Will this work with my game version?
WeMod uses advanced technology to detect the game version you’re running and will let you know if it’s supported. If it’s not, you will still have the option of giving it a try or requesting an update!

could use a couple more features, still amazing though!!! requesting the ability to skip turns and ignore battles, maybe even insta-spare battles.
