The official site has v1.2.15 for download and a lot of other libraries, but nothing about v1.3.
As I said above, there's no newer libraries to download (or at least I didn't found them), neither pascal headers other than jedi-sdl 1.0 (again I didn't found them, even freepascal points to jedi).
If any of you know about other headers, please share them. For now the force feedback feature will stay out of the project.
