What You'll Need

Before we begin, make sure you have:

  • A computer (Windows, Mac, or Linux)
  • A legal ROM of the base Fire Emblem game
  • The mod patch file (usually .ups, .ips, or .bps format)
  • A patching tool (we'll use Floating IPS for this guide)
  • An emulator to play the patched game (mGBA, VBA-M, or similar)
  • About 15-30 minutes depending on your experience level

⚠️ Important Legal Note: You must own a legitimate copy of the Fire Emblem game you're modding. This guide assumes you're using legally obtained ROMs from games you own.

Understanding ROM Patches

What is a ROM Patch?

A ROM patch is a small file that contains the differences between the original game and the modified version. Instead of distributing entire modified ROMs (which would be illegal), mod creators share these "patch" files that you apply to your own legal ROM copy.

Common Patch Formats

  • UPS (.ups) - Most common for GBA Fire Emblem mods
  • IPS (.ips) - Older format, still widely used
  • BPS (.bps) - Newer format with error checking
  • XDelta (.xdelta) - Advanced format for larger patches

Step 1: Obtaining Your Base ROM

Finding the Right ROM Version

Different mods require specific ROM versions. Always check the mod's requirements:

  1. Fire Emblem: The Blazing Blade (FE7)

    • Japanese version: Fire Emblem - Rekka no Ken (Japan).gba
    • US version: Fire Emblem (USA).gba
    • European version: Fire Emblem (Europe)(En,Fr,De,Es,It).gba

  2. Fire Emblem: The Sacred Stones (FE8)

    • US version: Fire Emblem - The Sacred Stones (USA).gba
    • European version: Fire Emblem - The Sacred Stones (Europe)(En,Fr,De,Es,It).gba

  3. Fire Emblem: The Binding Blade (FE6)

    • Japanese version: Fire Emblem - Fuuin no Tsurugi (Japan).gba

Verifying Your ROM

Most mods will specify the exact ROM they need, often with a checksum. You can verify your ROM using tools like:

  • HashTab (Windows)
  • HashCheck (Windows)
  • Terminal commands (Mac/Linux): md5sum filename.gba

Screenshot Reference: You should see a dialog showing file properties with hash values

Step 2: Downloading the Mod Patch

Where to Find Mods

  • FEUniverse - The largest Fire Emblem modding community
  • ROM Hacking.net - General ROM hacking repository
  • Serenes Forest - Fire Emblem community with mod section
  • GameBanana - Game modification platform

Downloading the Patch

  1. Navigate to the mod page
  2. Read the requirements carefully
    • Base ROM version needed
    • Any additional tools required
    • Known issues or compatibility notes
  3. Download the patch file
    • Usually a .zip or .rar archive
    • Extract to a folder you'll remember

Screenshot Reference: Show a typical mod download page with requirements and download button highlighted

Step 3: Setting Up Your Patching Tool

For this guide, we'll use Floating IPS (FLIPS) - it's free, reliable, and works with all major patch formats.

Download and Install FLIPS

  1. Visit the FLIPS download page: https://www.smwcentral.net/?p=section&a=details&id=11474

  2. Download the latest version

    • Windows: Download the .exe file
    • Mac/Linux: Download the appropriate version

  3. Extract and run

    • No installation required!
    • Just run the .exe file directly

Screenshot Reference: Show the FLIPS download page and the simple interface when first opened

Alternative Tools

Step 4: Applying the Patch

Now for the main event! Here's how to patch your ROM step-by-step:

Using Floating IPS (FLIPS)

  1. Open FLIPS
    • Double-click the flips.exe file
    • You'll see a simple window with three options

Screenshot Reference: FLIPS main window showing "Apply patch", "Create patch", and "Apply BPS" options

  1. Click "Apply patch"

  2. Select your patch file

    • Browse to where you extracted the mod
    • Select the .ups, .ips, or .bps file
    • Click "Open"

Screenshot Reference: File browser window showing various patch files with extensions highlighted

  1. Select your base ROM
    • Browse to your original Fire Emblem ROM
    • Make sure it matches the mod requirements exactly
    • Click "Open"

Screenshot Reference: File browser showing ROM files with proper naming conventions

