  • With some epic 8-bit styled artwork Cyber Shadow is out now | GamingOnLinux

    Cyber Shadow from Aarne "MekaSkull" Hunziker and Yacht Club Games is an epic throwback to the likes of Ninja Gaiden and Shadow Of The Ninja and it's out now with Linux support. Nice the see Yacht Club give a hand to another developer, after their success with the Shovel Knight series.

  • Monster taming and farming mix in Ova Magica is up on Kickstarter and already funded

    Ova Magica, a blending of casual farming in the spirit of Stardew Valley and Harvest Moon blended with monster taming and battling like something out of Pokemon is now live on Kickstarter. It managed to get fully funded within the first 2-3 hours, which I'm really not surprised about. The early tech demo was promising and it has such a great idea.

    Thankfully it's another that will support Linux too and the developer has been very clear about this. The Kickstarter campaign also lists it nice and clear as "The game will be released on PC DRM-Free, on Steam (Windows, Mac OS and Linux), Nintendo Switch, Playstation 4, Playstation 5, Xbox One, Xbox Series X/S.".

  • Plex Arcade is a retro video game streaming service that excludes Linux users

    Unfortunately, there is one big catch -- Linux users are being left out.

  • Seriously deep monster-catching dungeon-crawler Siralim Ultimate releases in March | GamingOnLinux

    Ready for a run through the dungeons? How about to catch 1000s of monsters? Siralim Ultimate will see return of the deep RPG when it enters Early Access on March 12. As confirmed in a Kickstarter update, the Linux port is also now available and ready for the release with Beta backers already having access.

  • Colony building sim Maia surprises with a big feature release, gets ray-marched shadows

    I always have a soft spot for Maia, a colony building sim from Simon Roth of Machine Studios with its very different take on building up a space colony on a distant world.

    Unlike RimWorld and other colony building games, Maia is more about looking pretty and providing some hard-science. It's a little difficult, in some ways a bit buggy but it always has such huge potential to be awesome. After a break, Roth is back to updating the game and this latest release is huge. One of the big additions is a new "ray-marched voxelised shadow system" which is pretty fancy and allows "every light in your base to cast accurate dynamic shadows into the world".

  • Try out Luxtorpeda, a Steam Play tool to run games in native game engines | GamingOnLinux

    There's quite a few games available on Steam that either don't support Linux, or do support Linux but like the Windows release there's a better way to run it perhaps with an open source game engine. Luxtorpeda will help with that.

    It's a project we briefly mentioned in a previous article talking about Boxtron, another Steam Play compatibility layer to run games on Steam that use DOSBox in your native install of DOSBox. Remember - Steam Play is just a feature, that runs different compatibility layers on Linux so anyone can make one. What Luxtorpeda does, is allow you to run various games (an expanding list) on Steam inside a native Linux game engine be it open source or otherwise.

    The original Luxtorpeda project only supports a few titles, but there's also the much newer Luxtorpeda-dev that is continuing the development which will hopefully merge together one day. Luxtorpeda-dev works with games like Cortex Command, Caesar 3, DOOM 3, Doki Doki Literature Club!, Freespace 2, Good Robot, Gothic 2: Gold Edition, RealRTCW, Return to Castle Wolfenstein, RollerCoaster Tycoon 2: Triple Thrill Pack, WRATH: Aeon of Ruin, Warzone 2100 and plenty more.

  • Super sweet chilled-out game Kind Words has a nice free content update | GamingOnLinux

    Kind Words is one of the most chilled-out games around, although calling it a game feels a little weird. You write anonymous caring letters to real people around the world and it really is sweet. The developer mentioned how over 3 million messages have now been exchanged in game and thousands go through it each day.

    Writing about the update, the developer said "We are humbled to have Kind Words become a regular part of so many people's lives and, in keeping with long-standing international custom for developer-player relations, we offer you this traditional gift: a giant, looming beast and some mittens."

  • GraviFire is a block-pushing puzzler with a gravity twist now on Linux | GamingOnLinux

    Love your block-pushing puzzle games? GraviFire released back in November 2020, and it recently gained Linux support.

