I came across the following dialogue, which occurs right as the hero arrives:
「やっと来おったか。」
I'm not sure how to parse 来おった. Is it 来{き} + 居{お}る? If so, what exactly does this form mean? Do other verbs have a similar form?
Searching online, I see examples like とうとう来おった and ついに来おった, so my best guess right now is that the nuance is related to とうとう・ついに・やっと.
I've tried looking this up in paper dictionaries and online, but I'm having trouble finding it anywhere, so I thought I'd ask here!
