I compiled this SDL2 project on AmigaOS4 which I will upload to OS4Depot soon.
https://github.com/AlynxZhou/flipclock (A flip clock supported by SDL2.)
Now I am trying to create a AmigaOS4 screenblanker based on this.
I found some screen blanker examples OS4Depot.net.
Is there a tutorial about writing a screen blanker based on SDL ?
How to combine OS4 blanker source code with a SDL project ?
