Patch Note for version 8 :

Checksave script: to avoid the super annoying problem of the save that doesn't let you keep playing after the league, a script forces you to solve the problem right from the beginning. If you can't save, you can't play. So, make sure to adjust the options of the emulator as explained in the Poke Community, Fandom and FB page.
