Good Evening All,

I think this might be my first time ever posting on here. I apologize ahead of time if this is the incorrect forum for this discussion. What I am looking to do, if it is even possible is I want to create a new modding program for The Sims 3. The issue is, I am using Linux (Ubuntu 24.04 to be exact), and many of the standard Sims 3 tools that people use simply don't work on Linux, at least not out of the box, without using WINE, Winetricks, Bottles, Protontricks, using a Virtual machine in Virtualbox (which comes with it's own issues). The other day, and I don't know if this was caused by a recent Ubuntu update, but I WAS able to TSRW to make mods for the Sims 3, however now its malfunctioning again, and quite frankly I'm kinda sick and tired of TSRW, and having to put up with all its nonsense. From poorly formed workflows, to being a giant pain and unwieldy to use, to annoying proprietary formats that data is saved in, I am kind of tired of dealing with TSRW, and I would really like to develop a cross-platform, non-proprietary, open source Sims editor that basically does it all, you can create GEOM models, edit them in realtime, check to see if textures will work in realtime, generate Sims3Packs OR if you prefer just RAW packages, an editor where you can make clothes/outfits, objects, textures etc. The thing is... now in 2026, I know the game is several years old, and I'm not sure what resources there are for knowing how the game's core systems work, but this is a project I would like to do, if there was anyone who could point me in the right direction where to even begin finding info for how stuff works. About me, I'm a 43 year old post veteran who works in the IT / Tech support sector. I studied computer science and programming in particular as my specialty, and its not a matter of needing the skills to do so, I have those. I am just not sure where the information would be for how things work. I am sure everyone would love a replacement for the buggy mess that is TSRW. Also this opens modding up to people on Linux and Apple if I can pull this off. I used to make some mods before using TSRW, but now since I'm not on Windows anymore it's being even more uncooperative.
