Hello, I hope that some staff, Mod or supervisor of this game knows this and knows how to fix it.
In PokeMMO (I don't know if you know this), when you go to Hoenn or Kanto the game closes by itself, and makes you put the Roms back in and it's a very annoying thing because when I want to do something in Kanto or Hoenn I can't because of this bug . I hope you can solve it thanks for your attention.
