change of MAC-address results in Miis becoming uneditable
0%
Description
dolphin seems to generate it's emulated MAC-address from the first network-adapter of the system it is running on.
thus any change of the network-adapters on the host-system can result in a change of dolphin's MAC-address. this can happen easily by e.g. adding or removing bluetooth-adapters, Wlan-adapters or virtual adapters, installing a VPN- or VM-software, etc.
now when a Mii is created via the Mii channel, a system ID is saved with it, defining this system as the "owner" of the Mii. this system ID seems to get generated via dolphin's MAC-address. only the "owner" of a Mii is able to edit it.
this results in the following problem:
a change of the network-configuration of the host system results in a change of the MAC-address of dolphin, which again results in the Miis becoming uneditable.
steps to reproduce:
- create a Mii
- find the first network-adapter on your system (e.g. on windows via command "ipconfig /all").
- deinstall this network adapter.
- try to edit the Mii - this should now not be possible.
suggested solution:
make the MAC-address fixed, or even configurable in the settings. this way any change of hadware or software would not change dolphin's MAC-address and the Mii's will stay editable.

mii's contain the mac address of the system they were created on to verify ownership. I would suggest changing this address in the mii data yourself see http://wiibrew.org/wiki/Mii_Data for information on the format.

thanks for the info, i've already invested some time finding such a solution. it's actually not the MAC-address itself, that is written in the MII-data, but a system ID, which is derived from the MAC-address.
changing this system ID in the RFL_DB.dat file results in the Mii- and Savegame-Data becoming corruted. i think that's because there is a checksum later in the file, but i haven't found out yet, from which data the checksum is generated.
but on the other hand - even if a doable solution is possible, fiddling around with a HEX-editor everytime the network configuration changes is imho not really a good solution for this problem for the majority of users, and it rather counters the symptoms, and not the source of the problem.
my guess is, that implementing a fixed or configurable MAC-address in dolphin would put a definite end to this problem.

If you know how to code, you could add code there to make this configurable.
Mind you, the wii-network branch (which still is a WIP) "fixes" this issue by hardcoding the mac address.

Looks like it should be easy to add an option for this.

yay, many thanks rdragoon for the quick implementation! this is working great! :)
i've now also found a quite lengthy manual procedure to change the system IDs and thus "re-own" Miis to ones System. i've documented the necessary steps here:

after having done that your commit makes sure the Miis stay editable forever. :)
