Gog officially support multiple versions of windows and Linux and Mac. Extending that, and asking devs to check for other operating systems which have very low user base is net odd beneficial to gog, the devs, or the users. Nothing stopping you from trying it, writing guides, providing patches etc. as other users have done with, say the Linux guy’s help.

Linux versions of games exist for x86 and x86-64. Raspberry Pis have ARM processors in them (armv7 or armv8/arm64), meaning the game devs would have to explicitly compile binaries for those architectures.

Games that already pack Android versions would most likely be easy to emulate, but I wouldn't have much hope for anything else to be honest.

Supposedly the reason unity3d uses Mono/.Net is for portability. I doubt they would provide binaries for ARM/Linux, though; probably just ARM running some mobile OS. While it's rare that using the Linux/x86(-64) driver will make Windows games run, I imagine having an ARM/Linux driver would work fine for most Linux-enabled games. Of the games I own, that would enable 72 games to work on ARM (well, 5-10 fewer due to closed-source native binary plugins). Still, no money in it, so it's not gonna happen in a closed-source project. The best you can hope for is working ports for open-sourced and/or reverse-engineered games such as Jagged Alliance 2, Star Ruler 2, Diablo, Morrowind, etc. In any case, not worth it to support directly on gog.

raspberry piiiiiiiiiiiiiiiiiiiiii

i mean id rather blueberry, but gimme

One of these days I'm going to attempt to get Avernum 1 working on a Raspberry Pi with the help of QEMU user mode emulation and WINE.

(I choose this particular game because it's old (so the CPU requirement can't be that high, particularly since emulation has a huge performance penalty), it's turn based (which means that the game running a little slow isn't a dealbreaker), and I've been able to get it to run under WINE (on an x876 CPU, of course) before.)

From what I loosely understand, most Raspi distros are Debian based to start with, and all Ubuntu happens to be is the table scraps of their LTS release.

With raspberry, problem is not OS as raspbian is a linux OS based on debian, but processor ARM familly is not X86 familly. And for this reason, if you want run linux programs compiled for X86 processors, you can't.

After, raspberry pi don't represent only one or two computers like mac computers. So making an effort to adapt games to raspberry pi will not be a loss of money. And I am sure that GOG can find a lot of programers ready to help in adaptation of games for raspberry pi.

Rather than trying to get x86 games to run on Raspberry Pi, the "focus" should be native RPi ports of games, for those who intend to play on it.

I love my RPi4 (4GB RAM) but I use it mainly as an internal file server at my home network, doing some mundane tasks that may take a long time to perform (downloading some rare movies or games from p2p networks with Amule trickling in at 5-15 kB/s, running gogrepoc.py on it, using it as my main media player (connected to my TV))... but I am not really that interested in playing games on it.

I did install some RPi games (ports) on it like A7Xp, Abe's Amazing Adventure, Abuse, ACM, Minecraft Pi, Seven Kingdoms and Adonthell - Waste's Edge... but meh. I played Adonthell a bit, some kind of hobbyist quasi-JRPG with very pixellated graphics. I got bored in the starting town already.

I guess gaming can be done on RPi too, but at this point I consider it a hindrance that apparently the RPi games are targeted to the lower-end RPi models with only 1GB RAM or so. I kinda wish they would have released RPi4 only as a 4GB RAM model.

I have 4 RPi 4s with 4GB of RAM. I use them 4 a lot of things (such as controlling LED arrays, running various python scripts), but mainly to look 4 binary pulsars (using docker, of all things). 4 all these tasks they per4m quite well, bang 4 buck wise. This message was brought to you by 0100. Rumor is there is/was an 8GB version as well that got postponed until they release an arm64 variant of Raspbian.

I can report Diablo via devilutionX works pretty decently on a RPi3. :)
Dosbox games have a good chance to be playable as well.
Given Unitys reputation for not being the most efficient and lightweight engine, I doubt you would find a lot of games that can run under the hardware constraints of the raspberry pie.
Games that are written in C# and use some lighter framework like FNA or monogame might actually be worthwhile to check out.(like Spacechem, Terraria or StardewValley(?)). Pretty sure mono is available raspbian.

Probably be on the Pi7 before it's even a realistic possibility, to be honest. Pi3 already has pretty good emulation of older systems thanks to Retropie and the like. So it's definitely something you're not alone in wanting.

Twister OS got box86 wine and dosbox already on it from new installation, it is recommended you use a raspberry pi 4, 4 - 8 gb, this might be the best OS to try something like this out on and it wont be long before we see all the GOOD OLD GAMES being played on raspberry builds of portable computers, (doom, monkey island 1, 2, full throttle, heroes of might and magic and all the good ones, ready to play on the go) ;)

I agree, emulating another system is going to be slower no matter what and the limited speed will get you. Games that have a ARM compiled binary would be best, or games that have a framework that already runs on the Pi and you just transfer the files from say the x86 to the new system.

Though other than say Unity, and a couple Visual Novel tools that support several platforms, i can't think of one that would be as easy to work with.

Hmmm with Amiga games being emulated on here, along with some games that are just roms with emulators and DOSBOX games, you'd think they'd have an easy way to extract the files to run on native emulators taking out most of the problems.

Almost makes me wish a number of devs were literally still making SNES/Genesis games and selling them as roms so you could keep easiest compatibility via emulators/Virtual Machines.
