Pokémon Sacred Gold & Storm Silver — Documentation & Project Notes

Introduction These fan-made ROM hacks—Pokémon Sacred Gold and Pokémon Storm Silver—are enhanced, expanded versions of Pokémon HeartGold and SoulSilver. They add new story content, rebalanced encounters, updated difficulty, restored cut content, and many quality-of-life improvements. This post documents what the hacks change, how they’re organized, technical details for patching and testing, and notes for anyone maintaining or contributing to similar ROM-hack projects.

What these hacks aim to do

• Restore and expand: Reintroduce or rework content cut from the original games, expand postgame areas and storylines, and add new events.
• Rebalance gameplay: Adjust wild encounters, trainer teams, gym leaders, and Elite Four to create a more challenging and varied experience.
• Modernize mechanics: Implement convenience features (e.g., faster text, improved move tutors, adjusted TM/HM usage) and compatibility with later Pokémon generations’ mechanics where feasible.
• Polish UX: Improve menus, item placement, NPC dialogue, and bug fixes from the original base.

Major content changes (high-level)

• New trainer rosters and difficulty scaling across the map and postgame.
• Altered wild encounter tables for early and late-game routes, with more variety and higher level ranges.
• Reworked gym leader/Elite Four teams, often including new movesets, items, and EV spreads.
• Additional scripted events, sidequests, and expanded postgame areas (e.g., Team Rocket extensions, extra Legendary encounters).
• Rebalanced TM/HM distribution and new move tutors allowing broader move access.
• Restored or rewritten NPC dialogue to clarify story beats or hint at secrets.

1. Patch logistics

• Base ROM: HeartGold or SoulSilver (U, J, or E versions). The hacks are patches in IPS/UPS format—apply with a patcher such as Lunar IPS or NUPS.
• Target ROM hash: Always verify the original ROM CRC32/SHA1 before patching to ensure compatibility. The documentation should list exact accepted base-ROM builds.
• Patch distribution: Provide only IPS/UPS patch files and patching instructions; never distribute copyrighted ROM files.

2. File and asset map

• Script files: Organized by area and event (e.g., ECRAN_CITY_EVENT.s, ELITE4_EVENT.s).
• Map files: Route and city maps, tilesets, and map headers. Note any custom tilesets added for new areas.
• Trainer and wild data: Separate tables for wild encounters, trainer parties, trainer classes, and prize money. Include CSV/JSON exports for easy review.
• Pokémon data: Moves, learnsets, base stats, evolutions—highlight any custom or altered Pokémon.
• Items: TM/HM placements, held items on trainers, item pool changes.
• Graphics/audio: Any new sprites, palette edits, tiles, or music reassignments must be cataloged with filenames and usage points.

3. Gameplay changes (detailed)

• Wild encounters: For each route, list previous encounter slots vs. new slots, frequency weights, and level ranges. Provide rationale (e.g., early-route expansion to introduce type variety).
• Trainer rosters: For each major trainer/gym leader, list pre-hack team and post-hack team, including levels, held items, abilities, moves, and AI behavior where modified.
• Bosses/E4: Show adjusted level curves and designed counters so players face progressively tougher strategies.
• Move accessibility: Document any TM changes and new tutors, including locations and availability windows.

4. Story and scripting changes

• New scenes: Describe added cutscenes, NPC interactions, and branching choices. Provide script excerpts for key beats and note file locations.
• Restored content: Note any canonical cut content that was reintroduced or reconstructed, and explain sources (debug scripts, leftover assets).
• Postgame: Outline new quests, objectives, and triggers—where to find them in scripting files.

5. Technical implementation notes

• Map edits: Describe tools used (e.g., Tiled, the Pokémon map editor used), custom tileset creation, and collisions. Provide guidance on inserting and linking new maps to the world map.
• Scripting language & conventions: Explain the scripting system used (e.g., XSE-style scripts), label conventions, and best practices for branching and flags.
• Trainer and battle tables: Explain binary formats used, offsets, and how to add or edit trainer parties safely.
• Data limits & pointers: Document pointer tables, free space usage, and recommendations for repointing or compressing assets to avoid conflicts.
• ROM-hack toolchain: List the primary tools (map editors, script compilers, hex editors, tile editors, music tools) and preferred versions or settings. Include recommended workflow: backup ROM → patch base → test each module in emulator → log bugs.

