Celeste for Google Stadia

Celeste is now available for Google Stadia! If you have a Stadia account you should now be able to purchase the game on their storefront.

This is the debut title for FNA Stadia, FNA3D (unless you count the Solaroids Xbox demo!), and ANGLE for Stadia, a project I've been quietly hacking on for quite some time. It is not, however, the debut for SDL! Ryan managed to beat me to my own port by releasing DOOM 64 for Stadia a few months ago. Fitting, considering I managed to release a Switch game using his SDL-switch project before he could release his own game... we joke about PS4/PS5 support, but unlike Switch/Stadia that's actually, definitely a joke this time, because... well, that's just how it is for FOSS development on consoles.

Much like Switch, Stadia is really nice in that pretty much all the juicy stuff uses a standard like OpenGL/Vulkan (I did sorta have to bring my own OpenGL, but you get the idea), however Stadia is truly remarkable in that it is literally just a Linux system without a desktop or display server; if you have Linux binaries that don't link to libstdc++ (i.e. use Clang and libc++ instead) and don't use X11/Wayland there is a 99.99% chance that your existing binaries (yes, not just the code, the binaries) will work just fine on Stadia. For Celeste I swapped out the SDL and FMOD binaries, and that was the system port done. Seriously. Celeste.exe got some add-ons for networking features and a couple menu options def'd out, but the port really was centered around SDL and ANGLE, for the most part.

ANGLE was mostly covered by the existing Vulkan work, with the remaining work being support for the GGP extensions (including creating two new EGL extensions) and compliance with AMDVLK, which turns out to be a really good driver to target when you want an added layer of correctness testing on top of the Vulkan validation layers. That was largely done by Jamie Madill and Shahbaz Youssefi, who were extremely helpful in getting ANGLE Vulkan and ANGLE Stadia working. They played a significant role in the port's development, so shoutout to them for all the hard work!

SDL-stadia was where most of my time was spent. Because there's a whole new video and event system (remember, no X11 or Wayland), I had to write new implementations in... and, uh, can all console APIs be like Stadia's? Obviously I can't share any of its contents, but between the API itself and the dev environment it actually makes me really sad that Stadia is a streaming platform and not a local hardware platform, as I would much rather develop for Stadia than any console... it's a real shame that it's cloud-based, because it really is a technological feat in pretty much every other regard. I just really like having my hardware and software run locally a wee bit too much compared to the average person.

In addition to being really good on its own merits, it also shines a very bright light on how close Stadia is to desktop Linux, and how disappointing it will be to see all that good work on AAA games get vaporized and never see the light of day in a desktop Linux release (or even a Windows release, for that matter). I'll put it plainly: There is no technological reason that a Stadia game could not also be on Linux PCs, even factoring in the work to port direct Stadia video/event code to SDL (which is a tiny amount of work, by the way). Virtually every other aspect of developing a Stadia game translates directly to Linux PC game development. Seeing all that reusable work get torched is going to suck really hard.

On the bright side, those of us who do care can happily treat Stadia as a Linux system with the SDL lib swapped. It was pretty refreshing to have the majority of a console port's development be almost 100% in plain sight, and not have a bunch of internal code that will vanish when the generation is over. I'll probably look back at Stadia development fondly whenever I work on the next new proprietary console.

Announcing FNA3D

GitHub Sponsors!

I'm happy to announce that I am now in the GitHub Sponsors program! This means that anyone with a GitHub account can now subscribe to a monthly payment system that will allow me to continue my work maintaining the numerous FOSS game development projects that I maintain, including FNA and FAudio.

You can find my sponsorship profile here.

If you're on the fence about this, I'll give you quite the incentive: Microsoft is skipping all payment processing fees, so in addition to taking extra money out of Microsoft's pocket (which I think my audience will take some joy in...), everything you pledge will go directly to me. A slight change of pace from Patreon's usual scams, hm?

I've been very vocal about the poor state of the crowdfunding ecosystem, and I think the GitHub Sponsors program is very much what we've all been looking for. I think you'll agree, and I hope you'll pledge what you can!

Want a Linux game?

I'm now officially back to working on Linux games full-time! I have my own hit list as always, but I'm always looking for more projects! Now's a really good time to hit me up while it's on my mind. Don't forget, whether you're an indie developer or an independent developer, there's a good chance I can accommodate your needs!

Turn a minimal Fedora installation into a SteamOS box!

1. Write Fedora Workstation NetInstall ISO to a USB drive
2. Boot USB image, install Minimal configuration with standard partition layout matching SteamOS'
3. Set root password, create a user called 'steam', set a password for it
4. Reboot, log in as root
5. A whole bunch of commands:

dnf group install hardware-support
dnf install Xorg xorg-x11-drv-evdev libglvnd-egl vulkan-loader.x86_64 vulkan-loader.i686 lightdm flatpak NetworkManager-wifi kernel-modules-extra bluez
dnf config-manager --add-repo=https://negativo17.org/repos/fedora-steam.repo
dnf install steam steamos-compositor steamos-modeswitch-inhibitor.x86_64 steamos-modeswitch-inhibitor.i686
setsebool -P allow_execheap 1
systemctl enable sshd.service
systemctl enable lightdm.service
systemctl set-default graphical.target

6. Edit /etc/lightdm/lightdm.conf:

pam-service=lightdm-autologin
pam-autologin-service=lightdm-autologin
user-session=steamos
autologin-user=steam
autologin-session=steamos

7. Create /var/lib/AccountsService/users/steam:

[User]
Session=steamos
XSession=steamos
Icon=/home/steam/.face
SystemAccount=false

8. Reboot, should work now!

9. Additional steps for NVIDIA users:

dnf config-manager --add-repo=https://negativo17.org/repos/fedora-nvidia.repo
dnf install kernel-devel dkms-nvidia nvidia-driver-libs.x86_64 nvidia-driver-libs.i686
reboot # Should be using the NVIDIA driver now!
