[Question]Setup Server based on Ragnarok Episodes

[esquilla13]

Hey guys. I dunno if this was the right section to post this. Sorry if this was not the right place. Anyways, as the title says. I'd like to make a server based on a specific episode in ragnarok official server like for example I want to start the server at Episode 3(iRO: Comodo). What files should I work on to accomplish this? Thanks in advance.
