Hello Mad!, thanks for answering but sadly the original quest files for PSOBB are stored in the server as far i know.
The client downloads the 'qst' files when you start a quest at the hunters guild and then proceeds to start it, hence the reason why I think it's gonna be a daunting task to find those files specially the Goverment quest ones (1-2,1-3,1-4,etc)
Maybe there's a tool to 'capture' the quest files while it's being downloaded somehow?
@ Neirene - I have a ton of Japanese quests, stashed on an old hard drive of mine, somewhere. I'm very doubtful, I have any of the JP Gov quests though. However, the quests I have, are not in .qst format, but in .raw format. If your interested, feel free to pm me.
