You will notice "tags" in front of each title like [W] or [AL] or [ALW]. Those are the platforms the game is compatible with be it "official" or through wine/proton which are like this:
| Letter | Platform |
|---|---|
| A | Android |
| B | BSD |
| IRL | Real Life |
| H | Haiku |
| L | Linux |
| M | Mac |
| M | Online |
| P | Proton |
| S | PS |
| N | Nintendo |
| W | Windows |
| * | Has many other ports |
| X | Not fully open source |
- Tags Only represent platforms that the publisher publishes binaries to, If you don't find a tag you might still be able to (probably) build it yourself from source.
- Games that run natively on linux won't have the Proton tag. (Though all open source games I found so far run natively on linux)
- Games with Proton support will have a link to ProtonDB so you can check it's compatibility.
- Arcade is there for games i could't decide what genre to put them in.
