AlfredoDore: some games started working with the ddraw of Dino Crisis 1 and 2, in this case DX Ball, a game that my mother used to play when I was a teenager (I was 11 years old). These days I downloaded it to try to play and the game practically doesn't work, only ddraw compact, however with errors, but the one from Dino Crisis made it load correctly, you can even use shaders
