the country codes are in those versions:

1: the normal state, only 1 language in the rom
2: the rom is Multilanguage, x is the number of languages in the rom
3: the release is officially a C country, but the rom serial is B country
4: as the 3rd point, but in this case we have a multilanguage rom (as explained in 2nd point)