    Taking the basic idea and pushing around blocks, it mixes things up with a few nice twists. The biggest one being that you're also dealing with gravity, so all blocks will be sliding around towards the same direction at the same time. It looks like it adds a nice bit of complication to the genre.

    "The green fire has been abducted by evil aliens, who force him to solve puzzles for tests. Need to pass all the tests to be able to return the green fire back to his home. You have to brainstorm over 50 levels. Gravity, movement, killing lasers... What else the aliens have prepared?"

Want to play Nintendo DS games on your Linux system but can't figure out how? Back in the day, Nintendo DS was a very popular handheld console with a huge collection of games. But over time, advanced consoles were launched in the market that rendered DS obsolete.

Luckily, several emulators are available that allow you to play classic Nintendo DS games on your system. DeSmuMe is a great example of a stable Nintendo DS emulator for a Linux machine.

Best Game Console Emulators for Linux

Filed under
Linux
Gaming

This article will list popular game console emulation software available for Linux. Emulation is a software compatibility layer that emulates hardware components of game consoles, instruction sets and related APIs. Emulation software can emulate CPUs, GPUs, audio hardware and many other such physical components available in real game consoles. Emulation allows you to play console exclusive games that are otherwise unplayable on PCs. Games running on these emulators see emulated components as if they were parts of a real game console and they cannot see the underlying platform (PC) on which the game is running on.
Developing an accurate game emulator for PC is an extremely difficult task, involves reverse engineering and many times developers have to sacrifice accuracy to improve compatibility. Emulators require original file system dump from game consoles. Some emulators emulate these components as well making it easier to play games. To play games on emulators, you must have game files, typically called ROMs.

VICE v3.5 | Versatile Commodore Emulator on openSUSE

Filed under
SUSE
Gaming

I recently received a little bit of a ribbing, I suppose, via email about not writing about emulators that were not of the Nintendo vintage. This is a fair criticism, I probably spend more time messing with Commodore 64 things such as chatting on IRC with a Commodore 64 or playing with my new THEC64 Maxi (more on that at a later date).

I have been doing some dabbling with the Commodore 64 again, but instead of just running or configuring things, I am interested in doing some application development. Instead of playing, doing something useful and practical. For real. That said, on a fresh clean installation of openSUSE Tumbleweed on my HP EliteBook I decided to install the latest VICE Emulator using the Open Build Service and do a little poking and playing around. It had been a while since I used the emulator.

[...]

Generally, it is more common to see some sort of Raspberry Pi OS or Debian based system as a retro gaming machine but the fine folks of the openSUSE community keep the repos up to date to have the latest in retro Commodore experiences. I love seeing the work being done to keep the Commodore experience alive. I know that much of this work has trickled into other projects which is what make the community based open source projects so wonderful.

I do want to highlight two individuals that are directly responsible for my excellent experience on openSUSE: Wolfgang Bauer and Karol Sławiński. You see these two names on the package change log for the last year. My sincere thank you goes to them.

If you haven’t kicked the tires of VICE recently, I highly recommend downloading version 3.5 and giving it another try. The GUI is better, the sound and video is better, the system controls are better based on the change log, the underpinnings are better. I think you will be pleasantly surprised on this refreshed experience.

    Speaking in a forum post, studio head Jamie Cheng mentioned they've "agreed to deal for Tencent to purchase a majority stake in Klei Entertainment" and that "Klei retains full autonomy of creative and operations across all aspects of the studio, including projects, talent, and more".

    Klei have actually been working with Tencent since 2016, as Tencent helped Klei distribute games through China on the WeGame platform and more recently a mobile Don't Starve game. Cheng also mentioned how a "large proportion" of their players are actually from China.

  • Return to Castle Monkey Ball might be the weirdest mashup ever | GamingOnLinux

    Combining elements of the Wolfenstein 3D classic first-person shooter with the rolling gameplay of Super Monkey Ball, what could go wrong? Return to Castle Monkey Ball is quite hilarious. Pointed out by a reader earlier this week, it's a web game you can play on itch.io right in your browser so there's no downloading and the idea actually works quite well. Amusingly so and it's pretty challenging too.

