Genhax was released by Mr svanheulen several days ago and it is a new 3ds secondary homebrew exploit based on Monster Hunter Generations game. It works for the JPN, EUR and USA regions of the game, using the latest game updates. You can only use it on NEW3DS console(From 9.9.0-X(JPN) or 10.3.0-X(EUR/USA) up to and including 11.2.0-X.)
There are some notable limitations for this exploit:
■ It only works on New 3DS systems.
■ It must be installed on the system you want to use it on. This is because
the exploit uses the game’s ExtData which is stored on the SD card, not the game cart.
■ You will no longer be able to post certain quests in the Hunters Hub. If
you install the exploit as an event quest, you won’t be able to post event
quests. If you install the exploit as a challenge quest, you won’t be able to
post challenge quests. But you should still be able to join event/challenge
quests that other players post.
