Route plan

Use Repels if low on resources; without Flash, hug walls and follow ladders methodically.

Route Notes

  • Rock Tunnel's trainer density is high, making it a good VS Seeker/EXP route later.

Wild Pokemon

Version

Each area below has its own table, split by encounter method. Standard wild rows merge every slot for a species into one line with a combined rate, and FireRed/LeafGreen exclusives are marked with FR/LG game chips; there is no time-of-day split in these remakes. Underlying slot odds: grass and cave 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Rock Smash 60/30/5/4/1; Old Rod 70/30; Good Rod 60/20/20; Super Rod 40/40/15/4/1. Gift, static, trade, and prize Pokemon keep their own labeled rows.

  • Check the wild table for FireRed/LeafGreen version splits, rod methods, Surf, Rock Smash, static Pokemon, gifts, trades, and event-only rows when present.
  • Defeat or intentionally skip optional trainers; use VS Seeker notes where rematches are available.
  • Sweep visible and hidden item rows, including key items, HMs, TMs, berries, fossils, and scripted gifts.
  • Review boss cards and heal before any Rival, Gym Leader, Rocket Admin, Elite Four, Champion, or legendary encounter listed above.
