Glad to see that I'm not the only one excited about this project!
Are you kidding me. Do you know how long we've been waiting for something like this. I've been around sine when Konashion was alive, a project with these capabilities has only been attempted twice.
The first was someone named DoomKnight or something similar. He was going to remake the game from scratch in Unity. The problem was he was starting from the point of first leaning programming, so he didn't get a lot of attention. He disappeared about six months after announcing the project. He kept a dev blog though; wish I could find it if its still up.
If forget their name but someone else tried to make a fully web-based HTML5 version. He focused on building the Mods database and other superfluous things and his prototype sucked and didn't have the haptic feel SDT's animations do so no one payed attention and he disappeared after two months.
If you follow-through, this will be huge. I want to help you in anyway I can and encourage you early on because we all saw what happen to the past two examples.
I really don't want to break compatibility with the Loader mods. Luckily though it seems like it's possible to write a mod that edits the loader when loaded (partially what SDTL.swf is for). I don't know the limitations it will bring though. But it seems like a feasible solution for the time being.
I wasn't suggesting abandoning or not using the Loader. Branching the project would have been a better phrase to use. However I realize now I misunderstood how the Loader and SDTL work in conjunction. If SDTL.swf can edit and add to the Loader branching or merging the project isn't necessary and works out perfect.
I'm planning on adding a menu (similar to the one in-game) in the same window as the game but not inside the "flash player" .
That's exactly what I was thing, widen to window and add a new UI kinda like a split screen.
Ultimate Deepthroat is not a bad candidate
Ultimate Deepthroat is what DoomKnight called his project and I really liked it.
I'm thinking that it could be something like a popup that is opened either from the menu or a keyboard shortcut that shows the currently loaded mods and the current charcode.
If you're redoing the whole menu UI you could just show the name of the mod/file in the appropriate clothing slot also add slots for other types of mods.
