Hoo boy, I dun messed up.
So I deleted a buncha mIis, left two Miis (personal and a clone), changed 91 into 11 for each, restored them... and now they're not brown pants, but blue pants. Meaning the 3DS recognizes them as someone else's Miis, and therefore won't let me edit NOR use them with Streetpass Plaza.
So yeah, not gold pants, but fucking blue jeans. MFW I am dumb as rocks right now somebody help plox.
Uploading screenies of the data sections for both personal mii and clone. Kindly point me to the right row/column to change, and how do I make them editable again? Oh yeah, the highlighted parts are the parts I changed, so I changed them back to 9s instead of 1s, then re-applied fixcrc.
Thanks!
EDIT: NAILED IT! Goldie pants for fancy pants #1 and #2, mofos! Woot! Hehehehe...
Now all that's left is figuring out how to fix Mii Maker to Home Menu and creating that elusive QR code. Btw, figured a Mii's data starts with a [00 03 00], and lucky for me they both started at the same column, so I can identify the proper bits to change through their positions. Starting from the 03, count the first 00 as ONE, then continue counting to TWELVE. That's the one you want to change for goldie pants, then FROM THERE count to THIRTY SIX, and that's for Disable Sharing.
