Hi there, I am writing an homebrew which would hopefully allow to take screenshots at anytime while the Wii U executes. I already managed to get VPADRead hooked thanks to function patcher from loadiine's code and I am also able to hook such function whenever a title gets loaded.
The only thing I am missing is a way of accessing the raw video buffer of the DRC and/or TV in order to be saved to sd card after a specific button press (which wil be checked thanks to the VPADRead hook). Is accessing the video buffer something that can be done with kernel privileges or do I need IOSU access?
It seems the browser is able to access this data when sharing screens on miiverse, so there must be a way even without an exploit, but don't know how...
-EDIT- Maybe I found the right function, should be GX2SetTV/DRCBuffer.