6. Testing checklist and QA notes

• Pre-patch verification: Confirm base ROM checksum, metadata, and emulator compatibility.
• Smoke tests: Walk through each major region to confirm no hard crashes, missing sprites, or infinite loops.
• Event tests: Trigger every new and modified event in isolation and as part of normal progression.
• Battle tests: Verify each gym leader and Elite Four team battle, confirm held items, AI, and level scaling.
• Edge cases: Validate evolution triggers, trade evolutions, day/night scripts, and time-based events.
• Save compatibility: Ensure save files from unpatched ROMs aren’t loaded into patched ROMs; document save format differences.
• Regression log: Keep a changelog of fixed issues and remaining known bugs with reproduction steps.

7. Contribution guidelines & changelog example

• Repo structure: Keep scripts, maps, trainers, and assets in clear folders with readme files. Use a changelog (e.g., CHANGELOG.md) with date-stamped entries.
• Pull request policy: Small, focused PRs; include before/after CSVs for trainers/encounters and a QA checklist.
• Testing contributions: Contributors should include emulator save states demonstrating the change.
• Attribution: Credit original authors and list community resources used (disassembly, documentation pages, tool authors).

Example changelog entry

• 2026-04-07 — v1.2.0
  • Expanded Route 34 encounter table; added early Steel-type encounters for balance.
  • Reworked Falkner (Gym) AI and moveset; increased team levels by +3 on average.
  • Added Team Rocket postgame mission with two new maps and three scripted battles.
  • Fixed bug: scripted item flag preventing Moltres encounter.

Maintenance notes and long-term roadmap

• Keep backups of original data tables before making wide edits.
• Periodically re-audit pointer and free-space usage when adding new assets to avoid corruption.
• Consider modular patches: split gameplay, story, and QoL into separate patches so users can opt in.
• User feedback loop: Track common complaints (difficulty spikes, missing encounters) and address with hotfix patches.

Legal & ethical considerations (concise)

• Distribute only patch files (IPS/UPS), not original ROMs.
• Respect IP: clearly label these as fan works and include disclaimers as needed.
• Avoid enabling cheating or piracy—provide only legitimate patching instructions.

Closing notes This documentation is intended to serve as both a technical reference for maintainers and a readable summary for players curious about what changes the Sacred Gold / Storm Silver hacks introduce. Keeping structured records, consistent naming, and a rigorous QA workflow makes collaborative ROM-hack projects sustainable and enjoyable for both creators and players.

For players venturing into the Johto region of Pokémon Sacred Gold and Storm Silver (SG/SS), the official documentation is as essential as a Pokédex. Created by the legendary ROM hacker Drayano, these games transform the original HeartGold and SoulSilver into a "complete" experience where all 493 Pokémon are obtainable and the difficulty is significantly ramped up.

Below is a comprehensive breakdown of the documentation work that defines this classic ROM hack experience. 1. The Core Documentation Files

When you download the official patch, it typically comes with a suite of PDF and text files. These documents are the primary "work" of the project, detailing every change to ensure players aren't flying blind.

Step 3: Cheating the EV System

Because bosses have perfect IVs and 252 EVs, you must EV train. The Location Doc tells you where to find specific EV yields.

• Need HP EVs? The doc says Route 31 has high-level Wooper.
• Need Speed? Route 32 has Rattata and Pidgey.

Part 3: Breaking Down the Core Documents

The standard documentation package usually comes as a .zip file containing several .txt files or .xlsx spreadsheets. Here is what each piece of "documentation work" covers:

Overview

This document surveys and documents the fan-made ROM hacks "Pokémon Sacred Gold" and "Pokémon Storm Silver." It provides detailed descriptions of features, gameplay changes, technical modifications, compatibility notes, installation guidance, and suggestions for further research or preservation. Intended audience: ROM hack players, preservationists, modders, and researchers.

The Challenge: Keeping 800+ Changes Straight

The sheer scale of the documentation work is staggering. Sacred Gold/Storm Silver modifies over 80% of the game’s data. Creating the documentation requires:

• Reverse Engineering: Using tools like PPRE (Pokémon Pearl ROM Editor) or SDSME to extract raw data.
• Manual Verification: Playing through the hack multiple times to ensure a "Rare" encounter actually appears at a 5% rate, and that a Gym Leader’s AI uses the correct move.
• Version Control: Drayano has released multiple versions (v1.05, v1.1, v2.0, etc.). Each update requires re-checking every single line of documentation to ensure a fix in the code matches the note in the PDF.

A single typo in the documentation—such as listing a "Moon Stone" on Route 32 instead of Route 34—can send players on a frustrating, hours-long wild goose chase.
