Solution for me
I write here what made me run the game (on Win 8.1 + GEForce GTX 960) after years of trying !!
First of all, the "DDERR_UNSUPPORTED" error was related to a missing resolution that the game was trying to use (320x240), and in fact I didn't have it in my list.
Using NVIDIA Control Panel I added 320x240 as a Custom resolution (you should disable Dynamic Super Resolution from the 3D options to make it work)
Then, because Windows don't like resolutions inferior to 1024x768, and doesn't show them, you should force at least once the change from the NVIDIA Control Panel, go to the Windows list of resolutions and you'll see now the newer one too. (Then you can put up again your normal res)
Then, just put the executable in compatibility mode "Win 95" or "Win 98/ME" to prevent a crash.
Now the game should work, with just an issue, the cinematic intro could be black... but it doesn't give errors and I don't know why it's like that... anyway the game works for me with this solution
