Ultimate Region ID Cycler In Between Races [Vega]

This is similar to other "Change Region ID in between Races Online" Codes but it also changes your Flag + Globe Location, and you will see the effects also occur on your own screen (other Change Region ID codes will only update the effects on the opponents' screens).

I have made this code in honor of Nutmeg who was the first person ever (in Feb 2012) to change Region ID's in between races online.

This code will cycle through all 7 Region IDs in ascending order and then repeat once China has been used. It's automated, no button activators required. Your Region ID, the Region ID's default geo-location, and your flag image (if applicable) will cycle after every single race. Everyone will see the effects.

NOTE: There is a small side effect. Before you do your first race, if you view your Mii on the globe, it will have the country's flag image turned on (if applicable) even if it's off in your Wii settings.
