Hello there, just checking if someone ran either S3PE or the S3PI library itself on other means in an UNIX system without a VM or dual-booting. Specifically I'm using Ubuntu 25.10 but even advice from Mac players will be already very good to get!

Hi,

Sorry for not responding to this sooner.

You can run the latest versions of S3PE and S3OC via Wine. I do so with my global Wine prefix. You have to have .NET 4.0 as an installed dependency to get it working. You should be able to install that with the dotnet40 package via Winetricks (or Protontricks) on the prefix/bottle you want to install it on.

The S3PI library is also cross-platform with Mono. My CAS tool takes advantage of that with the Linux version (comes bundled with Mono and GTK# 2 for systems whose package repos don't supply those), so if you're a developer and thinking about making a tool with S3PI, you can make it cross-platform.

S3PE can also run with Mono, but the latest version of S3PE that works with Mono 6.12 (latest stable release of Mono at the time of writing) is 12-0317-0944. You can get it from their old releases folder on their SourceForge. I found that out by trying lots of versions and narrowing it down Older versions of Mono are worse still at running it.

I feel like I went that route after I had some issues with trying to run it in wine, but after seeing the reply above I may try it out again over here too.

It sometimes crashes when loading a LOT of keys at once (I was trying to edit basegame's text strings) but it works very well on Wine with winetricks for dotnet.
