Rotating the displayed picture: possible?

[ZeroX4]

I have recently tried Atari Classics Evolved on the PC version of PPSSPP. This compilation includes games that, when played on a real PSP, require the player to physically rotate the PSP 90 degrees to the left.
Is it possible to simulate this in PPSSPP with a rotation of the picture, to play "portrait" games without physically rotating the monitor?

when i asked same question few months ago they said ppsspp actually have that option but only for mobile devices and i think not much in that case changed so far
