That is fine. I just changed the MX one to use the same reference for descriptor so for now it is easier than to figure out the country.

Then how should it be done for upcoming NA releases, since there could be up to 5 versions in the region: USA (ESRB, English), Canada (ESRB, English/French), Brazil (English and/or Portuguese, ClassInd), Mexico (Spanish, SMECCV), and the rest of Latin America (English and/or Spanish, ESRB)? Do we still default Latin America for old releases (pre-SMECCV) as MX (English and/or Spanish, ESRB), unless specified in the box, and something new for the rest of the region?
