This guide details how to install EmuDeck and play Game Boy games on your Steam Deck, optimizing performance with Decky Loader and Power Tools. The Steam Deck, while powerful for modern gaming, also excels at retro gaming with the right setup.

Before You Begin:

You'll need:

• A fully charged Steam Deck.
• An A2 microSD card for games and emulators.
• Legally obtained Game Boy ROMs.
• A Bluetooth or wired keyboard and mouse (recommended for easier navigation).

Enable Developer Mode and CEF Debugging on your Steam Deck (instructions within the original article).

Installing EmuDeck:

Follow these steps in Desktop Mode:

1. Download EmuDeck from the official website.
2. Choose SteamOS and a custom installation.
3. Select your SD card as the primary installation location.
4. Choose your desired emulators (RetroArch, Emulation Station, Steam ROM Manager are recommended).
5. Enable AutoSave.
6. Complete the installation.

Quick Settings (EmuDeck):

Within EmuDeck, enable AutoSave, Controller Layout Match, Bezels, Nintendo Classic AR, and LCD Handhelds.

Adding Game Boy Games:

Using Dolphin File Manager, navigate to Primary > Emulation > ROMs > gb and transfer your .gb ROMs. Ensure correct filenames.

Using Steam ROM Manager:

Within EmuDeck, use Steam ROM Manager to add your Game Boy games to your Steam library. This will allow launching games directly from your Steam library.

Playing Game Boy Games:

Access your Game Boy games through your Steam Library's Collections tab.

Customizing Game Colors (RetroArch):

Many Game Boy games support colorization via RetroArch. Access this through the RetroArch menu (Select + Y buttons).

Using Emulation Station:

Alternatively, launch games through Emulation Station (found in the Steam Library's Collections tab).

Installing Decky Loader:

Install Decky Loader from its GitHub page in Desktop Mode. Restart your Steam Deck afterward.

Installing Power Tools:

Install the Power Tools plugin through the Decky Loader store.

Power Tools Settings:

Disable SMTs, set Threads to 4, enable Manual GPU Clock Control (set to 1200 MHz), and utilize Per Game Profiles for optimal performance.

Restoring Decky Loader After a Steam Deck Update:

Reinstall Decky Loader from its GitHub page if necessary after a Steam Deck update.

Enjoy your enhanced Game Boy gaming experience on your Steam Deck!
