my ppsspp is showing black screen...Pls how can i fix this

[retro]

716 is the last build without tne black screen, build 727 is with a black screen,
BUT 716 has another problem, the picture is some kind of mirror flipped and this problem goes all the way until build 19 (which is OK)
build 136 has the mirror rendering problem,

So for me the last good build I can use is 19

I hope this will help you, please contact me if you need more help...
