Enter Pokémon Sacred Gold and Storm Silver , the famous ROM hacks created by Drayano. These hacks are widely considered the gold standard for replaying Johto. They not only increase the difficulty and rebalance the game mechanics but also solve the availability problem. In these versions, all 493 Pokémon from Generations I through IV are obtainable within a single playthrough.
For many trainers, the Johto region holds a special place in their hearts. Pokémon Gold and Silver introduced the concept of a day/night cycle, a vast new world to explore, and the ability to travel back to Kanto. However, the original games—and even the official HeartGold and SoulSilver remakes—suffered from a common issue: the Johto Pokédex was limited, and many of the coolest Pokémon were unavailable until the post-game or were simply absent.
