Ultimate Region ID Cycler In Between Races [Vega] - Vega - 02-12-2019

Ultimate Region ID Cycler In Between Races [Vega]

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. Nutmeg would also change the default geo-location too, not just the Region ID line color itself. Only thing he didn't change was the flag image if said Region ID had one, which I decided to include in this code since I like the look of the flag images.

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 (on your screen AND opponents' screen) along with the Region ID's default geo-location, and your flag image (if country code has a flag available) will cycle after every single race.

For example, your first race online will have all your normal Region ID, flag, and globe settings. But once you go to the next race of the session, your Region ID value will increment by 1 (the Region ID's default geolocation will be applied, and flag too if available). This cycle will repeat once per race. Once China's Region ID is used, the cycle will reset at Japan's Region ID.

Let's say you end your current WW session, and you were at Korea Region ID from the last cycle. You will see that you will now be at Seoul, S.Korea with the Korean Flag on the globe. Opponents will see these effects too if you are in a Room. Obviously whatever Region ID cycle you are on during the middle of a WW session, opponents will see the current Region ID Cycle's Globe & Flag settings when they join your WW.

NOTE: This code makes use of memory addresses 0x80001648 thru 0x8000164B, make sure no other codes you have on are using those addresses!
