x00) --> 94 BD 80 02
Just for checking, after MiiID, you could see the 3ds MAC address, e.g. CC FB 65 31 62 F4 (for these two Miis).
And from MiiID, we actually could calculate the exact time/date when that Mii is created.
Examples:
1st Mii (0x94BD749E & 0x0FFFFFFF) * 2 = (0x04BD749E) * 2 = 0x097AE93C = 159050044 seconds.
159050044 seconds + 1262304000 seconds (adding this for getting back to 1/1/1970 00:00:00) = 1421354044 seconds or Thu, 15 Jan 2015 20:34:04 GMT (using http://www.onlineconversion.com/unix_time.htm).
2nd Mii (0x94BD8002 & 0x0FFFFFFF) * 2 = (0x04BD8002) * 2 = 0x097B0004 = 159055876 seconds.
159055876 seconds + 1262304000 seconds (adding this for getting back to 1/1/1970 00:00:00) = 1421359876 seconds or Thu, 15 Jan 2015 22:11:16 GMT.
From these examples, we could see that older Mii may have MiiID starts with a number different than 94. To make older Mii to have gold pants just changing from the first number in the first byte of MiiID to 1 (e.g. 93 to 13, 92 to 12, etc).

Disable sharing bit located at byte = 92 x (MiiOrder - 1) + 56
Examples:
1st Mii (MiiOrder = 1)
Disable sharing bit is located at byte = 92 x (1 - 1) + 56 = 56 = 0x38 (row 0x30, column 0x08) --> 01
2nd Mii (MiiOrder = 2)
Disable sharing bit is located at byte = 92 x (2 - 1) + 56 = 148 = 0x94 (row 0x90, column 0x04) --> 01
We could see that both Miis have already disable sharing bit set (i.e. they are already an odd number).

Hope that helps.

I have tried it on win 8 64 bit and win 7 and both get the same error....

AquaX101 · Feb 8, 2015

Is this compatible with cfw? (Not like it matters for me because I own a copy of cubic ninja, but I just would like to know)

If you convert it to a cia I don't see why not

Its not the fact that its a cia, its the extra data of the cfw itself.

I got excited, until I saw the Cubic Ninja requirement... Fucking lamesauce. >.<

You can use GW and a .3ds file with a custom config.txt

I'm on 9.2U (With 9.5U nag screen) on a 2DS, and no Gateway, Cubic Ninja, or Sky3DS. So if people could just make this shit work with the browser exploit, that'd be great...
