Tomorrow

Hello Guys, Sorry if this has been asnwered to from a different post. I have started editing Ultra Sun and when I started rebuilding .3DS file i kept getting a fault. I have narrowed it down to when I replace typing of the pokemon or adjusting there stats. Anyone knows how to fix this? Thanks

Hello Guys, I've recently started doing this and happily done my own edits on ORAS but now I am doing editing on USUM. Does PK3DS has issue on changing Pokemon Typing on USUM? Because I change some pokemon type and it wont let me rebuild .3ds, I've tried installing decrypted, CIA and encrypted roms to make sure it's not the rom itself but at the moment I am having trouble rebuilding the USUM Rom after I've done changes to it