  1. Choose output location
    • FLIPS will ask where to save the patched ROM
    • Important: Give it a new name (don't overwrite your original!)
    • Example: Fire Emblem - Vision Quest.gba
    • Click "Save"

Screenshot Reference: Save dialog with a clear example of renamed output file

  1. Patching process
    • FLIPS will show a progress bar (usually very quick)
    • You'll see "The patch was applied successfully!" if it worked
    • If there's an error, see the troubleshooting section below

Manual Process Summary

Original ROM + Patch File → Patching Tool → New Patched ROM
    ↓              ↓              ↓              ↓
[fe7_original.gba] + [vision_quest.ups] → [FLIPS] → [fe7_vision_quest.gba]

Step 5: Testing Your Patched ROM

Loading in an Emulator

  1. Download a GBA emulator if you don't have one:

    • mGBA (recommended) - Fast and accurate
    • VBA-M - Feature-rich alternative
    • RetroArch - Multi-system emulator

  2. Open your emulator

  3. Load the patched ROM

    • File → Open ROM
    • Browse to your patched .gba file
    • Click "Open"

Screenshot Reference: Emulator window showing the modded game's title screen

Verifying the Patch Worked

  1. Check the title screen

    • Modded games often have custom title screens
    • Look for the mod's name or logo

  2. Start a new game

    • Character names might be different
    • Opening dialogue may be custom
    • Maps and music might be changed

  3. Save and load test

    • Create a save state
    • Close and reopen the emulator
    • Verify the save loads correctly

Troubleshooting Common Issues

"Patch file is invalid" Error

Problem: FLIPS can't read the patch file

Solutions:

  • Re-download the patch (file may be corrupted)
  • Try a different patching tool
  • Check if you need to extract the patch from an archive first

"ROM checksum mismatch" Error

Problem: Your ROM doesn't match what the mod expects

Solutions:

  • Double-check you have the correct ROM version
  • Look for the exact ROM requirements in the mod documentation
  • Try a different ROM dump

"Failed to create output file" Error

Problem: Can't save the patched ROM

Solutions:

  • Check if you have write permissions to the destination folder
  • Make sure the destination drive has enough space
  • Don't try to overwrite the original ROM file

Game Crashes or Glitches

Problem: Patched game doesn't work properly

Solutions:

  • Try a different emulator
  • Check if the mod has known compatibility issues
  • Verify you followed all mod-specific instructions
  • Re-patch with a clean ROM

Can't Find Save Files

Problem: Your saves don't appear in the modded game

Solutions:

  • Emulator save files are tied to ROM filename
  • Rename your save file to match the new ROM name
  • Some mods intentionally start fresh (check documentation)

Advanced Tips

Managing Multiple Mods

  1. Organize your files

    Fire_Emblem_Mods/
├── Original_ROMs/
├── Patches/
├── Patched_ROMs/
└── Saves/

  2. Use descriptive names

    • FE8_Original.gba
    • FE8_Sacred_Stones_Complete.gba
    • FE8_Vision_Quest_v2.1.gba

  3. Keep notes

    • Track which patches you've applied
    • Note any special installation instructions
    • Record version numbers

Batch Patching

For multiple patches, consider:

  • FLIPS CLI mode for command-line batch operations
  • Custom batch scripts for repetitive tasks
  • Rom organization tools like CLRMAMEPro

Creating Backups

  1. Backup original ROMs - Never modify your originals
  2. Save state backups - Before major story events
  3. Multiple save slots - In case of corruption

Working with Different Mod Types

Complete Overhauls

  • Entirely new story, characters, and maps
  • Example: Fire Emblem: The Last Promise
  • Usually require clean ROM, may have multiple patches

Enhancement Patches

  • Improve graphics, balance, or add features
  • Example: Fire Emblem 8: Creature Campaign
  • Often compatible with other minor patches

Translation Patches

  • Convert Japanese games to English
  • Example: Fire Emblem 6 Translation
  • Apply before any other patches

Randomizers

  • Shuffle characters, items, or story elements
  • Example: Universal Fire Emblem Randomizer
  • Usually applied to already-patched games
