Nintendo 3DS Emulator 2.9.4 BIOS
Hanne Rylaarsdam
Legally, BIOS must be obtained from your console. Various emulator websites have guides on how to dump BIOS. Other methods are piracy and cannot be discussed here or on the EmuDeck Discord.
For example, the photo below instructs you to place sega_101.bin (if you are playing JP games) or mpr-17933.bin (if you are playing US/EU games) directly into the Emulation/bios folder. Do not make a subfolder.
When "Optional" is written in the BIOS column, it means the emulator might have some extra functionality or will play the console's splash screen when you launch a game, but will run games without the BIOS.
When reading a Libretro wiki article, the System directory refers to Emulation/bios. Treat the Emulation/bios folder as the System directory and either place your files directly in Emulation/bios or create a folder according to the instructions on the various Libretro wiki pages.
RetroArch: RetroArch comes with a suite of shaders, bezels, cohesive hotkeys across the cores. A lot of small general emulator enhancements with an emphasis on a cohesive experience (for better or for worse).
Standalone emulators: Standalone emulators tend to be more up to date, more bleeding edge with the latest improvements to whatever that emulator emulates. Standalone emulators tend to come with a lot of additional features for the specific console it emulates. For example, melonDS features native microphone support. In the case of systems with both RetroArch cores and standalone emulators available, the standalone emulator usually also provides better overall performance than the RetroArch core.
Hello, in this post, i share with you, a 6.01 gb bios pack, i just, found some bios on the internet, and decide to spare people time to search for bios and download them, i got pretty much of all useful files to have, for the most known consoles, and some arcade files to use in emulators like MAME, or DEMUL, here is the file link (updated)
but, just a quick reminder, and its something that i can`t help, for people who want to emulate arcade games, there will be some problems, you will need a few more files, for this, you will need to search online, i dont play a lot of arcade games, but if you want just contact me to add some more files to the archive, and this counts for every emulator, just to help more people.
In order to emulate some home consoles (Playstation 1/2, Sega Saturn/CD/32x, etc.) a dump of the system's BIOS is required to emulate the console. Out of the Nintendo 64 emulators I have found online, none require the BIOS for ROM playback. How can N64 emulators work without the system BIOS? Is this because of the way the Nintendo 64 system was architected, or choices made by the author of the emulator?
RetroDeck is an all-in-one emulation solution that uses EmulationStation as its main interface. Because it is self-contained, it will behave as a single app with all of its emulators pre-installed and configured. This is a great solution if you just want a simple emulation experience that you can access directly from your SteamOS environment. Moreover, the app is available as a FlatPak directly in the Discover app via Desktop Mode on your Steam Deck, making the installation process super easy. RetroDeck is in active development and not yet in a final release state.
By default, EmulationStation will prefer specific emulators. To change them out, enter the Main Menu by pressing START > Other Settings > Alternative Emulators and change them as you see fit. These are the emulators I prefer to use with some of the major systems in ES-DE (those that are changed from default are in bold):
CryoUtilities is a tool that will allow for some under-the-hood performance tweaks that improve gameplay smoothness for high-end emulators like Yuzu (Nintendo Switch). When used in combination with the PowerTools plugin featured below, you can have improved gameplay with very minimal work. This tool was created by YouTuber CryoByte33, and you can find his in-depth explanation of the tool and its benefits in this video.
PowerTools: PowerTools is a plugin that will allow you to tweak specific emulators and games for the best performance. For example, it works really well with Dolphin by allowing you to reduce the number of CPU threads used by the app from 8 to 3 (be sure to also turn SMT OFF), which will make the 3 threads perform at a higher clock speed and provide smooth gameplay.
The PlayStation can play just fine on RetroArch with all the bells and whistles, but the standalone Duckstation emulator is excellent, too. It also has a sweet radial Quick Menu that can be activated by scrolling the left trackpad near the bottom-left which makes navigation super easy. You can see a demonstration image of a similar menu in the 3DS/Citra section above. Be sure to enable the PS1 controller profile to access the Quick Menu.
Performance and compatibility: Xbox emulation on the Steam Deck is unfortunately not perfect. To see whether a game will be compatible with the Xemu emulator, check out their compatibility list. If the game is compatible, is will likely play at an acceptable level when using an Internal Resolution Scale of 1x (the default set by EmuDeck). Some games may run at a 2x resolution; to set this, press SELECT + START to bring up the Quick Menu, then navigate to Settings > All Settings.

Unless I am missing something, EVERYTHING played through EmulationStation needs to be using the default Steam Deck profile, unless you want to keep swapping back and forth. The emulator-specific profiles only really work if you launch them separately through Steam.
Thanks a lot for this amazing guide! One questions: Is there an option to change the languages for the RetroArch Emulators? I was checking all options but for I have no options for the emulators directly, for example PPSPP. Thanks a lot!
Russ, coming back to this months later now that I have a Deck. I have everything set up, but my problem is that launching GC/Wii games from Emulation station prevents the deck from using the Per-Game profiles in performance settings and Power Tools. Is there any way to circumvent that, besides launching those from Steam library or through the emulator?
BIOS dumps contain intellectual property therefore it is illegal to distribute them without consent from the manufacturer. My guess is that most developers do not want to include any intellectual property in their emulators. It is the same reason why you won't find emulators being distributed with game ROMs.
Emulator: lr-mess
Rom Folder: advision
Extensions: .zip .ZIP
Bios: advision.zip, containing two files, b225__ins8048-11kdp_n.u5 (MD5: 5729638bd856c475678467a353bd921c) and b8223__cop411l-kcn_n.u8 (MD5: fc5e71445e4947a9d00eedbc66b13a8f). This must be in the roms/advision folder. NOT THE BIOS FOLDER!
Notes: Because this uses the mess emulator, there's a little more work involved in getting the games to run in which the rom must be named exactly as shown in the bios/mame/hash/advision.xml file. For example, Defender rom must be named defender.zip. You'll also need a copy of this advision.xml file in /roms2/bios/mame/hash/advision.xml (or /roms/bios... if using a single SD card).
Emulator: lr-mess
Rom Folder: astrocde
Extensions: .7z .7Z .bin .BIN .zip .ZIP
Bios: astrocde.zip (must be in the roms/astrocde folder. NOT THE BIOS FOLDER!)
Notes: Because this uses the mess emulator, there's a little more work involved in getting the games to run in which the rom must be named exactly as shown in the bios/mame/hash/astrocde.xml file. For example, The Incredible Wizard rom must be named wizard.bin. If it is zipped, it must be named wizard.zip.
Emulator: (lr-flycast) lr-flycast_xtreme lr-reicast_xtreme retrorun retrorun32
Rom Folder: atomiswave
Extensions: .7z .7Z .ist .IST .zip .ZIP .bin .BIN
Bios: awbios.zip (need to be placed in a folder named dc within the bios folder)
Note: Thanks to bignella for testing and compiling a list of the performance of various Atomiswave games using the retrorun32/flycast32 rumble emulator/core combination. See here.

Notes: The blueMSX core requires the 'Databases' and 'Machines' folders from a full installation of blueMSX.
You can download the 'Databases' and 'Machines' folders from an official full standalone blueMSX emulator installation.

Emulator: (lr-sameduck) lr-mess
Rom Folder: megaduck
Extensions: .bin .BIN .zip .ZIP .7z .7Z
Bios: None
Notes: If you want to use the mess core, there's a little more work involved in getting the games to run in which the rom must be named exactly as shown as the software name in the bios/mame/hash/megaduck.xml file. For example, Arctic Zone rom must be named arczone.bin. If it is zipped, it must be named arczone.zip.
