RetroArch with Flatpak – Distro-independent Linux version!

RobLoach

Flatpak LogoInstalling RetroArch on Linux has just become a whole lot easier with the use of Flatpak. Flatpak provides a common standard in which to install sandboxed applications across many different Linux operating systems and desktop environments. Along with the Flathub repository, installing RetroArch with Flatpak becomes a breeze.

Install Flatpak

The first thing to do when getting up and running with Flatpak is to install it. There are many different ways to install Flatpak, so I’ll let you decide the best for your distribution. Once installed, you should be able to run the following command to see how to use it:

flatpak --help

Welcome to Flathub

Add Flathub

Much like your favourite package manager, Flatpak uses repositories to manage available applications. Flathub is a quickly-growing Flatpak repository, which is where RetroArch is available from. To let Flatpak know about Flathub, you’ll have to add the repository to your remotes:

flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Install RetroArch

Now that the flathub remote is available, you can now install RetroArch on Flathub:

flatpak install --user flathub org.libretro.RetroArch

Run RetroArch with Flatpak

When RetroArch is installed through Flatpak, it will automatically become available through the system menu and you can run it as normal. Alternatively, you can also run it through the terminal:

flatpak run org.libretro.RetroArch

With Flatpak, you can install applications on Linux very easily, no matter what distribution or desktop environment you use. Flatpak repositories like Flathub provide a central hub in which to keep applications up to date. This revolutionises the way applications can be installed on Linux, and provides just one more easy way to install RetroArch.

More new cores: MelonDS, SameBoy, ARM Linux cores!

Libretro Team

This week will be all about a dripfeed of new cores along with a version bump of RetroArch, which will be needed for some of the new cores that will be arriving this week.

MelonDS

This is an up-and-coming Nintendo DS emulator by StapleButter, and it now has a libretro port. Some of the things that are still not properly implemented is touchscreen/mouse support and multithreading for the software 3D rasterizer, but we will take care of that soon. This emulator might not yet be a replacement for DesMuMe, but it’s quickly progressing so definitely keep your eyes on it, as DesMuMe certainly needs some competition.

You can get this new core on our buildbot. Start up RetroArch, go to ‘Online Updater’, and check for ‘MelonDS’.

For more information on MelonDS, check out its official homepage here.

Available for

The MelonDS core is currently available for:

  • Windows (64bit/32bit)
  • Linux (32bit/64bit)
  • macOS
  • iOS
  • Android

BIOS instructions, etc. (required)

MelonDS requires a real BIOS file in order to work. These need to be placed inside your System directory. If you don’t know where your System directory is, inside RetroArch, go to Settings -> Directories and read where your System Directory is located.

The following three files are all required:

  • bios7.bin
  • bios9.bin
  • firmware.bin

 

SameBoy

SameBoy is an accuracy-focused Game Boy/Game Boy Color emulator in the vein of Gambatte. We now have a libretro core of it and its author has also helped us earlier with some implementation details, so that is very much appreciated!

Some features that are still missing is savestate support, but we intend to get that done soon.

For more information on SameBoy, check out its official homepage here.

Available for

The SameBoy core is currently available for:

  • Windows (64bit/32bit)
  • Linux (32bit/64bit)
  • macOS
  • iOS
  • Android

BIOS instructions, etc. (optional)

Here is a tiny convenience feature you added – normally SameBoy relies on reverse engineered Game Boy/Game Boy Color boot ROMs in order to load. You can load these instead of the real BIOS file. For this libretro core, instead of requiring you to put these homebrew boot roms somewhere so that the emulator can read them, we have baked these into the core itself. So you don’t even need to put them somewhere in your system directory.

However, if you’d like to override these, you can do that too. Go to your system directory (if you don’t know what this is, inside RetroArch, go to Settings -> Directories and read where your System Directory is located) and put these files there:

Game Boy boot ROM – ‘dmg_boot.bin’

Game Boy Color boot ROM – ‘cgb_boot.bin’

ARM Linux cores!

Our buildbot is now providing fresh new ARM Linux cores for hardfloat configurations! These cores could be used for instance on Lakka-based devices as well as the NES Mini!

You can grab them here:

Miscellaneous updates

  • Mednafen/Beetle Saturn has been updated to the latest version.
  • Updates to ParaLLEl N64 core.

What’s still coming up this week?

In no particular order:

  • Redream (new Sega Dreamcast emulator made by inolen)
  • OpenLara (Tomb Raider 1 game engine, in early alpha development stages but already promising)
  • Dolphin (will have Gamecube controls only at first, will work for both GL and Vulkan)
  • Citra
