Automated Friend Code Display Cycler [Vega]

This code will auto increment your Friend Code Displayed Value in the Check Friend Code menu. It will increment all the way up to 9999-9999-9999 then reset to 0 and repeat forever. Everything is automated.

Note: This code makes use of memory addresses: 0x80001650, 0x80001654 thru 0x8000165B. Make sure no other codes in your GCT/Cheat-Manager are using those memory addresses!
