I deleted my old file today, and decided to RNG my ID/SID. After that had been done, I chose Chimchar at Lake Verity again. I trained him up a bit by battling around Sandgem Town, then advanced onto Route 202. I caught a Starly there, as I have a soft spot for them, then reached Jubilife City. I saved in the Pokémon Center.
