CRC-16 in RFL_DB.dat

Hi --

I'm trying to change the Client ID of a couple Miis to match the NAND's Client ID. No problem. But now I need to update the checksum. According to this page...

wiibrew.org/wiki//shared2/menu/FaceLib/RFL_DB.dat

... I need to update 0x1f1de & 0x1f1ef with the CRC-16 of 0x0 through 0x1f1dd. And I've found proof of the latter. If I delete a Mii using the Mii Channel and diff the previous RFL_DB with the updated one, the only change (outside of the section with the deleted Mii being zeroed out) is to 0x1f1de & 0x1f1ef. However, I don't think the range used for the checksum is correct?

No HEX editor I've used is "correctly" calculating the CRC-16 for what the Wii expects. So I'm unable to make any edits to the file, as it will be determined to be corrupted by the Wii.

I was wondering if anyone could shine some light on this? It'd be much appreciated!! :luigi1:

Why are you editing this file directly?

I'd just use Mii Extractor to save all Miis to SD, then you can use normal Mii editing tools (IIRC the mii files don't even have a checksum!) and then you can re-import them with Mii Installer.

I actually tried doing that, but I end up losing my save data from the Wii Sports player list! Which is kind of a big deal to me, haha.

This would probably also happen when you edit the mii IDs in the file directly, because the Wii Sports save data is linked to the Mii ID.

Hmmm, do you know if it's linked to Avatar ID, Client ID, some combination of the two, or something different?

It is definitely linked to the Mii ID / Avatar ID; but I don't know if it is also linked to the system ID. I'd expect it to be.
