Where is the checked creator/source route?
Developer changelogs and save guidance

No. The developer states that taking the newest patch keeps your save compatible. One caveat he gives: NPC positions fixed in a newer patch do not change retroactively inside an existing save.
Are TMs reusable in Pokémon Run & Bun?
No. TMs are single-use by design, although the developer says a few can be obtained infinitely at the Lilycove Department Store later in the game.
Can I use PKHeX with Pokémon Run & Bun?
The developer says it is not really compatible and recommends not using it at all with this game. There is no debug mode either.
Can I change IVs and natures?
Yes, but it costs Heart Scales, which the developer describes as a limited resource.
