you could try asking for it in the Feedback thread, https://www.speedrun.com/The_Site/thread/g79jt or in the bugs thread, as the site shouldhave all countries already... https://www.speedrun.com/The_Site/thread/onfz6

Which country may I ask ?

Uh, it is on the list, dude.

I actually just added it yesterday, coincidentally. It wasn't originally because it's not on ISO-3166.