    The idea here is that you're rolling your way through some cramped hallways, while soldiers are trying their best to shoot you. Smash into them to hurt them, keep rolling and collect bananas to boost your score and hopefully make it out alive. Probably one of the most unique mashups I've seen lately.

  • Ballsy! World Cup 2020 is a wonderful throwback to Sensible Soccer | GamingOnLinux

    Remember the classic Sensible World of Soccer or the original Sensible Soccer? Classics from the 90s and Ballsy! World Cup 2020 is a wonderful take on it. Note: key provided by the developer.

    I have seriously fond memories of SWOS, playing endless hours on the Amiga a long time ago. Ballsy really does feel like it both mechanically and visually although naturally it's more modern and looks a lot cleaner. After originally releasing in October 2020, the developer decided to port it in December 2020 to Linux.

    "Tired of these sluggish, scripted modern football games? Still like some physics momentum in your retro footy game? Search no longer! Ballsy! offers that fluent feel for flowing football fans. The European football, that is, so, not handegg. Though truth be told, the term 'soccer' was actually invented by the English, so it doesn't deserve all the hate it gets."

    We have received many talk submissions from people from all over the world and while it was a heartbreaker, we had to make some selections to fit in the schedule. We want to thank warmly all the people who proposed a talk.

    Because of the incredible quantity of interesting proposals, we will try to host another conference soon, so if your talk didn't make it this time, please consider submitting it for the next event! Thank you all for your patience with us, we already learned a lot from this experience and we can't wait to work with you again!

    [...]

    Watching the conferences is great, but many of you may also want to discuss the contents together and perhaps ask questions to the speakers. As the talks are pre-recorded, you will not be able to ask your questions live after the talks, especially since some speakers may be out of the timezone at the time of their talk.

    This is why, in addition to the live streaming we have set up a Rocket.chat platform that you can join freely. There, you'll find one room for each talk. You can join each room to discuss and eventually ask your questions. In some cases, the speaker can be online too and will answer your questions directly!

  • Shots fired in disputes over OSS-as-a-Service

    Cloud services are the great disruptor of both IT organizations and vendors, and wrapping open source software around a service is the latest flashpoint. The open source development model has proven to be an incredible incubator of innovative software by democratizing and distributing the conception, design, implementation and debugging of new titles, advantages that were thoroughly explored more than two decades ago in the book, The Cathedral and the Bazaar. Although open source has since been adopted, encouraged and sponsored by every major software company, its origins were decidedly non-commercial with utopian overtones of liberating code from the tyranny of proprietary shackles. The earliest open source projects, notably Gnu Emacs and other tools from the Gnu Project, embraced this idealistic ethos with a restrictive, comprehensive license, GPL, that applies to derivative work using the code.

  • ROC and Precision-Recall curves - How do they compare?

    Both curves offer two useful information: how to choose the positive class prediction threshold and what is the overall performance of the classification model. The former is determined by selecting the threshold which yield the best tradeoff, in adequation with the prediction task and operational needs. The latter is done by measuring the area under the curves which informs about how good the model is, because by measuring the area under the curves, one computes the overall probability that a sample from the negative class has a lower probability than a sample from the positive class. With scikit-learn, the values can be computed either by using the roc_auc attribute of the object returned by plot_roc_curve() or by calling roc_auc_score() directly for ROC curves and by using the average_precision attribute of the object returned by plot_precision_recall_curve() or by calling average_precision_score() directly for PR curves.

Open Hardware: Raspberry Pi, Arduino, Thomas Petazzoni (Bootlin) on Training

  • Qsync fixed on the Pi4 and FF compiled

    The Raspberry Pi4 does not have a hardware battery-backed clock, so relies on getting the date and time from an Internet time server. In EasyOS, Qsync is the utility that does that. At first bootup, QuickSetup has a checkbox to enable getting time from the Internet, which will launch Qsync. At first bootup on the Pi4, if you are going to connect to Internet via wifi, not ethernet, then there won't be an immediate Internet access. No problem, Qsync will run once the Internet connection is established. Qsync will run just once at bootup and after Internet connection. That's fine, but I couldn't understand why it would suddenly stop working. Then discovered that /etc/init.d/qsync was getting its executable-flag cleared.
