The story is the same as Emerald’s. Not much has been changed, so you can proceed with Run & Bun the same way you would proceed with Emerald’s original story.


The first thing is that the difficulty is very hard. It is close to unfair with enemy Trainers have access to strong Pokemon that you don’t have access to yet. There are some people saying that this hack is too hard, but there are those out there that love the masochistic challenge.

The roster and mechanics go all the way up to Gen 8. There are also field effects that will affect the battles that you encounter. EVs have also been removed, and there is an NPC near the PC that will Teach Moves, Max IVs, and change Natures for a fee.
