This is a Quest Editor for Monster Hunter Generations Ultimate and Monster Hunter XX (Nintendo Switch Version)

• Direct Quest Arc loading
• Auto-updating quest lists (vq.arc/gq.arc/gq2.arc/tq.arc)
• Quest Data editing (Main Quest Data found in .ext/.mib files)
• Quest Info editing (Text Displayed, found in various .gmd files)
• Quest Rewards editing (Found in .rem files)
• Small Monster spawn editing (.esl files)
• Large Monster spawn editing (.sem files)
• Supply Item editing (.sup files)
• QuestPlus editing (Arena Fence timers, Fort HP, etc. .qpl files)
• Adding new quests to the game

I suggest first setting a path to a quest list in the settings and enabling the auto-update feature. Then you can start editing quests by opening a quest arc (qXXXXXXX.arc).

For files that are currently unsupported, you can edit them using a hex editor. If you're using 010 Editor you can find templates for many of the files here.
