Please remove dark layer on top of everythin in non buffered rendering

Yeah i get it would had to be done on particular games only but it would help and bring back original brightness, because of this dark layer on top of everything some games are dark in non buffered mode.
Actually many games look better with non buffered rendering, you have to upscale psp res at least 3 times in buffered to get as nice graphics but it also slows emu down.
