I made a tool to quickly check the real MAC change abilities of your wireless adapter driver in Windows.
Just download it from
http://nintendozone.no-ip.org/maccheck.cmd (If you can't download, check your browser security) and launch from the command line like this
Code:
maccheck.cmd "your wireless network connection name"
It will work for about 3 minutes, during this time the selected connection will be toggled off and on many times.
Some explanations about the result.
Any MAC - well, you're lucky
With bit1=0 you do not have limitation for a streetpass, all hardware MACs have this value
With bit2=1 you can use only the same locally set like Prime MACs but native Nintendo Zone and other users hardware MACs just can't be set by the driver, it will either fallback to the hardware MAC or change it with something different. So once again, DO NOT use any hardware MACs in that case.
If the result is a limited number of MACs, in most cases with any common MACs available you're able to get streetpasses from the people with the same drivers. The only thing we can do is to select the most common MACs for the variety of such drivers to be the new Prime MACs. So just
PM me the output and I'll gather it all.
If can't change, well, you can only report your MAC so others can visit you. No, you can't try other macshift/MacCycle/Mac-whatever- all are working over the driver which was just checked for the real MAC change.
