Hi, little post to say that i ported Spout for Dingoo. You don't need Linux to use it, it's a native port.
Put the APP file in your GAME directory and choose 3D Game to see spoout.app and to run it.
That was only a test to understand how s2d sdk works.
You can see my webpage about it here : Spoout For Dingoo. Also, the website is in French
