It'll probably be a few days to possibly a week before I have any mods worth noting. I'm not a coder in any respect, but like a lot of others I can interpret certain parts of simple game code and understand how the different pieces might work together. In a game like XSP it's easy to tinker around because of how quickly you can load the game up and see whether or not your changes were successful, and how the game engine responded to those changes.
The most coding experience I have is with TADS3, an old text adventure system, that I used to build simple AIF games (Adult Interactive Fiction). I never released anything since all the stuff I did was just for my own enjoyment and to attempt to learn a bit about coding and storytelling, and everything I built was extremely simple. But the benefit of playing with that old TADS3 coding was that it was a language based loosely on C++ and Javascript, so I can now somewhat understand what I'm looking at when I open up the stuff in XStoryPlayer. It seems to be also build on C++ but I'm not 100% certain of that--like I said, I am no coder. I'm more like a code thief or a copypaster.
If you want, I could get a few of the more substantial mods that others on the xmoon forums have created and reupload them to mega or something. Most of those mods have been around on the xmoon forums for years so I can't imagine they're going anywhere, but if the community here would appreciate I don't mind trying to put together a modpack or two. They're usually several gigs in size though, this game tends to be a bit bloated.
I know a lot of players really love the Fast Sex (aka Dungeon) stuff in XSP, and I do too, but I like a little context with my H-games, so I've been trying to add more fun stuff in the Tentacle Dreams story that comes with 3.5. Eskarn on the xmoon forums made a fully custom story for 3.5 (Eskarn's Night Out) but I have a lot of problems with it--saves don't work correctly so you have to start over every time, and it's pretty normal for it to bug out and have the characters stop interacting with you, meaning you have to start over once again. Because of that, I can't really recommend it--Not really good for a fap session imho, kills the mood. It's worth checking out if you're bored of the current offerings though.
I'm thinking of trying to dig into Eskarn's code to see how he did the story elements and custom rooms. The apartment he created in that mod is fantastic and would be a great setting for something similar to a House Party style story in the XSP 3.5 engine. Maybe we could incorporate the two cloned variant girls from Dungeon Ex into that, too...
That's probably beyond my means, but a man can dream. I'll post up anything solid I get working here, if and when that ever happens.
