any game goes black screen

I have a feeling your videocard is an Intel IGP that's older than the HD series (most likely an x3100 since it supports dx10). Turn off buffered rendering and you'll start seeing graphics (although it will still be buggy as hell, and slow depending on the game.)

You should read this thread for more info on your video chip's status within PPSSPP: Attention: Intel Integrated Graphics Owners on Windows. Read This.
