About This ROM Hack
Pokémon Soulgold is a Johto-focused Pokémon Emerald ROM hack built using pokeemerald-expansion and based on an unofficial expansion port of Heart & Soul. Rather than recreating HeartGold and SoulSilver exactly, the project delivers a traditional Pokémon adventure with a greatly expanded Johto region, modern battle mechanics, extensive quality-of-life improvements, and brand-new content while preserving the classic feel of the series.
Currently available as Beta v0.9.8.7, the hack is under active development, with frequent updates and bug fixes planned. The developer has confirmed that save files are intended to remain compatible between future versions, so players can continue their adventure without restarting.
The game modernizes the Johto experience by introducing mechanics from newer generations, including the Fairy type, Mega Evolution, following Pokémon, DexNav, the Physical/Special Split, revised trade evolutions, reusable TMs, optional level caps, difficulty settings, a day/night cycle, and numerous battle improvements. Alongside these features are entirely new systems such as achievements, Hidden Grottos, powerful Boss Pokémon encounters, expanded post-game content, and customizable gameplay options.
Visually, Soulgold features an entirely refreshed Johto tileset, new graphics, updated interface elements, custom battle backgrounds, and modern menus, creating an experience that feels both nostalgic and contemporary. The result is a ROM hack that stays true to Johto while offering significantly more content, exploration, and replayability than the original games.
Story Overview
Pokémon Soulgold follows the traditional Johto storyline while expanding the overall adventure with additional story content, new areas to explore, and extra events throughout both the main game and post-game.
Rather than completely rewriting the original narrative, the hack builds upon it by introducing new experiences that complement the familiar Gym challenge and Team Rocket storyline. Players can continue exploring well beyond the Pokémon League through expanded post-game content, legendary encounters, and additional gameplay systems that provide more reasons to revisit Johto after becoming Champion.
