Pokemon Lazarus on Steam Deck - Complete Setup Guide

Why Play Pokemon Lazarus on Steam Deck?

The Steam Deck is the perfect device for Pokemon Lazarus:

• Portable Perfection: Play anywhere with 2-8 hour battery life
• Full Controller Support: Native gamepad controls feel amazing
• Perfect Performance: GBA emulation runs flawlessly at 60fps
• Save States: Quick save/load anywhere in your adventure
• Big Screen Ready: Dock it to play on your TV

Pokemon Lazarus was designed for handheld play, making the Steam Deck the ideal modern platform for this incredible ROM hack.

Method 1: EmuDeck Installation (Recommended)

EmuDeck is the easiest way to get Pokemon Lazarus running on Steam Deck. It automatically installs and configures all emulators, including mGBA for Game Boy Advance games.

Step 1: Download EmuDeck

1. Open Steam Deck in Desktop Mode (hold Power button → Switch to Desktop)
2. Open the Firefox browser (should be pre-installed)
3. Go to https://www.emudeck.com
4. Click "Download EmuDeck for Steam Deck"
5. Save the file to your Desktop or Downloads folder

Step 2: Install EmuDeck

1. Double-click the downloaded EmuDeck.desktop file
2. Click "Continue" when the security warning appears
3. Select "Easy Mode" (recommended for beginners)
4. Choose installation location:
   • Internal Storage: Faster but limited space (64GB/256GB/512GB)
   • SD Card: More space but slightly slower (recommended for large game libraries)
5. Wait for EmuDeck to download and install all emulators (5-15 minutes)
6. Click "Finish" when installation completes

EmuDeck installs mGBA automatically, which is the best GBA emulator for Steam Deck performance.

Step 3: Download Pokemon Lazarus ROM

1. While still in Desktop Mode, open Firefox browser
2. Visit the Pokemon Lazarus Download Page
3. Click "Download Pokemon Lazarus v1.0"
4. Save the PokemonLazarus.gba file (or extract if it's a .zip)
5. Move the ROM file to your EmuDeck ROMs folder:
   • Internal Storage: /home/deck/Emulation/roms/gba/
   • SD Card: /run/media/mmcblk0p1/Emulation/roms/gba/

Pro Tip: You can use the Dolphin File Manager (pre-installed) to navigate to these folders easily!

Step 4: Add Pokemon Lazarus to Steam Library

1. In Desktop Mode, open Steam (from the taskbar)
2. Click "Games" → "Add a Non-Steam Game to My Library"
3. Click "Browse"
4. Navigate to your ROMs folder: /home/deck/Emulation/roms/gba/
5. Change file type filter to "All Files" at the bottom
6. Select PokemonLazarus.gba
7. Click "Add Selected Programs"
8. Right-click the game in your library → "Properties"
9. In the Target field, change it to:

   /home/deck/Applications/mGBA.AppImage %command%

10. In the Start In field, enter:

    /home/deck/Emulation/roms/gba/

11. Rename the game to "Pokemon Lazarus" in the properties

Alternative Method: EmuDeck includes Steam ROM Manager which can automatically add all your ROMs with artwork! Run it from Desktop Mode.

  • Set Integer Scaling for authentic pixel-perfect look
• Sound: Enable Sample Rate: 48000Hz for best audio quality
• Fast Forward: Use 2x-4x speed for grinding and long routes
