Here is a EmuDeck ROG Ally emulation guide to get all emulators set up on your ASUS ROG Ally with the proper configuration, bezels, hotkeys, performance fixes and more.
EmuDeck is a collection of scripts that allows you to autoconfigure your ROG Ally, it creates your roms directory structure and downloads all of the needed Emulators for you along with the best configurations for each of them.
EmuDeck ROG Ally Emulation Guide
Download and install the latest version of EmuDeck for Windows here.
Next you want to select what drive you want your ROM directory to be on.
Next you want to select the ASUS ROG Ally.
Choose what Emulators and Tools you want installed.
If you want to enable Auto Save for these specific emulators click On.
The next section will ask you to configure bezels and aspect ratios for specific emulators.
Choose the Frontends and themes you want to use to launch your roms. I personally use ESDE and Steam Library.
Next you want to select the resolution for each Emulator.
Next you want to wait for Emudeck to be installed on your ROG Ally.
Next you will have the option to enable cloud saves to sync between devices you run EmuDeck on.
You should now get a screen asking you to open up Steam Rom Manager. Before we do that, you want to drag all our roms and bios to their correct folders. Open up the drive you selected for your rom directory, open the Emulation folder, open the roms folder and start putting your roms into their proper folder.
Next you want to place all the bios files for the Emulators that need one in the bios folder inside your Emulation folder. You can learn more about what Emulator needs a bios on the EmuDeck wiki page here. You can find all bios files with a simple google search.
Updating Emulators in EmuDeck
Inside EmuDeck go to Manage Emulators, select the Emulator you want to update and then click reinstall/update.
Steam ROM Manager is a super flexible tool for adding non-Steam games to Steam in bulk and managing their artwork assets and controller templates.
After placing your Roms and Bios in their proper folder, Make sure Steam is completely closed. Open up EmuDeck again and click Steam Rom Manager.
Parsers let’s you toggle which emulators/games you want added to your Steam Library. Make sure to toggle EmulationStationDE. After toggling what you want in your Steam Library, click preview.
Click Parse to scan all the roms in your library and download artwork for each game. The emulators and games you toggled should show. You can edit artwork here or in Steam afterwards. Click Save to Steam and wait for the Done message to appear in the top right corner. You can exit Steam Rom Manager.
Restart the Steam app and you will see your Roms/Emulators in your Steam Library.
