Can anyone give me an idea as to why Outrun 2 SPDX FFB is not working?
Did you put the files in the right place - most games you just dump the files into the same folder as the game's exe, but Lindbergh games like OR2 have the files split. Some go in the game's elf folder, some go into the TP/TP folder. If you open the FFB GUI, and click the setup instrucitons on the bottom tile, it's in the notes.
Boomslang, those instructions there don't mention the fact you need to have ALL the files in the game exe/elf directory first, or the GUI won't open, and then you need to move the SDL2.DLL and openGL.dll files into TP/TP... (the same ones? Or is it ok to copy them to both places up front and leave them there?)
GCS, if it's not that, have you got everything working
without using the logitech profiler? It might not know how to recognise the game, which is a linux-based elf executable running in some sort of wrapper or whatever. So maybe set the default profile to work for OR2 to test, or just don't use it at all. There's also the two version of the OR2 plugin, or real, one custom. And the feedback isn't huge - you have to go for a real excursion onto the shoulder to get much FFB, i find.
