Compared a converted 1337 scenario, the original EU2 1419 scenario, and the current conversion files, and came up with this new culturechanges.txt. (Note: this is for DVIP, and assumes you have the berber culture already.)
However, this leads to a rather annoying problem: the converter itself uses the original cultures from CK rather then the overrides in culturechanges.txt. It's most noticeable with nations like Slovakia (which might have slovak provinces but only czech culture), Albania (ditto with albanian and greek/slavonic), Syria (syrian and arabic/turkish respectively), and Kiev/Ukraine (ruthenian and russian).
That's easily fixed with events or just manually editing the save though.
